World of my head

So this is kind of a test run to see if I should turn this into a book so in this world there are fairies / spirits they live in a separate dimension away from humans because if humans get a hold of their power they can cure any disease get rid of pollution just with their blood. The spirit types our water air fire darkness light and dimension being the extinct and only one who can make another world any young spirit being human origin or spirit origin go to the school Sufell where they learn to control their powers they can go at any age but they have to go otherwise they could lose control and really hurt people I'm not going to throw my actual characters in here this is a test run, you can be any spirit type and you are going to Sufell for the first time One more thing people at Sue fell tend to go missing The real reason for this is the headmaster who is a corrupt psychopath but we don't talk about that you can add that into the story if you want also there are two different types of jobs you can train to be in sufell an elite or a fallen both have their places in society and both are really powerful but the elite train to be guards fighters while the fallen trying to be healers and other such things(do not use voice)
