Endless Athenaeum

The Endless Athenaeum is a secret realm in an undisclosed plane. It is an embodiment of the goddess Ioun, the Knowing Mistress.
The Athenaeum is a dimly lit, Escher-esque, infinite library containing records of all that is known, tended and read by Ioun's spectral, celestial servants. Stories of every life, from birth to death, exist as books written in various languages; near an entrance and near the center, the books are written in Celestial; a little farther out are some written in Abyssal. The bookshelves, which move on their own to rearrange themselves, are made of different materials: various woods, metals, and so on.
The realm is well hidden, as Ioun is still nursing a grievous wound dealt by Tharizdun during the The Calamity and knows her enemies seek to finish her off. A Plane Shift to the Athenaeum takes noticeably longer than the spell usually does.
