The Ethereal Academy's building is ancient, carved into the side of a mountain hundreds or even thousands of years ago. There are five levels, and below and around them are networks of caves, some of which have been mapped and explored. New students are often hazed by being sent into the tunnels to find a chunk of crystal or a subterranean creature, briefed beforehand with legends of students who wandered in and never came out. The entire place is heated and lit by an acidic, luminescent mineral fluid pumped from the Cave of Bubbling Pools, all machinery powered by the Energy students.
