Library of Lore
From Syra D&D Wiki
This imposing citadel sits atop a barren bluff in the plane of Outlands. Those who would access the library and its knowledge must climb a single narrow stair guarded by four elder elementals, one of each of the cardinal types. It was formerly the home of Boccob, but is now ruled by his successor, Ioun.
The walls themselves are proof against teleportation and astral meddling, and those who try find themselves at the base of the great stair. Within the walls of the library, spells that access other planes do not function. The library is a convoluted mazework of passages that cross beneath and occasionally through each other, leaving no mark of their passage but foiling the most diligent of mapmakers. Within this structure are private meditation cells for spellcasters, sealed armories of magic items, and both true and false libraries that contain much of the magical and mundane knowledge of the multiverse. Those granted access to a true library (done with the approval of Ioun herself) can find the answer to any questions as if a commune spell were cast. One hour of research is required for each question answered. The Library of Lore contains a copy of every nonartifact magic item created by mortal hands. They are sealed beneath magical wards and traps, and golems and shield guardians patrol the halls. Souls who worshiped Boccob and Ioun in life may peer over their patron's shoulders, catching glimpses of the secrets of the multiverse.
Ioun is a greater power, and as such the effects of her realm can be felt far beyond the walls of her library. Within this area she can limit magic of many types at will. In addition, much magic is enhanced in Ioun's realm. Divinations cast within the domain are extended, and all spells within the Library of Lore itself may be cast without verbal utterances. She has the power to further modify the magic trait of her realm.
The souls of Boccob and Ioun's worshipers appear as they did in life and have abilities typical to Outlandish petitioners. In addition, they have the ability to know the motivations of others and they often use this ability to determine whether a visitor deserves to receive the information desired. Petitioners are usually librarians, scribes, researchers, inventors, or guides.
