Sharn

The sharns were mysterious aberrations of transformed humanoids. They were best known as those responsible for imprisoning the malevolent phaerimm under the sands of the Anauroch desert. The sharns were also called by these lesser known names: shiftshades, blackclaws, shimmershadows, skulkingdeaths, and fhaorn’quessir, which was Elvish for “changed/altered/transformed people.”

The sharns were adept and monstrous sorcerers who served the alliance of deities known as the Pentad — the elven deities Corellon Larethian and Sehanine Moonbow, the dwarven god Dumathoin, and the human deities Mystra and Oghma. The sharn were composed of a variety of different races, including elves, dwarves, humans, and centaurs from fallen civilizations that willingly underwent magical transformations to turn themselves into sharn so that they could better preserve their civilizations’ lore. The sharn also prevented abuses of magic and fought against corruptions of the Weave.

All sharns shared a single group mind; they were one being with many souls and sensed what other sharns sensed and thought what other sharns thought. Rarely, the sharn mind did fragment back into the individual minds of its composite beings. Sharns could meld and flow together, forming black pools of liquid. There were black pools of sharnstuff in caverns in the upper reaches of the Underdark, particularly the Northdark, where the sharns made their homes. The sharns split off from these pools of themselves, and when they completed their missions, they melded back into them.

The sharns had the ability to create small portals through the ethereal and could broach nearly any protections or barriers with them. Each portal was a small translucent hexagonal window of purple light three feet in diameter that coalesced out of a swirl of purple motes, and each sharn could maintain up to three of them at once within about twenty feet (6.1 m) of their bodies. Although the sharns couldn't move completely through these portals, they could use them as windows into the areas they connected to and were able to cast spells through them as well as extend limbs through to claw or bite at their opponents. Sharns also frequently cast spells upon themselves which greatly increased their speed and agility. They didn't need material components or focuses for their spells, whether those spells were arcane or divine in nature.

The sharns weren't very numerous. According to one source, their society housed a lot of political argument and social intrigue, and their power struggles (which were typically based on ideological conflicts) were near-constant. The same source also stated that most of the elder sharns had phased out of existence, though this point seemed to have been refuted in another book. Furthermore, the sharns were noted to spend the majority of their time engaged in internal debates and experiments.

Physical Description
Sharns had large bodies shaped like teardrops with amorphous, hairless, and oily black flesh surrounded by a nimbus of purple light. Their massive three thousand-pound (1,360 kg) black and silver bodies were lit by continual magical flares, and they were between twelve and fifteen feet (366–457 cm) tall. They each had three huge, eyeless eel-like heads which only consisted of two nostrils and a large mouth with sharp fangs dripping saliva. All three heads were connected to a single 'trunk'.

Sharns had three large arm-trunks that each ended in three hands. Two arm-trunks were located at the sides of their bodies, and another was attached to their backs, although the ones that appeared in Blackstaff only had two arm-trunks. Each hand had three clawed digits, whereas in Blackstaff, each had four.

Sharns didn't have legs or feet, just a thick tail, and they seemed to prefer to float or fly in the air rather than slither on the ground. Each of their nine hands had multiple eyes that each saw normally with darkvision. In the novel The Sorcerer, each hand had a single eye in the center of its palm. In Blackstaff, their skin could move and shift, with small eyes, fingers, and mouths forming and disappearing at will anywhere on their bodies. They could also regenerate lost limbs within seconds. The sharns could track creatures by scent and by magic.

Sharns could make a noise that sounded like a cross between a mountain lynx and a wounded hare.

History
The first sharns were the surviving citizens of the ancient dark elf and wood elf realm known as Miyeritar. Aryvandaaran historians discovered a familial link between the family of their ruler, Coronal Ivósaar Vyshaan, and the Olrythii, the ruling house of Miyeritar. Circa, the Vyshaanti began negotiating to annex Miyeritar peacefully, but the Miyeritaari resisted. Around, the powerful sun elf realm Aryvandaar began raiding along Miyeritar’s borders and interfering with its trade routes, and around Aryvandaar mounted an all-out invasion of Miyeritar, thus beginning the First Crown War. Circa Aryvandaaran forces had occupied Miyeritar, and by, while the Second Crown War was raging between Ilythiir, Thearnytaar, Eiellûr, Syòrpiir, and Orishaar, Aryvandaar had conquered Miyeritar, ending the First Crown War.

Dark and wood elf clans in Miyeritar continued to resist Aryvandaar, then called the Vyshaantar Empire, and around, during the Third Crown War, Vyshaan high mages produced a terrible magical storm called the Dark Disaster, or the Killing Storms, that hung over Miyeritar for months and laid waste to it, turning it into an infertile wasteland that became known as the High Moor. The fell magic proceeded unopposed because of a Vyshaantar assassination campaign that had killed many Miyeritaari high mages in the months before.

Three grand mages of Miyeritar — T’karon, Hamra, and Alunor — who would become known as the Three Watchers, devised the means to become sharns and transformed themselves and some willing citizens of Miyeritar into sharns in order to preserve their civilization in the hopes that it would one day rise again. The sharns from Miyeritar were the three grand mages and about eighty citizens, which included elves, dwarves, humans, and the guards and scouts of Miyeritar, the centaurs. The elves of Uvaeren also later became sharns. In Mirtul of the Year of the Normiir, the members of the Pentad Retreat also became sharns after the traitorous precept, the vampire wizard Palron Kaeth, used the orcs of the Everhorde to attack their hidden enclave. Survivors of other fallen civilizations had also become sharns over the years, notably from such places as Ammarindar, Ascalhorn, Eaerlann, and Netheril.

In the Year of Many Maws, the first recorded clash between the phaerimms and sharns occurred. In the Year of the Closed Scroll, the sharns finally defeated the phaerimms and imprisoned them behind the Sharn Wall beneath Anauroch, in the Buried Realms, which the phaerimms called the Phaerlin.

Modern Events
The sharns collected items of Miyeritar scattered all across Faerûn for a high magic ritual that would restore the high magic city of Faer'tel'miir, an ancient city of Miyeritar that was located on what is now the High Moor. The last time the sharns had acted with such purpose was when they constructed the Sharn Wall around the phaerimms. Usually, magical fields or internal conflicts among their collective mind made them act unpredictably or madly. On the Feast of the Moon in the, the malignant magic of the Killing Storms was cleansed from the area (the entire High Moor was gradually being cleansed of the corruptive magic, which would take centuries to conclude ), and the Library City of Miyeritar, Faer'tel'miir was restored and renamed Rhymanthiin, the Hidden City of Hope, through a High Magic Ritual.

Among the notable participants in the ritual were the three grand mages, many other sharns and the following:
 * The Chosen of Mystra: Khelben “Blackstaff” Arunsun, Elminster Aumar, Laeral Silverhand, Alustriel Silverhand, and Alvaerele Tasundrym the Silent Chosen.
 * Mentor Wintercloak, one of the Seven Wizards of Myth Drannor.
 * Ualair the Silent, Grand Mage of Myth Drannor, keeper of Uvaeren’s Secrets, and master of the N’Vaelahr of Myth Drannor.
 * High Mage Orjalun of Silverymoon.
 * The elf wizards Darcassan of Windsong Tower and Shalantha Omerdawn.
 * The arcanaweave Jhesiyra Kestellharp.
 * The gnome Parthar the Valiant (also known as Rhymallos the Hidden Eye), an unsung hero of Myth Drannor who took the form of a mezzoloth to infiltrate the Army of Darkness.
 * The wizard Malchor Harpell.
 * Syndra Wands, granddaughter of Khelben.
 * The Tethyrian wizard Lord Gamalon Idogyr, Count of Spellshire, Sage of the Royal Court of Tethyr, and great-grandson of Khelben.
 * Lord Maskar Wands.
 * Phaerl Hawksong
 * Luvon Greencloak.
 * The bronze dragon Essioanawrath the Elder.
 * The gold dragon Tlanchess.
 * The dragon called the Argentalon.
 * The tiefling mage Tulrun of the Tent.
 * The Mistmaster and his consort Azure.
 * The wizards and former members of the Zhentarim, Sememmon and Ashemmi.
 * Maaril, the Dragonmage of Waterdeep.
 * Nain Keenwhistler.
 * Several high-ranking clerics of Oghma: Fourth Reader Shaynara Tullastar of Candlekeep, Loremaster Cadathlyn of the House of Many Tomes, and Sandrew the Wise, lorekeeper high and ranking priest of the Font of Knowledge in Waterdeep.
 * Kyriani Agrivar, half-elf mistress of Selûne’s Smile.
 * Elsura Dauniir.

Khelben and Ualair sacrificed their lives to restore Rhymanthiin, and their spirits went to Arvandor, the elven heaven. Most of the sharns shed their skins, which become a part of the walls of the city, and returned to their original forms.

Some sharns of Miyeritar choose to remain sharns, for they knew that they would become drow if they relinquished their sharn forms (for they were still subject to Corellon's curse laid upon the dark elves). They remained Rhymanthiin’s defenders and worked against corrupt magic in the Realms. They could form from any wall or street of the city to apprehend malefactors due to the sharnstuff woven into the city. All former sharns and those who partook in the ritual were granted a home in the city. The new Rhymanthiin served as a center for magic, knowledge, lore, and the unity of different races, and those with malice in their hearts would not find their way there.
