Hall of Guardians, The Last City, Earth
Zavala: Guardian, the City has need of you. I have need of you. A mercenary company, the Sunbreakers, have been spotted on Venus. I need you to speak on my behalf.
The Guardian heads to Venus.
Zavala: What does it mean to be a Titan? As a Titan, you are a part of the City - in a way no Warlock or Hunter could understand. The dream of the City rests upon our shoulders. Then there are those that find a path outside of our Walls. Those that take up with leaders they barely understand. So it has ever been with the Sunbreakers. The Hammer of Sol is a flame in the darkness. But fire burns without thought. It is time that fire came home… To keep the City and her Walls warm throughout the long night.
Ishtar Commons, Ishtar Sink, Venus
Zavala: A legion of Sunbreakers were spotted near a Vex Gate in the Ishtar Sink. They do not stay in one place for long.
The Guardian heads towards the Sunbreakers' location.
N/Gen Branch, Ishtar Sink, Venus
Ghost: I'm detecting what looks like a Sunbreaker's beacon, but it's interlaced with Vex feedback.
The Guardian searches for the Sunbreaker's beacon, defeating the Vex which they encounter. The Guardian finds the beacon. Ghost accesses the beacon and plays a transmission from it.
Ouros: Fall back, fall back! Should've known Osiris [garbled]. Protect the forge once they're in! You remember [garbled].
Zavala: Osiris? Find out where they've gone, Guardian. My report said they were heading for a Vex Gate.
Dig Site 4, Ishtar Sink, Venus
The Guardian searches for the Sunbreakers. The Guardian finds a Vex gate. An Ultra Hydra appears. The Guardian defeats the Ultra Hydra.
Ghost: The gate's offline. If I can map that conflux, I might be able to figure out where it leads.
Ghost scans the Vex conflux. The Guardian finds several dead Sunbreakers.
Ghost: Zavala, the Sunbreakers opened this gate to Mercury. I have the coordinates.
Zavala: Then plot a course. Find their forge, Guardian. If the City hopes to weather the oncoming Darkness, we will need the flame it holds.
