Gods and beings

A Old Norse mythology knows two families of gods, Æsir and Vanir, who, after a war described in Völuspá 21-24, live at peace through mutual hostages (Njörðr and his children among the Æsir; Mímir and Hœnir among the Vanir, per Ynglinga saga 4). Alongside them stand the jötnar (giants), dwarves, light- and dark-elves, and mythic beings including the norns, valkyries, Fenrir, Jörmungandr, and Hel. The taxonomy follows chiefly Snorri's Gylfaginning.
