Zethai

The Zethai are automatons made from organic and inorganic material. instead of a brain and a heart, they have a gelatinous core that controls the rest of the body. they are extremely durable, being made of a magical 'live' metal alloy that only they are capable of producing, and differ slightly in appearance depending on their purpose.

History
They are the last vestige of a long-extinct race that once lived in aloris. After a cataclysm and the consequent collapse of their society, they took shelter in bunkers of varying size and purpose, the biggest bunkers being connected to each other, and they were where the most intelligent resided, tasked with the mission of guaranteing the survival of the species. As time passed and the conditions worsened, they resorted to experimenting on themselves. the result was creatures distinct from their ancestors, created artificially through genetic manipulation. The original species didn't survive, but their culture, their exploits and achievements, all of that would through the new ones, and one day the world would be ready to be inhabited again.

but it didn't. they underestimated how long it would take. the machines eroded over time, their sensors broke, mechanisms failed and the zethai, mostly unaware of their situation, remain inert indefinitely.
