Brother Golubus was a Brute stationed on the Covenant ship Valorous Salvation in 2552. He participated in the slaughter of the human population of Beta Gabriel and found a way to make obese humans taste similar to Thorn Beast, which fellow pack mate Ceretus appreciated. His title "Brother" suggests he may have been a prominent religious figure on the ship. Golubus was killed either when the pack turned on one another or when UNSC reinforcements arrived and killed all the Jiralhanae survivors.
