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.
The school weapon is shuriken.
The Ethereal Academy may well be the oldest surviving Ninja Academy. Its students and Senseis can be traced back to the time of Ghengis Khan, and thus legends and myths abound.
The original school was based around the five senses, and exclusively male, but Smell and Taste were first blended, then abandoned. Sight developed into Empathy (seeing the emotions rather than the physical), and Touch into Gravity.
During Lothor's worldwide attacks on ninja academies, the Ethereal Academy was taken by General Tauza. Three students managed to escape, but in the process the mountainside was demolished by the attacking forces. After many battles, the captive students and teachers were rescued and the space ninjas defeated.
