The Book-Hoard of Jorinnen was a great repository of knowledge and wisdom built in the western Malphigian Basin around 6700 BA by the ancestral peoples of the Old Empires. Stocked with a great accumulation of books and scrolls, it weathered the Seventh Ruin and became a hub of learning in its aftermath.

The complex was lost during the Lanst-Ervuol War and its exact location is uncertain, but scholars believe it was situated near the present-day border of Evenhold and the New Kingdom.
