Borays are boar-like sentient creatures that inhabit the planet Sectar.
While the Borays originally were an agrarian race, they find that it is easier to take what they wish from the humans at the Serenity settlement during full moons, rather than raising the crops themselves.
In addition, the Colonies knew of the Borays, despite the social and economical disconnect between the Colonies and Sectar. It is quite likely they are the origin for the negative saying, "borays of humanity", which is used to describe the denizens of the freighter Gemini to Apollo by a survivor who is ejected from the Rising Star (Saga of a Star World).
- According to Encyclopedia Galactica (a non-canonical piece of merchandise published in 1979):
- Described as "intelligent pre-technological beings", they "live in herds, under the absolute leadership of one dominant Boray". Prior to the settlement of Sectar, they were "peaceful farmers living by simple agriculture". The humans' arrival lead the Borays to raid the humans' settlements for supplies, riding "horned stallions" into town by the "light of the full moon", taking "what grain they wanted, killing and kidnapping humans in the process".
- It is also claimed that the landing party from Galactica "negotiated a truce between the two groups, under which the humans voluntarily supplied grain in return for guarantees of peace", noting that the permanence of the solution is unknown.
