The Black Dragon Library is a compendium of lore regarding the known history of the world. Initially assembled under the direction of Archmage Elfriede Simbledon at the Black Dragon Guildhall at Last Rest in Year 1 of the New Era, following the Guildhall's destruction in Nighthal NE 1, it was reassembled by the Archmage at the Black Tower in the Spring of NE 2 during the War for Greenskin Plains, only to be destroyed yet again in Ches NE 2 in the Fall of the Black Tower and painstakingly reassembled by Simbledon and his new apprentice, Emelyn, over the course of the next months and years in its original location at a restored Black Dragon Guildhall in Last Rest.
