I'm particuraly intrested and am happy to express it i have two real ideas that work well.

The first being a alchemist/enchanter characte master of material magic and all that which is simple.all about the tricky

The second is a witch who made a contract with a demon/imp at around 11 and still looks like that. It's a funny quirk per say as they actually constantly act like a adult. vashneer her shadow/imp/demon is used to fight and is actually whatd be a parasite to most is completely symbioitic for her.

She would probably have a huge amount of one magic, but be completely sealed off from another as vashneer leaches it all. The key feel here with the character is symbiosis the two need eachother to overcome short comings. 



Both characters have eqaul depth the second just takes more explanation.

EDIT
I made this in a rush so probably going to edit it. If you see it and have questions just ask.

Also i can change both characters to change the needso f the r-p/combine them as well.
