Fancy Bastard Scales of War
Rather than defend her seal with angelic steel as Pelor chose to do or with the weight of civilization as Erathis did, Ioun hid hers away within the Sealed Library, a marvelous construction which is itself hidden in the fabric of the domain. Within its confines, trusted scholars have long worked on sensitive projects for their lady while standing vigil over the seal.
The open and well lit interior seems at odds with its cloistered nature, but the structure of the place is designed to promote contemplation while fostering research and advancement. The vast shelves could never contain the sheer quantity of lore required by the scholars ensconced within the library. They are tied through ancient ritual to every library that welcomes Ioun’s presence. Books slip from the world and beyond to stock the shelves of the library before shifting back when no one is watching.
