Netheril

While the most known calendar of the realms is Dale Reckoning, there exists a far older measure of achievement, at least by humans: the Neth. A group of small farming villages that banded together for protection led to an empire of human wizards, cities that floated across the sky and a terrible, terrible arrogance that nearly stripped Toril of its magic forever.

The First Age
At the time, Netheril was a paradise of rivers, forests, lakes and plains. Netheril was unsuprisingly little more than a group of villages (Fenwick, Gers, Gilan, Gustaf, Moran, Nauseef and Janick) along one such lake. Soon after this alliance was named Netheril (after Nether the Elder who is assumed to be the leader) the nation proceeded to remove the threats close by. Seeking to widen its scope of both power and land it began expanding. This eventually lead the Eaerlanni elves to approach the humans. The elves taught the humans of this new alliance magic, and with talent unseen before (possibly because of the shorter human life span) the humans learned arcane spells with a fervor. Every denizen of Netheril was taught the very basic of spellcasting. Even average maids knew cantrips to make the broom sweep the floor. Those who excelled at the arts of magic became known as Arcanists, a rapidly rising political faction that was second only to the nobility of the nation.

History

 * Main article: History of Netheril

The history of Netheril is one of great advances in the arcane arts and great hubris on behalf of the civilizations greatest archmages. Thanks to excellently preserved Netherese records, written accounts from the 'Netherese Diaspora', and the fact that more than a few Netherese ciztizens live to this day (through undeath (eg. Ioulaum) or other means (eg. the inhabitants of Shade Enclave), historians have a comprehensive knowledge of Netheril's history.

The Fall
While Netheril's flying cities flourished in the sky, magical residue seeped into the earth below and became an affliction for a race of subterannean dwelling creatures called the Phaerimm. Eventually, the Phaerimm grew tired of their torment and began to retaliate. They cast spells which drained life and magic from the earth and the floating cities of Netheril, creating barren wastelands where there once were lush fields and areas of Wild Magic. As magic began to go uncontrollably awry, many of the Netherese arch-mages fled in search of lands where their magic would not go wrong, including Ioulaum, the wizard who first discovered the Mythallar and made the first floating city. The disappearance of the arch-mages caused panic, and people began to flee the land.

In an attempt to save his own floating city, or enclave, a young wizard prodigy named Karsus decided to cast a spell he had been researching for decades. In casting the spell, Karsus created a link between himself and the goddess of magic, Mystryl, and stole her divinity and power. At that very moment Karsus swelled with incredible knowledge of everything, including his mistake. The war between the Phaerimm and the Netherese was constantly damaging the Weave, which Mystryl was the only one capable of constantly repairing. To stop Karsus from completely destroying the Weave, Mystryl severed her connection with Karsus, and in the process destroyed herself. In the backlash from being disconnected from Mystryl, Karsus was permanently petrified and all magic around the world temperarily went null, causing the Netherese floating cities to plummet to the earth. The life draining magic of the Phaerim continued and the lands of the Empire eventually became the Anauroch Desert. Eventually all trace of the Netherese Empire was forgotten and buried under the sands.

Almost immediately after Mystryl died, she was reincarnated as Mystra, the goddess of magic who retained her position until the Time of Troubles. Fortunately, she was able to save three of the falling Netherese cities: Anauria, Asram, and Hlondath. Two other cities, the City of Shade (still in existence) and Opus (currently in the outer planes), were saved by Shar and Selûne respectively.

Almost all of the surviving Netherese forsook magic completely. The three cities saved by Mystra were later either destroyed or abandoned.

Survivor States

 * Anauria : The lands directly south of Netheril became the home of the Anaurians, who became renowned for creating fine swords and carrying on the magical legacy of Netheril. The lack of high-level magics and the mythallars severely hampered their efforts, however, and the kingdom was finally destroyed in a bloody and costly battle against an orc horde in 450 DR.


 * Asram : No sooner had Asram recovered from the Fall then it was suddenly struck by a horrendous plague that claimed all the Asramans in 306 DR. In the spring months that led up to what many call a repeat of the Dark Disaster, cattle were found dead in the fields and crops withered and died, sometimes overnight. During the first week of Eleasius, however, the plague struck the entire nation. Few survived.


 * Hlondath :The longest-lived of the survivor-states, Hlondathans immediately began blaming others for the fall of Netheril‚ discounting the news that Karsus himself had caused the destruction of Netheril. Their favorite target for such blame were the elves of Cormanthyr, whom they saw as “accomplices of the phaerimm.” They established good relations with the dwarves of Tethyamar, but otherwise concentrated on logging the nearby forest and herding cattle across the plains.
 * In 538 DR, the Hlondathans finally incited the Cormanthyr elves into a war. In what became known as the Crown Against Scepter Wars, the elves and Hlondath exchanged a series of blows back and forth. Time after time, Myth Drannor crushed Hlondathan forces, and the wars served only to weaken Hlondath.
 * The approach of the Anauroch slowly consumed fields and fertile plains, further scattering the survivors.

The Reemergence of the Shade Enclave
When the City of Shade, or the Shade Enclave, began to plummet as the world's magic was temporarily disrupted, it was saved by Shar and pulled into the Shadow Plane for a long time, but returned to the Prime Material Plane in the year 1372 DR. They now live on the north-western side of the Shadow Sea in the Anauroch Desert where they rule the Empire of Shadows. The inhabitants of the City of Shade often torture any Netherese that might be surviving in the area purely for the chance to glean information from them, but otherwise consider any Netherese weak.
