Odin, the father of gods, is the head of the Aesir and rules from Asgard, where his hall Valhall is located.
His constant companions, the ravens Hugin (thought) and Hunin (memory), keep him up to date with any information they learn during their exploratory flights. He also has 2 wolves at his side, Geri and Freki.
His proud warhorse is called Sleipnir, which Loki gave him as a gift. His powerful weapon, a spear (which never misses its target) is called Gungnir.
