Desks as dungeon furniture: they can store items like a container, and acts like a table if you are on top of it (if levitating you can interact with it and things on it). Sometimes generates a magic marker inside. Writing scrolls or spellbooks at a desk has some bonus: maybe a higher chance of writing unidentified, or a slightly reduced or capped ink cost. Possibly put one or more in the College of Archaeology, and Warden Arianna’s office for Convicts.
