I always figured that the nomen were from Borallus, the place Yuri wanted the fleet to go before they chose Carilon. Maga described Their home as "the land of the mega sun and endless sands".

I think the Nomen may be a sect among the Borellians, meaning that the Nomen are Borellians, but not all Borellians are Nomen.
