"Skoll chases the sun, while Hati prefers the moon. Because Neotellus has three moons, Skoll set her sights on a piece of the lunar spoils as well. While the two are far from comrades, they make a terrible twesome* of moon devourers."
Skoll and Hati are two giant wolves from Norse mythology said to chase the sun and moon. The cycles of day and night and summer/winter soltices correspond to the wolves' pursuit of the celestial bodies. They devour the moon and sun at ragnorok.
