Mimir (pronounced "ME-meer"), also spelled as Mímir, is one of the oldest Norse gods, as well as the guardian of the Well of Knowledge. He was beheaded by the Vanir, during their conflict with the Aesir. Afterward, the god Odin carried around Mímir's head and it recited secret knowledge and counsel to him. Hearth and Blitz used to work for Mímir, until being released from their service by Odin.
