R'lyeh: Endless Night

Well, technically, the Enslave Mind ability for them just represents their memory of that particular unit, which they can then recreate. So it's not actual enslavement-the original gets disintegrated-it just duplicates the effect

They then use the duplicate to study-to better learn the ways of their enemies-and to fight against their enemies/serve the Aboleth cause.

May I suggest Aboleths 'touched' by the Hungry Void alluded to in the title? If the Aboleths' growth can be altered by a single god, then a poorly-developed Aboleth who touches a practically endless field of raw magical (or pseudomagical) energy will surely exhibit some strange development. The question, I think, is whether a 'Void-touched' Aboleth would be a recruitable unit/commander, a summonable unit (possibly representing purposefully making young Aboleths access the void?), or a hero (I'd guess a magical prodigy who learned to access the Hungry Void far before most). Any could work, really.

EDIT: If you haven't already planned on including something like this, of course.
