http://norse-mythology.org/skoll-hati/Skoll (pronounced roughly “SKOHL”; Old Norse Sköll, “One Who Mocks”) and Hati (pronounced “HAHT-ee”; Old Norse Hati, “One Who Hates”) are two wolves who are only mentioned in passing references that have to do with their pursuing Sol and Mani, the sun and moon, through the sky in hopes of devouring them. At Ragnarok, the downfall of the cosmos, they catch their prey as the sky and earth darken and collapse.
