Mimir is a deity in the Norse pantheon. A giant of the Aesir gods, he was beheaded by the Vanir. Odin restored the head to life with magic, and placed it in the Well of Mimir.
Appearance and personality
Honir is the disembodied head of an ancient giant, with a long white beard. He is 2½ feet in diamater, and travels by slow levitation.
Mimir is a spellcaster of superhuman ability, and can cast arcane spells without material or somatic components. He can also lift objects with telekinesis and has multiple unseen servants to do his bidding.
Mimir is the wisest of the Aesir.
Mimir is a god of knowledge, wisdom, and inland waters.
While the people of Midgard typically worship the Norse pantheon as a collective group, Mimir is particularly followed by all those who seek knowledge. He is popular among sages, wizards, and illusionists. They tend to be themselves lawful good in alignment, though this is not always the case.
Temples of Mimir have large libraries, and often double as universities.
Mimir's holy symbol is a pool of water.
Mimir's favored weapon is unknown.
Mimir has no known familial relations to the rest of the Aesir.
Mimir's enemies are unknown.
Mimir guards the Well of Mimir. Anyone who drinks from it gains increased wisdom, but must make a sacrifice of equal value in payment. It is said to be guarded by a beholder formed by Mimir's severed head.
Mimir possesses Odin's eye, and with it can scry the universe as if it were a crystal ball.
The wise giant Mimir and Odin's brother Honir were sent to Asgard to Vanaheim in a hostage exchange in order to secure a peace treaty. At first, the Vanir judged Honir to be handsome, wise, and a strong ruler. However, they soon discovered that they had been misled, as Honir lacked confidence in his answers without Mimir's counsel.
The Vanir were outraged, but dared not kill Honir for fear of angering his brother, Odin. They instead cut off Mimir's head, and sent it back to Odin. Odin used various spells to return the head to life, and Mimir returned to his well to live.
