Skoll is referenced in Norse mythology and is said to be an offspring of Feneris. However these stories passed down through the ages were incorrect. Fen (Feneris, another of my characters) and Skoll are of the same alpha species and would likely destroy whatever plane of existence they are in should they meet and battle. Thankfully Skoll was moved to a seperate reality by a creature known as Salvo (also mine) several millennia ago. Skoll is a black wolf that emits a red flame like energy at all times and is capable of using this energy in attacks and defense. He can also change the size of his form from a five foot high wolf to a five hundred foot tall wolf, both of which emit the same red energy.
