Tribe descended from the Council of Survivors after the war that destroyed Xenon's civilisation. The Hommiks appeared to be almost entirely male, and relied on capturing the Seska to supply them with wives and hence sons: daughters were left on the hillsides, and some were found by the Seska. Those near Dorian's base were under the rule of Gunn-Sar. There may or may not have been others elsewhere on the planet. After Gunn-Sar's death, Nina vowed to lead the Hommiks away to a new home.
Pella told Avon that the Hommiks reverted to primitive tribalism "centuries ago". Cato referred to a council that could apparently challenge Gunn-Sar's authority.
