Chisandre

She's a young and intelligent witch who wants to help Princess Aluryn take back her throne. She can speed and slow the flow of time, but it takes much of her concentration and is only used to dire situations. She apprenticed under the High Witch in her village. Chisandra is very defensive of her mentor and will lose her collected nature in an instant if he is brought up. No one in the group is really sure why she's so touchy about it. 

Currently, she has a demon from the Crystal Dunes bound to her. She didn't entirely think her decision through, however, and highly regrets her actions since the demon follows her day and night. Chisandra knows no peace from the demon who never sleeps- plus, all his jokes are really bad.
