In Norse mythology, Valkyries serve drink to the warriors in Valhalla.
Valhalla is Odin's hall for chosen battle-dead warriors, known as the einherjar. In the poetic description of the hall, Valkyries bring ale or mead to the warriors during their feasts. Their role is therefore broader than simply selecting the slain: they also appear as attendants in Odin's hall.
The Valkyries are supernatural female figures connected with battle and the distribution of the dead. Their name is commonly translated as “choosers of the slain,” from Old Norse valr, meaning the slain, and kjósa, meaning to choose. They should not be confused with the Norns, who shape or oversee destiny, or with the disir, a wider category of female supernatural beings. Details vary between poems and prose sources, but the serving role in Valhalla is a well-known feature of the hall's feast imagery.
