Toxic waters.

Bio is no normal werewolf. She's a rare breed of toxin infested wolfs, the bad thing? Vampires created toxic wolfs! Toxic wolfs are immortal at the age of 26, the only way a toxic wolf can be made is if a toxic wolf passes a normal infant werewolf spreading the toxin. At the age of 16 a toxic wolf will shift. Toxic wolfs have no mates, unless born of werewolf. Toxic wolves have no 'inner wolf'.

Bio had just turned 16 when her pack heard of this they banished her. She fled, fled to a place called, White Water.
