Ithunzi

The Ithunzi, also known as the Shadowmen at first contact with the Charon Dominion and Rockmen by the galaxy of realspace during the Extant War, were a vassal race of the Charon, following the Oblivion Crusades, and were among the few species that were not only able to combat the Charon onslaught, but were also inducted into the Charon following their subjugation.

Mineral-based lifeforms of bio-obsidian composition, the Ithunzi are technologically predisposed, aggressive combatants, possess remarkable regenerative capabilities, are immune to aging, and have such trace organic elements in their biological make-up, they are able to survive in nearly any environment, such as the vacuum of space, and are undetectable by lifeform sensors.
