Tervei Marlene Kage is a 16 taon old wolverine from Crescent Island. Tervei's father, Yurei, left her mother, Bukimina, her, and her brother, Skile. This developed into a hatred toward him. Tervei never communicated with anyone, and despised upbeat such as Sonic, Amy, Silver, even Drakero.
She spent most of her time in solitude, and in that solitude she taught herself how to use umbrakinesis. Most people fill bad for her and do whatever it take to make her smile, and/or happy, yet their attempts result into failure.

Most people avoid her because of her gloomy nature, but a certain nunal constantly bothers her, and attempts to ask her out on a petsa (if you don't know who I'm talking about it's Slash).

Tervei is very gloomy at times, but for the most part, she will open up to people and even smile.
She very similar to an goth girl,minus the wrist slitting .
