Arthur Rackham, The Giants Fasolt and Fafnir Seizing Freia, 1910
Freyja receives the slain heroes of the battlefield quite respectfully as Óðinn does. Her house is called Sessrumnir, 'filled with many seats', and it probably fills the same function as Valhöll, 'the hall of the slain', where the warriors eat and drink beer after the fighting. Still, we must ask why there are two heroic paradises in the Old Norse View of afterlife. It might possibly be a consequence of different forms of initiation of warriors, where one part seemed to have belonged to Óðinn and the other to Freyja. These examples indicate that Freyja was a war-goddess, and she even appears as a valkyrie, literally 'the one who chooses the slain.'
