This is Pan, he was once the book keeper and duster for a great and powerful wizard. With the wizards disappearance and then untimely death, Pan was left with the man's domain along with all of his belongings. While working for the wizard Pan was told multiple times that he had even less affinity towards magic than other beast-class beings, and that it would be useless for him to be taught. But that didn't stop Pan from following in his employers footsteps and following his passion. He ran the magic shop selling sub-par charms and small spells until he had no other choice but to sell the shop and his home as he stood no chance against the other professional magic vendors and relocated himself and some of his books to the woods. Pan stubbornly practiced against his masters words and eventually gained quite a bit of skill. When the magic ban was issued across the kingdom Pan hid his books and robes in order to avoid being imprisoned or executed. (Not that many had any suspicions about some wood rabbit having magical abilities to begin with.) He now spends his time quietly living in his cabin in the woods practicing small spells to help him live out his days. Occasionally some travelers in need would find their way to his cabin and he'd assist them with healing or navigation spells if he deemed they were necessary. His most notable encounter was with the prince of all people!

Pan's doubt in himself and his skills might be what's preventing him from casting larger spells. Maybe a quest with some adventurers would get his nose out of his books and open him up.

And there we go.
I've been playing Dark Cloud 2 so, this is very much inspired by the games art and character.
(lol, his book is like a blue Clow book, I'm so original pffft.)

I NEED A RABBIT CHARACTER. RABBITS ARE THE BEST AND I DIDN'T HAVE ONE, SO NOW I DO.
Maybe I'll add more info on beast-class beings and stuff later too.
