Earth

Earth was a largely non-fantastical world cut off from most of the multiverse. "Weary of the world around ye? Welcome to my world, where magic rules and dragons fly. Beauty meets the eye often here, and anyone can try to win a throne! Oh, aye, ye can do that in your world, too&mdash;but it's all more fun here."

- Elminster

Cosmography
Some sources claimed that this planet existed within an alternate Prime Material plane, but in actuality it existed within a crystal sphere on the same Prime Material plane as Toril,  though its inhabitants were unaware of the existence of crystal spheres. It was difficult to locate amidst the phlogiston and was potentially difficult to enter or traverse.

Gateways
The wizard Elminster Aumar claimed that there existed hidden portals not only between Earth and Toril, but to the planets of Krynn and Oerth. In this world's ancient past such portals were well-known and widely used, leading to legends on Earth of such fantastical creatures as dragons and griffons, but over time Earth's people collectively forgot about them and Toril in-turn was increasingly believed to not be real. But among those few who did know of the existence of these portals, they referred to Toril as the "Forgotten Realms."

Baba Yaga knew of Earth and had probably even visited in her dancing hut, which traveled all the worlds and planes. In its Hall of Gateways, a portal called the World Gate linked to every world Baba Yaga knew of, including Earth, as well as their respective Shadowfells and Feywilds.

Earth's part of the Prime Material plane was isolated and weakly connected to the other planes, with only some points having solid connections to the wider Prime Material, the Astral plane, and the Ethereal plane, while connections to the Inner planes were thin and weak and there were barely any connections to the Outer planes. Because of these limitations, magic-users from outside were unable to use some spells to get there, like gate, contact other plane, commune, summon shadow, while others were impeded to functioned differently. Similarly, extraplanar energies did not leak into Earth, so magical phenomena did not occur and magical creatures did not evolve, and Earth humans were not inspired to conduct serious research into magic. Hence, Earth was a magically null place and a forgotten backwater of the planes.

A spontaneous gate with a "vector imbalance" once spirited one Simon Weems of Earth to Havenmere in Cormyr, as well as a creature known only as the Demon from its own plane, circa Earth year 1988 CE. Adventurers needed to capture both of them in order to seen them home to their respective planes.

Geography
This planet was comparable in size to Toril,    with an equatorial circumference of about. The cloud cover of this planet resembled that over Radole. Their axial tilts and rotational periods were also comparable, though not identical. And much like Toril, it was orbited by a giant natural satellite, which made a full orbit every thirty days.

One of Earth's major landmasses was known as Eurasia, which separated into a geographic region known as Europe. One of the nations that could be found in Europe was known as Ireland. There was also a landmass known as Australia.

Calendar
Much like the Calendar of Harptos, the major calendar used by the people of this world marked its months based on the lunar cycle and a single year totaled 365 days.

Flora & Fauna
One source claimed that foxes were never native to Toril, and were actually brought from Earth, most likely France, by an adventurous halfling trader named Altho Minstrelwish around. He had plans to sell their fur (particularly their tails, termed "brushes") for fashionable attire, but found few halflings were interested because of their distinct smell. Fox meat, whether roasted or stewed, was even less popular. In the end, he let the foxes run wild, and in time they displaced the native Faerûnian lynx. The hin word for "fox" was rennard, after the French word for a fox, renard. However, it was known that foxes existed on Toril far before the 1 century DR, even in the times of ancient Netheril. Similarly, wombats were claimed to have been brought to Toril from Earth.

Much like on Toril, there were a variety of animals on this planet that people harvested ivory from. This included the tusks of boars, elephants, narwhals, walruses, as well as the teeth of hippopotami and cachalots.

Both worlds had the domestic animals known as cats and dogs. There were some breeds of dog unique to Earth, being difficult or impossible to find on others like Toril, such as Boston Terriers and Irish Setters. Likewise, many of the humanoids and monstrous beasts that could be found on Toril were absent from this planet. Some insects could be found on both worlds, including crickets, fireflies, and mosquitos.

Minerals
Both Earth and Toril exhibited the substance salt, though on Earth it was comparatively a far more major trade good. This was due to Toril having a greater abundance of the substance and because the people of that world had other means of preserving their food.

The refined alloys adamantine and mithril were not known to exist on Earth, but if brought to it they behaved the same as they did on Toril.

Much like the Realms, on this planet people cut gems found in massive form down into gemstones if they were of high value. These gems included agate, beryl, chalcedony, grossular, idocrase, jade, jasper, rhodonite, rock crystal, rose quartz, serpentine, tiger eye agate, and tourmaline. If not of high value, gems were typically weaker and they would be sold by weight for carving purposes. These gems included amber, jet, malachite, moonstone, obsidian, opal, and turquoise.

Other gemstones shared by Toril and Earth included bluestone, serpentine stone, flamedance, and Laeral's tears. These gemstones were usually known by the people of Earth as "ditroite", "verde antique", "rhodizite", and "beryllonite", respectively.

Besides using them for adornment or magical purposes, the people of this world had gemstones serve as representations of their deities or guardian spirits. Some of their legends spoke of gems forming from tears, growing on trees, being excreted by horses, or being spat out by a deity or hero.

Notable Locations

 * The forest Cottage of Ed of the Greenwood, where he was often visited by planar travelers. A large rock near this cottage, which Ed liked to relax upon and read books, resembled the battlements of Castle Grimstead.
 * Lake Geneva in the land of Wisconsin was home to Simon Weems, who dressed peculiarly in Earth attire and sold something called "insurance".
 * London, a major city.
 * The Pecos River was a river on Earth. St. Sollars the Twice-Martyred described the demon lord Orcus, Prince of the Undead, as "the meanest dude this side o' the Pecos", suggesting there was a dude who was meaner on the other side.
 * Elminster's favorite place to relax and find rest off Toril was found in Yellowstone National Park on Earth. He kept a magic portal there from his hideout within the planet Coliar, specifically to the Earth year 1894 AD. It was also here that he purchased German beer to sell to his friend Gamalon Idogyr.
 * There was apparently a place called "Downunda", possibly that world's Underdark.

Ancient History
In the most ancient times of this planet, its landmasses were all part of a singular body of land known as Pangea. Over the course of this world's ancient history, it would be visited by spelljammers on a few occasions.

On Toril, in the year, the mages of a nation on the continent of Faerûn known as the Imaskar Empire sought to replenish their population after a devastating plague. To this end they opened two great gates to another world, widely believed to have been Earth, and kidnapped numerous humans from different eras of that world's history to serve as their slaves. Those of Mulhorand hailed from a desert land given life by the seasonal flooding of a great river and those of Unther from another desert land. After transporting them back to Abeir-Toril, the Imaskari closed the gates forever. With them, these people brought their own societies, mature culture, and later, the gods of the Mulhorandi and Untheric pantheons. And over time, through Intermarriage between the desert people and the Imaskari, a new ethnic group would come to form known as the Mulan.

Later came a people from two lands: a collection of city-states known for their daring philosophies and a land of empire and glory; they had similar pantheons of gods. These were followed by folk from a rugged land with a culture tied to nature, the sea, and the warrior history of its dozen-king greater god. Each of these people brought their own societies and faiths, some settling around the time of Bakar in Medinat Muskawoon and others around the time of the rise of Netheril. Those that came from the rugged land had societies that were in some respects similar to the later silver elves' society on Evermeet.

Modern History
In the early stages of a time known as the Victorian era, a few spelljammers had visited this world.

Circa Earth year 1965 CE, Elminster first came to this world. He would go on to visit it many more times, seeking to learn about its ecology and societies. Around the same time as his first visit, a young boy who would come to be known as Ed of the Greenwood, began having vivid dreams of a temperate forest in the Realms during the winter season. Two of the Seven Sisters would appear in these dreams, alongside Mirt the Moneylender. It was circa 1975 CE when this boy would first become aware of Elminster.

In the, now a librarian, the man called Ed of the Greenwood assembled various journals, maps, and other works from Elminster Aumar into the first publication of the Forgotten Realms campaign setting. This included an introduction by Elminster's scribe Lhaeo, written on the last day of Nightal.

Around this decade a group of six young children stumbled through a portal that manifested at an amusement park, transporting them to a world known as the Realm. Years later the children found themselves on Toril and one of them, an aspiring wizard named Presto, became an apprentice to Elminster.

Later, Ed Greenwood and Steve Perrin "spent many long days" working with Elminster researching spells, spellbooks, and magic items. At Elminster's bidding, they compiled this lore into The Magister. In the (circa 1988 CE), Amelior Amanitas agreed to a request by Elminster, due to him generously sheltering Amelior after some incident in Volkumburgh, to provide author Jennell Jaquays the wealth of information he had regarding the North and its history. This culminated in the sourcebook The Savage Frontier. Around that time Ed of the Greenwood was exploring neglected corners of the Realms, sharing some of his lore with an elf from Poughkeepsie and a would-be conqueror from Portland. The former was particularly interested in the undergarments of King Azoun Obarskyr IV, much to his and Azoun's confusion.

When Ed of the Greenwood's team began working on a new boxset of the Forgotten Realms campaign setting he informed Elminster. Around the winter season the wizard stormed into the office of Ed's co-worker Jeff Grubb in a flash of lightning to inquire about this project and, having acquired by that time a taste for Earthly fashions, was dressed in a brown vest and faded blue jeans. Jeff Grub would oblige his request, going on to namedrop other projects they had in development &mdash; the H series, the Desert of Desolation, Beneath Illefarn, Waterdeep and the North, and the novel Darkwalker on Moonshae by Doug Niles.

Before abruptly leaving his office, Elminster informed Jeff Grubb that the continent of Kara-Tur was in fact part of the Realms. An exasperated Grubb quickly contacted Ed of the Greenwood to inform him of the wizard's visitation, only to be informed that Elminster was right next to him discussing the skyships of Halruaa. After ceasing communication with him, Grubb pondered how many other worlds had wizards that were involved in the campaign settings that their company published.

In, around the time of the Tuigan Horde's invasion of east Faerûn, Elminster came to Jeff Grubb to talk about their latest and upcoming writings on the Realms. These included the Avatar series, the The Empires trilogy, the Forgotten Realms Adventures, and The Horde. Grub would inform Elminster that, compared to their first publication of the Forgotten Realms, the Forgotten Realms Adventures would contain more info regarding Cormyr, the Dalelands, Sembia, and the Sword Coast in general.

During this exchange, Elminster admitted that in the few weeks prior he had been providing Greenwood information on cities in the Realms, such as Elturel, Marsember, Ordulin, and Westgate. He also admitted to having shown Alias the cover to the novel she was the protagonist of, Azure Bonds, and that she was greatly amused by it.

Though the boxed Campaign Set and Forgotten Realms Adventures would both be crammed full of information from Elminster, both were ultimately forced to excise numerous smaller factoids for space. Overtime these bits and pieces that were difficult to incorporate into books would pile up, as increased interest in the Realms left both Ed of the Greenwood and the wizard inundated with questions. Elminster became so further scatter-tongued as a result, Ed began to run several tape recorders throughout his visits. Seeking an outlet for all this gathered information, Ed would go on to write columns in magazines, such as The Everwinking Eye in the Polyhedron Newszine.

Circa Earth year 1985 CE, a major divine artifact of Oerth somehow wound up in the Victoria and Albert Museum in London.

Circa Earth year 1987 CE, at a convention known as GENCON 20, Ed of the Greenwood's company was presenting an adventure module called Waterdeep &mdash; set during the Time of Troubles, it loosely paralleled events they had described in the Avatar series. Elminster, who was featured in the module itself, would arrive to this convention and address the attendees with the following speech, "Ye'll hear tales tonight, aye, and other nights besides, until ye know them well. And all of them tell of folk getting hurt, and enduring hardship and suffering, and spilling blood, too much of it their own. And ye'll laugh and enjoy it and think it grand &mdash; as ye can be sure they did not, during its unfolding. High adventure, 'tis called; more's the joke."

Some Earth years after that, Elminster sent a large amount of reading material on Calimshan and the Land of the Lions to Dale Donovan and Steven E. Schend in preparation for a sourcebook they were working on, Empires of the Shining Sea. Bound in oilcloth, the packaged materials included sixteen massive tomes, over a dozen parchment and vellum scrolls, and many maps. And some of them were the works of King Haedrak and Count Gamalon. Much to the writers' frustration, at Ed of the Greenwood's suggestion Elminster had placed sticky notes on many of the documents in place of leaving notes with magic mouth.

Later, for a sourcebook about the Sea of Fallen Stars, Elminster provided Schend one of the four known copies of the Encyclopedia Serôsica with some personal notes. In one such note, he described the building style of merfolk in Serôs as being comparable to that collection of city-states, due to their emphasis on columns and carved works.

Around these decades Laeral Silverhand also regularly traveled to Earth to visit Steven E. Schend, whom she spoke to of Waterdeep, even if she did tend to interrupt his writing. He compiled this lore into articles for Dragon magazine.

At some point, Elminster went on to give game designer Chris Perkins a guided tour of the city of Waterdeep.

Religion
Ancient civilizations on this world worshiped a variety of different deities, much like people in the Realms did, though they often had pantheons that were more organized. In the 13 century of this world, faith in general was a dominant aspect of life for people of a region known as Europe.

Deities
A number of gods of the Egyptian pantheon, as well as the Babylonian and Sumerian pantheons, of Earth traveled to Toril and formed the Mulhorandi and Untheric pantheons, respectively.

The Greek pantheon was largely unknown in the Realms, with some exceptions. For instance, Poseidon had a small following on Toril, Prometheus and Tyche were once worshiped in the city of Medinat Muskawoon due to planar immigration, and Hephaestus had a book written about him, though he was considered an obscure deity. Tyche, a minor deity in her original pantheon, was also worshiped in Netheril until the Dawn Cataclysm. And Hermes would later romance the goddess Tymora in an effort to learn the fate of Tyche.

A number of deities within the Realms originated from the Celtic pantheon, Finnish pantheon and Norse pantheon. Many of the deities within the Lords of Creation, the major pantheon worshiped in the Kuong Kingdom, hailed from the Vedic pantheon, such as Garuda and Yama.

A number of animal spirits, foremost among them Eagle and Raven, were worshiped both by the green elves of Toril and the American Indian peoples of Earth. Some other spirits of the American Indian people, such as Shakak, were worshiped by the Azuposi of Maztica.

Magic
In an era on this world known as the "Dark Ages," the belief in the supernatural was at its peak. Some believed that, even during this era, the people of Earth were never as affected by arcane magic as the people of Toril.

Some believed that magic on this world was entirely absent, unlike the Realms, though Elminster was adamant that magic was at one point as dominant on Earth as it was in the Realms and that even in the planet's modern era it still existed. Thus that earlier period of the planet's history could be referred to as the "Age of Magic." In addition, people on this world were known to use gemstones for divination, as repositories of spells, or as protective charms against magic and evil creatures.

Magical potions generally worked the same on both Earth and Toril.

Art
Earth and Toril both had a rich and varied selection of music. They shared a number of musical instruments in common, though they were often known by different names. For example, pan flutes were known as birdpipes, recorders were known as songhorns, and tambourines were known as tantans. In addition, Dove Falconhand owned a magical harp that resembled a Celtic harp. Other instruments on Toril had no identical counterparts on Earth, like the tocken and zulkoon, though musicians would readily understand such instruments if introduced to them. Clarinets and saxophones were once unique to Earth, but at some point Elminster brought some of them to Toril.

Elminster once tried to steal the double-necked bass of a musician named Geddy Lee, but Ed of the Greenwood managed to dissuade him by pointing out all the electronic equipment he'd have to steal to make it function.

A traditional Celtic song was called "Dawn of the Day". It was similar in mood and tone, though not the actual tune, to "The Ballad of the Dream Weaver".

There was a nursery rhyme about a "Mother Hubbard" whose shelves were bare. And a novel by the name of 20,000 Leagues Under the Sea, copies of which somehow found their way on to the Nelanther Isles of Toril.

Both worlds had heraldry, though they operated on different sets of rules. The women of Earth often used a non-shield shape to display their coat of arms, such as a lozenge, while the women of Faerûn exclusively used shields.

Cuisine
There was a variety of unique and regional cuisine on this planet that Elminster adored. This included Australian beer, cocoa, Bailey's Irish Cream, mayonnaise, pina coladas, pizza, pumpernickel, a carbonated sugared drink known as cola, root beer, and many varieties of cheese, such as string cheese.

Elminster, a self-described gourmand, had a number of his own favorite Earth cuisines, including things known as Aero bars, ice cream, Mars bars, and Kit Kats. In terms of beverages, he was partial to cocktails, like pina coladas and tequila sunrises. He would often raid Ed of the Greenwood's wine cellar and larder, finding to his frustration one day a lack of ice cream due to Greenwood watching his diabetes. The wizard Khelben Arunsun was partial to liquorice. And nearly all wizards of the Realms that interacted with this planet were seen to delight in butter tarts.

Specialist bakeries here that sold breads, cakes, and pastries were known as "patisseries". A mage, likely Elminster, claiming to have visited "far places indeed", suggested such a name to Jemima Chisolm, owner of the Downunda Patisserie in Ravens Bluff.

Holidays
During this world's winter solstice, many of its inhabitants celebrated a holiday known as Yule, from which a more commercial gift-giving holiday would later be derived known as Christmas. This holiday had personifications in the form of mysterious figures known as Father Christmas and Santa Claus. Elminster was well familiar with this holiday due to his frequent visits to Earth, as were to a lesser extent Laeral, the Simbul, and Storm Silverhand of the Seven Sisters.

Whenever Elminster was on Earth during the Christmas season he would provide aid to people, gift food, as well as use his spells to provide shelter and warmth from the winter cold to those in need in. He also enjoyed masquerading as the mysterious "Father Christmas," performing small acts of magic observable to only one or two beings (particularly disillusioned adults and teens who have disavowed Father Christmas). He especially enjoyed showing up as such to Ed of the Greenwood's home on late Christmas Eve or early Christmas morn', taking the time to raid his wine cellar. These charitable acts, especially the masquerade, were done as part of his duty as a Chosen of Mystra to foster a belief of magic in others and strengthen their sense of wonder.

Martial Arts
Much like the Realms, this world had a number of unique fighting styles. Elminster once noted that one of these styles, aikido, bore similarities to a defensive fighting style practiced by the monks of St. Noradnar's Hermitage that revolved around disarming and disabling one's opponent.

Background
Throughout the years there has been a number of unique settings presented within D&D (and related systems by TSR, Inc. or Wizards of the Coast) that were alternate Earths, considered distinct from the Earth of this article.

Alternate Earths in the D&D system included the Victorian-style Gothic Earth from Ravenloft's Masque of the Red Death sub-setting, the "magic Earth" of the HR1-HR7 Historical Reference Series (which Chronomancer suggests may be the past of Gothic Earth), the world of Averoigne presented in Castle Amber, and the Crusades-set Earth presented in Dungeon #86's adventure "Mysterious Ways" and Dragon #284's prose "Pilgrim's Ties".

Alternate Earths from tangentially connected systems included the urban fantasy-style Earth of Urban Arcana, the Earth of Amazing Engine's "Magitech" setting, and the post-apocalyptic Gamma World of Gamma World.

Trivia

 * Alaska was used as a cheat code in the game Blood & Magic, which when entered would summon a gnome unit.
 * Dragon #209's article "Branching Out All Over" offered a wide variety of locations on both Earth and Faerûn where one could find the different branches of druids presented in The Complete Druid's Handbook.
