Skol and Hati

Legends tell of a fierce battle that once took place between the siblings Fenrir and Garm. The aftermath left their flesh strewn about, flesh that would grow and morph into the children of the two siblings. These were the origins of the wolves Skol and Hati. Initially they were cute adorable pets of the Aesir but soon were trained to become Wotan's personal guard dogs. Under Wotan's training, they became both fierce and wise but most importantly loyal. When Wotan discovered the prophecy of Ragnarok he saw the two wolves devouring the sun and moon. To ensure the prophecy would lean into his favor he did not bind the wolves like he did the the rest of their kin, instead he kept them loyal for if he controls when Ragnarok happens it will be ever more in his favor. 
Depiction. Skol appears as an all white wolf with blue runes etched into them while Hati appears as an all black wolf with red runes etched into them.
Worshippers. Guards and all kinds of folk dedicated to protecting something revere the wolf twins in one way or another. They are also popular among those who dedicate their worship to Wotan. Werewolves also worship them as well.
