Well... unknown, all we know is that because of the way Ainz built his build in pseudo-necromancer fashion he unlocked Eclipse for him self, and as far as we know he's the only carrier of that 'title', and might have been in whole of Yggdrasil considering how tightly information is shared around.

Overlords as mob race(or I suppose evolution if you're a player) seems to be quite known, with at least 3 types for general areas, "In YGGDRASIL, there were several types of monsters in the Overlord family: the Overlord Wiseman, which was skilled in magic, the Overlord Kronos Master, which could use time-related skills, the Overlord General, which was adept at controlling armies of the undead, among others. Even the weakest of those was at least level 80. "

 So it shouldn't be out of the question that it was more less widely known type of undead in Yggdrasil and that it didn't need a death/necromancy oriented build to be able to get it/unlock it.

 Even though Ainz with Dark Wisdom should pretty much be a general mage by now, since he basically has every buff/support spell available(3000~ spells/abilities was total count in the game right?).
