The Black library is a collection of tomes and treatises on magic. Rumor claim that it focuses on necromancy, demon-summoning, and other subjects of death and destruction.
Arcane Whitemist controlled the Black Library until her death in April 508. The Library is located in the Luminal's former keep of Duzen Iken in southern Hanist. Duzen Iken surrounds an improbably steep-sided hill or mesa, topped with a copse of trees. Arcane's villa is on top of the hill, and the Black Library is within the villa.
The Black Library is a now a major research site into basic thaumotology for The Liberation.
