Einherjar

According to Snorri, the Einherjar were the slain warriors chosen by the Valkyries. The Valkyries brought one half to Valhalla and the other half to Folkvang.

In Valhalla, the Einherjar drank and fought till the end of the world.
At Ragnarok they'll fight at Odin's site against Loki and the giants.
