- n.pl. In German mythology, the children of the mist, a race of dwarfs or demonic beings, the original possessors of the famous hoard and ring won by Siegfrid; also, the Burgundian kings in the Nibelungenlied.
Sorry, no etymologies found.
The dwarfs, or nibelungs, are black uncouth pigmies, hating the good, hating the gods; they are crafty and cunning, and dwell in the bowels of the earth.
I guess the SciFi Channel didn’t trust its audience to watch anything with “nibelungs” in the title.
