The Echo is powered by the soul.

It also usually grants a type of Omni-Linguisum.

Tempering isn't just Brainwashing or it could be resisted and broken by strong willed people. Tempering is binding someone's soul and to a primal, that's logical since Echo usuers are 100℅ immune to tempering as are artificial mechines who don't have them at all.

And the reploids I mentioned are Bio;Mecnical SENTIENT Machines who achived self awareness.
Bio-Mechanical means they could potentially manipulate aether, and Sentience + Self Awareness is the foundation of a soul. So Clockworks can NOT have the Echo, they are programed Machines with no aetheric connection.
