Electronos

The Electronos are a human-parallel species of electronic beings that naturally evolved on Cytens. Cytens is similar to Earth in most respects with the exception of all lifeforms evolving to be electronic and mechanical. It is likely that even primordial life was electronic due to the high dissolved metal and silicon content of the oceans made up of stoysum. Evolution in the ocean was going steady, even as far as borderline sentient life developing around the Cathoric Plateau. A large interplanetary asteroid hit Cytens near the Fushign Trench which introduced a surge of organic materials that then reacted and dissolved in the oceans. Due to the nature of life on Cytens the organic materials started to quickly corrode through the metallic skin of the creatures living there, swiftly killing all life that wasn't adapted or couldn't reach shore. Around 65% of all species went extinct in that event, but it only made the survivors stronger. A good portion of the shore life moved on to adapt in a non-stoysum environment where there were much less organics. From there they followed the general path of evolution all the way to the Electronos.

In their history the Electronos had several visits from the Deletaurs who found them by mistake when a space probe of theirs was knocked off course and crashed into Cytens.
