This is Ethan. He's the son of a dark fairy mother and a nature elf father. He lived happily with his father in an elf village until the age of 12, when an incident happened in which he ended up nearly killing one of his friends. Since his mother is a dark fairy, he can use dark magic, although if he uses it for too long, it takes him over and he becomes "Dark Ethan." In his dark form, he can't control his actions, and it often ends up badly. Everyone in his village understood that the incident wasn't his fault, but they decided that Ethan was too dangerous, so they exiled him. He wandered around for 5 years, moving around and living in many different places. One day, a now 17 year old Ethan found Kai wandering around the forest he was currently living in. Kai didn't know anything about themself other than their own name. Ethan was the first person they encountered. Now Kai and Ethan travel together, having adventures and looking for somewhere to live.
