The Dark Elves (known as Svartálfar by the Ancient Norse, Älfeneel or Harudheeniksel by the Dark Elves themselves) are among the oldest known species in existence, hailing from the realm Svartalfheim. They are one of the mortal enemies of the Asgardians, the other being the Frost Giants. Some members of their race have been shown to have the fortitude to wield an Infinity Stone. They are now presumed to be critically endangered as a species or even extinct.
