From Destinypedia, the Destiny wiki
Seen exclusive to Imperial Cabal members, Optus' (Opti) are Psions with the citizenship of Freeborn that have been given the added benefit of a military ranking. Although how high or low the rank of Optus is currently remains unknown, Optus' are above their rank-and-file compatriots and may be very similar to a Bracus. Many Opti take the form of named Commanders, although there also exists an unnamed Optus Psion variant.
They later make another appearance in Season of the Risen, assisting Guardians of The Last City against the Lucent Brood by sending the Guardians into the mindscape of Hive Lightbearers in order to weaken them and detain them for psychic analysis.
Optus Psions are identical to other Psions apart from possessing far greater durability.
