Heroes of Midhgardhur
Mimir (“The Rememberer”) was once one of the Aesir, but he was given as a hostage to the Vanir. At one time, when the Vanir suspected treachery on the part of the Aesir, so they seized Mimir and beheaded him. But Odhinn was unwilling to lose such a great counselor and source of wisdom, so he took Mimir’s head and embalmed it, using magical herbs and chants and charms, then placed it in secret at a well at the roots of the world-tree, Yggdrasill. From here, Mimir’s head absorbed all the worldly wisdom of the Nine Worlds, and speaks its knowledge and wisdom to Odhinn.
