The Eye oversees all.
It's the watcher of our faithful little prison, a prison of the lowly and the opposers of the Frontier's grand plan. It knows what's best for not just Fallen, but Cabal and even humanity as we know it. Rarran Prime faithfully serves as the warden...
..The warden, of the Prison of Kings...

(The Guardians appears in the Prison Complex of the Prison of Kings, with Prison of Elders cells surrounding the large room. Using some sort of telekinetic beam, Rarran Prime, the giant Servitor in the background, lifts a cell and places it an arena, speaking in mechanicalized Eliksni language.)
Beriks: Our Servitor demands the destruction of a lesser eye...Mecher Orbikis 6...(Hiss)...The eye was influenced by Vex, long ago, when the Wolves cried for rebellion. The eye only sees destruction of our race...Kill it dead, lightwielder. Dead.....
(The Guardians makes their way through a long hallway into a door on the right: From there, Fallen wearing spiked, black armor are seen patrolling. The Fireteam makes quick work of them, before moving on deeper into the Prison.)
Ghost: It amazing, how devout Fallen get about their Servitors...
Syrianna: Don't be too surprised. I've taken one of their bodies before for experimenting; they have mind cores in their helmets. Keeps them mindless and under the Servitor's control. (Whispering) Damn, why did I not think of that?...
Cyrus: Because I wouldn't have let you do that. I caught this thing a long time ago, had to keep it down there for so long...It was actually the first member of, and the reason we founded, the Prison of Kings.
(The Guardians fights through more Fallen, occasionally encountering Scorch Captains with a "Disciple of Mecher" title. As they keeping moving through the dungeons, Rarran Prime keeps speaking a mechanilized voice. Finally...)
Beriks: The lesser eye is within that arena....
(A different mechanilized Eliksni voice is heard, but garbled, assumed to Mecher Orbikis 6.)
Beriks: It says: The inevitable cannot be stopped. All will be burned away, until there is nothing but beautiful, black ash...And I, will lead those flames to victory...
Cyrus: Preachy, but that's not gonna happen. Guardian, I wish you luck: Chances are, that thing won't like visitors.
(The door opens to the arena, revealing a large, circular room with ledges on the walls, where Fallen snipers will reside. Looking up, a large white light brightens the room. Firstly, Vektis walks in from a door in the arena, before attacking the Fireteam. Details about Vektis' strategies later, but once done, Vektis' body will fall on the ground and be burnt into ashes.)
(The lights are broken. M.06's voice is heard as he descends onto the battlefield, with it's red, modified eye only being visible. So far, it fights almost identical to Sepiks Prime, just with a few more teleports thrown in. At 80%, lights dimly reveal M.06's full body, and his real strategies are revealed. Rapid laser blasts, a powerful Void cannon, and his Atheon-like ability to send Guardians into "the inevitable". In the inevitable, 3 Guardians are being chased by a supernova in a destroyed Tower. Meanwhile, the 3 not in "the inevitable" have to murder 3 Dregs hidden around the map to bring the Guardians back, or the entire team will wipe. Rinse and repeat until 30%, where his tactics become more like Sepiks Prime's again, except with the time travel and lasers in his routine attack. Also, the room will flood with Vandals and Captains, making the boss fight harder. Continue until death, where MO6 is sent into a paralyzed and broken state midair, like a Cyclops. Rarran Prime is revealed, when a wall is removed from the arena, and he destroys MO6 for good with a giant Arc blast of energy.)
Syrianna:...Too bad. I wanted that Servitor...
Cyrus: And, that was a win for the Frontier, and even if they don't know it yet, the City. That inevitable could've actually happened, and it had the capabilities to do just that..But you put an end to it. Big day, big rewards, Guardian.
