Near the end of the Second War, the black dragon Deathwing travelled through the Dark Portal to Draenor. Believing the world to be a relatively safe haven for his offspring, he secreted away a cache of black dragon eggs. Following the war, Ner’zhul recklessly opened multiple portals on Draenor, and the magical stress tore the planet apart. The energies released in this catastrophe altered Deathwing’s eggs, resulting in the Nether Drakes partially corporeal and partially ethereal dragons who possess the ability to shift between the astral and physical planes. Without Deathwing’s guidance, these otherworldly nether drakes are just now finding their own way among the blasted ruins of Outland. They are black, somewhat translucent, and have a glowing aura around them.
