As with Adam Eternum, the Alliance's Arathi Basin battlemaster in Shattrath, Keldor the Lost is a real-world reference to the animated series He-Man and the Masters of the Universe. "Keldor" was the identity of He-Man's arch-nemesis, prior to his transformation into the evil Skeletor. Being undead, Keldor the Lost's hood, glowing eyes, dark blue attire, and skull-tipped staff all bear a striking resemblance to Skeletor. In addition, he will even cackle when you finish speaking to him.

"I have travelled far in my search of a way to ultimately defeat the League of Arathor in the Arathi Basin, but that Lion-clothed lummox, Adam Eternum hounds my every move! Still, if slayers like you would return to Azeroth, perhaps we could defeat the Alliance once and for all!"
