I actually went to a planet like that while dreaming. In our language, the name translates as Nekron. It was also known as Deadworld because it was basically barren and dessicated, the result of a world war and a viral weapon. Basically, everything that survived became undead. Only, I don't think undead is exactly the word. I mean, they still reproduce. It's just that everything is born looking like a withered corpse, a slimy creature of flesh and bone with no actual skin, or a creature armored in exoskeletal bone projections.

Um... Yeah, that was probably a disturbing look into my subconscious. ^_^;
