Library of Idoaclese

The Library may be accessed from two halls: one between the thresholds of Trinity and Lambent Flats the other from the hall between the Basin of Stars and the Umbric Plains threshold. The Library contains portals for nine sphered study halls and a gate to the central hub of Threshold Pits. Each sphere hall is a sanctuary and has three rooms: a main hall and two wings. Often histories, art details, and philosophic dissertations are recorded on codii and stored in the study halls.

The Library has a subplane entitled Archive of the Planes, with alcoves containing codices detailing the histories of the Inner Planes and their Houses.
