Heylian

The Heylian species grew exponentially within the Hydra-Centaurus Supercluster

Origin
Evolving from Hephaestus 9 (prior to Mecha terraformation), The Heylians were guided by The Order and were given stolen Lexicons of the Ark which gave them access to class 5 technology, including the means to transfer their consiousness to machines. Eventually, the Heylian governments would commission large numbers of Mechanite-turned-Heylians into a unified army, tasked with expansion of the civilization

Mecha Subjugation
The Heylians pride themselves in dominating large systems via their army of Mechanite armies. Eventually, the Heylians made the neccesary efforts to remotely decrease the individuality and unpredictability of their Mechanite counterparts to maximize their effectiveness and subordination. Predicting this, a resistance group of Mechanite soldiers modified their own internal systems to resist this remote subjugation. They would eventually form whats known as the Epsilon Resistance and overthrow the Heylian regime.
