Valhalla, Hall of the Slain, in Norse mythology is the hall presided over by Odin. This vast hall has five hundred and forty doors. The rafters are spears, the hall is roofed with shields and breast-plates litter the benches. A wolf guards the western door and an eagle hovers over it. It is here that the Valkyries, Odin's messengers and spirits of war, bring half of the heroes that died on the battle fields (the rest go to Freya's hall Folkvang). These heroes, the Einherjar, are prepared in Valhalla for the oncoming battle of Ragnarok. When the battle commences, eight hundred warriors will march shoulder to shoulder out of each door.
Old Norse: Valhöll
