Who is the All-Father and king of the Norse gods?

The story behind the answer

Odin is the All-Father—the ruler of the Aesir and king of the Norse gods—presiding from Asgard. Known for wisdom, war, and poetry, he’s a relentless seeker of knowledge: he sacrificed one eye for a drink from Mimir’s well and hung on the World Tree, Yggdrasil, for nine nights to gain the runes. He’s accompanied by ravens Huginn and Muninn and commands the Valkyries who choose the slain.

To sort the options: Thor is the thunderer and protector, Loki the trickster, and Balder the radiant god whose death portends Ragnarök. Memory tip: “Odin oversees, Thor thunders, Loki lies, Balder beams.” One-eyed All-Father = Odin.
