Xinlenal

Xinleal was the first ever of the flying netherese enclaves, it was created in -2954 DR by the archmage Ioulaum twenty years after he had first invented the mythallar. The creation of Xinleal led many other powerful mages of Netheril to create flying enclaves of their own, in effect splitting the nation into two, High and Low Netheril.

In -339 DR, the Year of Sundered Webs, Ioulaum suddenly and unnanounced abbandoned his enclave for his lair in the Northdark. The sudden dissappearence of their great champion caused wide-spread panic in Netheril, leading up the casting of Karsus's Avatar and the end of the Empire of Magic.
