If the Belgariad was based on some myth, or the defeat of the Unraveller? I don't know about Torak, but I think the Unraveller's might, considering alot of Fionavar is based on mythology (the two crows, Sorrow and Memory (I think those are their names) are the english names for Odin's two crows, whoose names I do not know). And what is the Wild Hunt, in either Fionavar or the myth in our world?
