Think: Norse zombie. That's a draug.
Erik the Red would have rhymed it with Smaug. Modern Icelanders say DROIG. Take your pick.
However you say it, a draug is a nasty critter, called in Translation-ese a revenant: the walking undead. Draugs are creepy, immensely strong, and—already being dead—immensely difficult to kill.
(So far as we know, the Old English weren't familiar with the concept; if they were, it didn't manage to get into the literature. But, if they had been, through the miracle of modern linguistics, we can say that Anglophones would today know the creature as a drow [rhymes with plow].)
Etymologically speaking, the word is connected to drag. Whether this is because the draug is basically a corpse dragging itself around, or because it drags its victims off, is unclear.
But it does open the door to some delicious possibilities.
