The Spiritual Academy is not well known around the Empire. It was created barely 100 years ago and is focused on a system different from those already known.
They do not use swords or any external tools except Magical Artifacts, and they have almost no attack magic. Instead, they focus on researching the Spirit World and the entities that come from there.
They also have their own magical artifacts to summon beings from that world, so they can have more than one. But this Academy's research has just started and is still in its early stages. Although they manage to summon and teach the students how to do it, they still have more goals in mind.
Some of their research is known to all, including the summoning of more powerful spirits, the use of mana, and how to access the Spirit World. But since they are just in the initial phase, so many ignore them.
