The Black Library

The Black Library is the Harlequin fortress-archive hidden in the Webway, the Eldar repository of forbidden lore that this map files as a station under the Exodus Worlds. It is not a planet, not a fleet in Ultima, and not a Black Library publishing imprint.

Solitaires, masques, and desperate farseers come here for books that can unmake a soul. Cegorach's servants keep the doors. Imperial charts that plot a pin at all are already lying about coordinates; the Webway does not sit still for Jambonium XY.

The Black Library still matters as the Webway archive every other Eldar story eventually name-drops. Unofficial summaries keep the exodus-worlds parent and kind=station, and they refuse to treat the row as a craftworld or as a Segmentum Ultima dockyard.
