Shade

Shaderi "Shade" Silverwind is the silent magician of the StarLight Rogues. She is well practiced in the dark arts, easily able to manipulate black energy with her bare hands, but uses her staff as both a focus and a restraint. Due to being half-shadow, half-human, it was only half a surprise when she found that she was Shaden's half-sister (the Dark Lord who created Shaden to follow Ender also had a relationship with a human mage, and Shade was their only offspring, due to her mother being immediately destroyed by the Dark Master). She somehow appeared from an alternate dimension, and can also harness stronger magic by discarding her staff. However, doing so also has the chance for her to become possessed and kill the people that she loves, at least until she retrieves the staff. It's almost as if it's happened before...
