Step into the Vex Portal to draw closer to the Traveler.
Find a way out of Ghaul's command ship.
- When you arrive at the top of the building, you will find Zavala, Cayde-6 and Ikora Rey winded, and wounded waiting for you.
- When you are ready, step on through the portal in front of you that Cayde-6.
- This will bring you onto Ghaul's ship.
- Once on the ship, head forward and down the slope in front of you.
- Go forward through the open doorway and the next door beyond it.
- Approach this door carefully.
- On the other side of the door is over a dozen War Beasts that are asleep.
- If you are going to fight them, get past them to the far side of the room.
- This gives you a better point to funnel them toward the Guardian.
- After that, go through the door on the other side and up the small ramp.
- Go on up the pipes and through to the next portion.
- Go over to the right, dropping off the pipes from there.
- Go down and then up the far side ramp to reach Quarterdeck.
- This will bring you to another chamber with a number of Cabal inside it.
- You will encounter Psions, Phalanx, and Final Guard Straff.
- Just beyond Final Guard Straff is an elevator you can take upwards. Do so.
- THis will bring you t the top of the ship.
- Go forward to the swirling vortex or flame and darkness to trigger the battle with Dominus Ghaul.
