Vaettir

Vættir (Old Norse; singular Vættr) or wights are nature spirits in many Norse Traditions.

The Old Norse term vættir and its English cognate wights literally mean 'beings' and relate etymologically to other forms of the verb to be, like was and were. Vættir and wights normally refer to supernatural 'beings', especially landvættir (land spirits), but can refer to any Spirit. By extension, the dead are grouped among the families of Vættir, especially when understood as being in the Underworld (Hel). The term 'families' (ættir) is often translated as 'clans' or 'races'.
