Kvasir
His function depends on which source you read, like many of the Norse god and goddesses. In one myth, he is the wisest of the Vanir and sent to the Aesir as a hostage in a peace making process. In another tradition, he is created when the Aesir and Vanir mix together their spit in a peace making ritual. He is the wisest being. Later on, he is killed by dwarves who make his blood into mead, the mead of poetry.
