The Guardian approaches the Dreadnaught.
Eris Morn: Guardian, we are poised to strike, and strike first. Meet me aboard the Dreadnaught. I will perform our ritual where I fell. Oryx will bend to our strength, and my throne will be his prison.
HALL OF SOULS, DREADNAUGHT, RINGS OF SATURN
The Guardian regroups with Eris at the binding ritual location.
Eris Morn: Guardian! Savathûn and Xivu Arath’s forces close on us like jagged teeth. Thwart them. Protect the ritual as I bind the Echo of the Navigator to my throne world. I will subdue the Taken King. Capture him. Cleave him from his throne! He will not escape my power. I will be his jailer yet!
The Guardian sacrifices the flesh of Akka to summon forth the Echo of Navigation and begin the Ritual of Binding.
The Guardian buys time for Eris to complete the Ritual of Binding.
Eris Morn: His power is immense. But so is yours, Guardian!
The Guardian completes the second binding.
Eris Morn: Our bindings hold fast! Press on!
The Guardian completes the Ritual of Binding.
Eris Morn: [cackles menacingly] Magnificent.
