Oh definitely it's the dark God the warlocks make a deal with, Nyx. Not Wyrd.
With fetch, it's a different situation entirely. We know they are alien to the Myth World, and that they wear the skins of women. But do we know that they really die immediately after we pummel them with arrows? I don't think we do. My take is that arrows and sword slashes tear their morbid "clothing" apart to the point that the alien, in essence a chaotic energy, is lost to space, where it dissipates uncontrollably.
They didn't make a deal with dark powers to be on the Myth World. They were trapped there, and hoped that by assisting The Dark, Balor's promise to return them to their native world would be kept.
