I've got a situation where I need a name for a group of humans who cannot feel any pain or emotion (Kinda like CIPA, but without emotion as well). These have been stripped off them by a supernatural creature (that I've named Lamia, after the Greek myth, who in my world is the first Succubus - I know that many consider Lilith as the first but I want to stay away from that path)
Basically these humans then follow Lamia and guard her. They do not sleep, they do not feel, they keep going until their heart stops. They push their bodies beyond their limits (so super strength, speed, etc.) I'm stumped with coming up with a name for these people and don't want to use anything contemporary. I'd prefer something out of myth but I haven't been able to find anything similar (Most monsters and beast are exactly the opposite - reflecting the base emotions of humans)
I'm not asking what they would do or what they would be like (I already know) I'm just stumped in what to call them. They only appear in one story and are basically cannon fodder.
If anyone knows of any creature from any mythological pantheon that fits the bill, that'll be a great help!
