Cyroc

Overview
The Cyroc (SY-rock) are a biomechanical species indigenous to the planet Dyrexus (dye-REX-us), known for distinctive face-concealing masks that they rarely remove in front of others, which in the case of offworld cyroc are often fashioned after the dominant species of whatever planet on which they've settled.

Believed to have been primarily biological at some point in their history, the cyroc extensively modified their bodies to survive on a home planet gradually rendered near-barren by excessive industrialization and pollution. As a result of this, many cyroc have departed via colony ships for other worlds, on which they often adopt outwardly primitive hunter-gatherer lifestyles to live in relative harmony with their natural environments.
