Siege of the Warmind
The Guardian enters the canyon leading to the Forgotten Shore.
The Guardian reaches the Forgotten Shore and heads toward the old communications where one of Rasputin's relays are located. The Guardian descends the stairs inside, and when entering Bunker RAS-2, sad orchestral music begins to echo throughout the room.
The large triangle doors are lifted open, and the Guardian enters Rasputin's bunker.
The Guardian continues deeper into Rasputin's bunker before stepping out into the Seraphim Vault, finding a Hive force to the left.
The Guardian fights through Knights, Acolytes, and many Thrall. Once reaching the end of the corridor, the Guardian finds two doors leading into the control room. The doors are open, and the Guardian enters the control room, with Rasputin in the middle of it. When doing so, the doors are sealed shut.
The Guardian approaches the control panel on the far side of the room. Everything seems normal for a while, but then all screens turn red with a loud noise. Old Russian symphony music begins to play in quick tones over the speakers.
Omnigul appears above the control panels, summoning a horde of Thrall in front of her.
After the Guardian defeats the Thrall, Omnigul flees, and teleports into the room outside of the main chamber, visible through a window. Omnigul then starts to summon more Hive forces. The Guardian battles and kills these forces, and finally, Omnigul summons a powerful Ogre, the Might of Crota. After a long battle, the Guardian defeats the Might of Crota, and the room brightens up and the music fades out. Machines begin to turn on and whir back to life.
