His kind was though to be extinct by most, yet they remained in a kind of exile from the events and politics of the recent stages of interstellar history.
Unlike many of the space-faring species, they welcomed and embraced the emerging and slowly spreading ascended biology, the great step of evolution allowing the usage of now abundantly available advanced materials and technologies, within -and expanding the- framework of the highly adaptive system of biology.
They still use external armor as an additional option for combat preparation, although creatures of ascended biology are naturally very durable, along with redundancies and regenerative capabilities.
Thier internal organs include power generating ones for their flight-assisting gravitational distorters (visible in their wing limbs) and also to allow them to recharge their weapons and other devices with energy from their own bodies, although this comes at the cost of seemingly supernatural hunger.

Their return was seen as a kind of miracle in the harsh-fated, oppression- and poverty-ridden outer colonies of a long collapsed galaxy-spanning civilization.
