The Rupture, Io

Zavala: Not long ago, we detected a massive burst of Vex activity on Io. Inside the Pyramidion. We need eyes in that structure, Guardian. Get moving.

The Guardian heads towards the Pyramidion.

The Endless Gate, Io

The Guardian continues towards the Pyramidion, defeating the Vex which they encounter. Shuttered Mind, a Vex Hydra, appears. The Guardian defeats the Shuttered Mind. The Guardian goes through a Vex portal and finds the Vex fighting against the Taken.

Ghost: We've discovered the cause of the Vex high alert. There's a Taken incursion in progress inside the Pyramidion.

Zavala: Taken. Any sense of their objective?

Ghost: Unclear for the moment. Stand by.

The Guardian searches for the source of the Taken incursion, defeating the Vex and the Taken which they encounter. The Guardian finds a giant Vex sphere, with a Vex barrier blocking the door into the sphere.

Ghost: There's a giant Vex sphere in this chamber. Like the ones on Nessus, but colossal. And there's a door leading inside. That could very well be the Taken's objective.

Zavala: Their first major offensive since the Dreaming City. Get inside that sphere. We need to know what they're after.

The Guardian fights against the Vex and destroy four Vex Lenses, disabling the Vex barrier to the door inside the Vex sphere. The Guardian enters the Vex sphere.

Ghost: Every square inch of interior surface area in this sphere is coursing with energy. Let me see what I can find out. Scanning…

The Guardian searches for the source of the Taken incursion, defeating the Taken and the Vex which they encounter.

Ghost: Zavala. This whole sphere is a dedicated processing structure. A giant Vex computational array.

Zavala: What could the Taken want with a Vex computer?

Eris Morn: The Taken want nothing.

Zavala: Eris. Eavesdropping, I see.

Eris Morn: Don't bother guessing the Taken's intentions. Ask instead what is sought by the hand that directs them.

The Guardian heads further into the Vex sphere, defeating the Taken and the Vex which they encounter. The Guardian finds a door blocked by a Vex barrier and four Vex Lenses. The Guardian destroys two Vex Lenses. Juraag, the Waylaid, a Taken Phalanx, appears. The Guardian defeats Juraag, the Waylaid and destroys two more Vex Lenses, disabling the Vex barrier. The Guardian goes through the door and heads further into the Vex sphere.

Ghost: This Blight… does it look familiar to you. Like the Blight in the Dreaming City?

Eris Morn: Savathûn extends her reach at last.

Zavala: Savathûn? What makes you so certain?

Eris Morn: There's no certainty where the Witch Queen is concerned. But I have strong suspicions. Above all, she seeks knowledge to inform her plans and seeks pawns to carry them out. The sphere offers both.

The Guardian finds an area with a door blocked by a Vex barrier and four Vex Lenses. More Taken appear. The Guardian defeats the Taken and destroys the Vex Lenses, disabling the Vex Barrier. The Guardian goes through the door and heads further into the sphere.

Ghost: Taken influence is thicker down here. They're not trying to break in - they're infesting from the inside out. There must be some anchoring Blight nearby. If we're really unlucky… a portal to an Ascendant Realm.

The Guardian finds a circular area with a Taken Blight in the centre.

Ghost: There. That must be the anchor - the Taken's route into the sphere. Destroy it!

The Guardian destroys the Taken Blight. Baurisk, Envoy of Savathûn appears. The Guardian defeats Baurisk, Envoy of Savathûn.

Ghost: We killed the Taken commander and secured the central sphere. I think the Vex can handle the rest.

Eris Morn: Savathûn is gathering her strength, Zavala. If we hope to survive what's to come, we must prepare.

Zavala: We defeated Oryx. If Savathûn wants a fight, she'll get one.

Eris Morn: She is not as foolhardy as her brother. She would never risk a direct confrontation. We will know her next move only when she makes it - and only if we're wise enough to recognize it.
