From ROI Wiki

The Benoi are a xenopoid species that are made of living energy, and live in the space between universes, inside the dimensional divide; a realm of pure energy. They are generally very benevolent and pacifistic, while at the same time curious and inquisitive, always seeking to know more and learn as much as they can. They also employ an odd form of marriage, with the two lifeforms joining together to become one unique lifeform with two distinct personalities within, one being dominant, the other subservient. Usually the stronger of the two within the union become the dominant personality once bonded. Like so many other species in the galaxy, the Benoi are a creation of The Weavers, who eventually became sentient and self aware under their watch, before breaking away from them and eventually setting off on their own.
