Players can unlock The Splinter Within during the Main Quest, To the Burning Shores, after arriving at Fleet's End.

Note that for majority of the quest, Aloy needs to steer the skiff, a new form of transportation introduced by Seyka.
![]() Map Location |
![]() World Location |
| Objectives | |
|---|---|
| 1 | ![]() Go to the Burial Grounds Head to the north of the town and select the prompt to wait at the campfire for Theoa. |
| 2 | ![]() Go to the Smoke Signal Steer the skiff to head to the island where the smoke signal is, to the south of Fleet's End. Always take note of where you dock the skiff to avoid having to search for its icon on the map. On the other hand, if you decide to complete this quest after completing To the Burning Shores Main Quest, players can use their Sunwing to fly to the island. |
| 3 | ![]() Kill the machines After arriving on the island, a new objective to eliminate the machines will appear. These include leaplashers, ravagers and stalkers. If you cannot find them on the ground, try to find them on top of the overgrown bridges on the island. To defeat the stalker, apply elemental damage to them or target their stealth generator. |
| 4 | ![]() Talk to the Quen Soldier After defeating the machines, talk to the Quen Soldier. He will be on top of a bridge that you can get to by climbing a ladder. |
| 5 | ![]() Search for Survivors and Kill the Machines Use the skiff (or fly with the Sunwing if you completed the To the Burning Shores main quest) to get to the island to the west. After arriving, players need to kill the Waterwings on top of the high platform that Aloy can grapple to. Use a ropecaster to restrict their movement. |
| 6 | ![]() Examine the Corpses and Investigate the Camp After killing the Waterwings, examine the corpses on the same platform. Then use the focus to reveal the three points of investigation. These include the bedrolls, the Frost Glinthawk, and the gathered salvage. |
| 7 | ![]() Search for Tracks and Follow Them Use the focus in the same area to reveal the tracks and follow them. They will lead you to a grassy area with a corpse that needs to be examined. |
| 8 | ![]() Follow the Tracks and Examine the Drag Marks Follow the tracks again but this time they will lead onto the beach. This beach will also have drag marks that Aloy needs to examine. |
| 9 | ![]() • Go to the Site of Enki's Boatwreck • Scan the Debris • Recover the Focus Use the skiff to travel to the site of the Boatwreck. It is recommended to dock the boat at the nearby island the swim the rest of the way. Players will need to scan then interact with the Tideripper's tail to complete the objective. the Tideripper will be swimming in a definite circular path. Cut it off by swiming in a straight line to the tail. Note that this will initially be the objective called Go to the Southwest Island but will change after the objective of Examine the Drag Marks. |
| 10 | ![]() Search the Tower for the Shipping Manifest Use the skiff to travel to the island with the tower. Once there, Aloy needs to glide with the shieldwing to ride the thermal updraft. Make sure to target the climbable bar on the outside of the tower. |
| 11 | ![]() Search the Tower for the Shipping Manifest After climbing, there will be a grappling point on the upper left side and then another thermal updraft to glide through to the next platform. |
| 12 | ![]() Examine the Console After grappling and climbing all the way to the top, there will be a console and an Ancient Valuables Chest nearby. Activate the Holo projector at the console. |
| 13 | ![]() Confront Rokomo and Return to Theoa Head back near Fleet's End to confront Rokomo. He will be on the beach in between some half sunken and dilapidated building frames. Speak with him then return to Theoa, who is nearer to the center of the settlement to end the quest.. |

The machines on both islands will usually be on elevated bridges or platforms. It is important to be mindful of their attacks so that Aloy does not fall off of them and lose their positioning advantage. One way to do this is to get their attention and lure them off of these elevated platforms to fight on the ground.

A lot of the enemies you will need to kill will have shock based attacks so it is best to equip shock resistant outfits.

Like all flying enemies, the Waterwings will try to fly off so it will be more difficult to target their weak spots and predict their attack patterns. Equip and use a Ropecaster to restrict their movement.

During the objective of recovering the focus, the Tideripper will swim around in a definite circular path. Do not try to follow behind it but instead, swim across its circular path and predict when its tail will be right in front of you on the other side.
