[Eon's POV: ]
Artificial helpers, or in simpler terms, artificial-intelligence-powered lifeforms programmed and created through the help of magic, magic engineering, and alchemy of this world, and the technical knowledge of my previous world.
They were fundamentally different from the usual helpers in the academy or the purely magic and alchemy-based artificial creatures like the Keepers.
They had a detailed program running them and instead of only a magic ore powering them, there was a sophisticated heart created to function like an actual heart.
And this heart was also different from a golem's core.
It wasn't their weakness but rather a core strength that regulated the power throughout their entire body and maintained the 'Axiostasis' a term master gave this process that very closely resembled the homeostasis of a mortal's body.
