She is a dino-mammit (mammits are animal people)

Yin is the new leader of a group called Sorcerer Weilders. She posseses a Sorcerers Artifact called "Time Band" a little wrist band she wears that can change the flow of time for her or anyone else. She can move really fast and have everything move in slower motions or have her enemies see the world too slow or fast. Mainly alter time but she can't go back in time before her present timeline, she can, however travel as far into the future as she wants. Naturally, she's old, but uses her Time Band to keep herself young. Naturally, she is very strong and does mix martial arts for her combat, her kicks are her most deadliest attacks.

Yin has temporary-short-term-memory which she needs to take medicine to keep her memory from fading. She has this condition from an attack by Marques's men when a knight on horseback had his horse catch her by surprise and kick her head with all four hooves, running her over.

She acts like a smartass, has humor, and doesn't like Jaimus.

Her original accent was meant to be Jamaican, but I'm leaving accent open to "any" to see what ideas you might have for her voice.
