Optus Siluu, Coalition Ally

Optus Siluu, Coalition Ally is a Cabal Psion and a Optus of the Imperial Cabal. They are one the three members of Caiatl's boarding party that can be called to Royal Pools of the Derelict Leviathan.

Gameplay
Siluu wears the same armor that is typical of other Imperial Opti: bulky, dark-grey armor with gold markings and Caiatl's sigil emblazoned on their chest piece, and black capes with a large, white symbol on it, with blue areas near the end. They come equipped with the rifle variant of the Cabal Slug Launcher.

A beacon of the Imperial Cabal can occasionally appear in the Royal Pools of the Derelict Leviathan, on the far left corner of the area from the where you enter. Upon being activated, a boarding party will be summoned, consisting of two of the following three potential coalition allies: Bracus Gaa'ron, Bracus Han'uk, and Optus Siluu. Seconds after they arrive, several hordes of Scorn will begin to spawn nearby. You will then have to fight your way through the enemies until you reach the other side of the area. After you have killed enough Scorn, they will call upon their champions, Au'gor, Devoted of Calus, and Jai'ek, Supplicant of Calus, to assist in repelling you and your Imperial Allies. If you are successful in eliminating both of the bosses in time, you can claim loot from the chest that spawns, and you will be awarded the 'At the Behest of the Empress' Triumph. The boarding party will leave the area not long after the event has concluded.
