Sarah

4'9" tall, despite being 35 years old and owning a cabaret, she's often mistaken for a very young adult at best or a teenager at worst.
Her aging process froze after being touched by a flow of magic, something she truely despises and tries to compensate it with an acute sense of fashion and mature language and behaviour.
Saying anything about her young appearance is similar to a deathwish.

Her powers have but one limitation: she can't harm others' fate.
