Hey, thanks for the tips and feedback mate really apreciate it
I gave his story some more thinking.
Grubb and his bandits lived in a fantasy world torn by a war between two major countries. One of them ruled by an evil imperialist dictator (and wizard). They didn't take part in the war and instead laid low in an isolated forest getting by by robbing travelers and passers. At some point the evil dictator tried to recruit them. He offered them magic fire powers and in exchange they would side with his forces in the war. Grubb made the call to accept the deal out of greed. Though they enjoyed a honeymoon period with their new powers soon they started feeling corrupted and missed their old way of life. Their appearance even changed and they turned a purple color (originally light grey-blue) and got scruffier. Uncomfortable with some of the missions they have to execute, Grubb needs to go on a big redemption arc and find a way to break the bond and free himself and his men.
wow, that's the longest I've ever written, hope I didnt bore anyone to death
