T'vaoan (Earth-5875)

T'vaoans (Latin Perosus latrunculus cotes, meaning "hateful bandit of the rocks"), known to humans as Skirmishers, are a race of kig-yar from the asteroid colony T'vao. Alongside their ruuhtian and ibie'shan brethren, they served in the Covenant in specialized roles. They suffered massive losses during the First Contact War, with two-percent of their population dying during the Fall of Reach.

Origins
The t'vaoan precursors originated from Eayn, the homeworld of kig-yar, during the initial years of the species' space colonization through the Y'Deio system. After the colonization of the asteroid T'vao, its colonists would gain drastic phenotypical changes during the next centuries. The higher gravity, harsh environmental conditions and drastic atmospheric shifts led to the t'vaoans evolving drastically different from those who lived in Eayn. After the kig-yar were inducted into the Covenant, the t'vaoans followed.
