Arcanum is the largest and greatest school of magic of the Elder vyes. It is one of five schools created by the vyes, and it is inhabited by the Raszna. It is a domed cavern that is miles across; it is about as large as Old College at Rowan. It is lit by luminescent fungi and has waterfalls that cascade from its walls, flowing into several lakes and a large river. Prior to the entry of Max McDaniels and Connor Lynch, no one from Rowan or Solas had entered Arcanum.
