Eos is one of the main protagonists in The Secret Life of Shifters. She is chosen to become one of the Fundamental Protectors by the Three Goddesses; Iris, Fortanu and Xayni. Back when the Silverclaw pack was in it's prime, she was the head spy and assassin.
Eos is given her powers when she spoke to Giza, goddess of darkness. Her power is fully awakened by Xayni. She can sink into shadows and "swim" through them. She can drag opponents into the shadow, which suffocates them. Using lots of her aura, she can warp enemies to the Lost Zone, as Xayni calls it. Once there, you cannot get back. Her aura is blue.
