Follow Sylens's trail and confront HADES in Horizon Forbidden West. This guide details how to reach the coordinates, craft the Igniter, and bypass obstacles.

Walkthrough
  1. 1
    From the nearby Campfire, travel southwest to follow Sylens's beckoning. Use the Shieldwing to glide down from the cliff to the southwest.
  2. 2
    You will land near an Oseram salvager camp, where you can start [Salvage Contractor: Barren Light]. There is another Campfire nearby.
  3. 3
    Continue southwest, encountering Rebel Warriors attacking Oseram led by Jelda. Assisting them may reveal the Relic Ruins: No Man’s Land, though it's inaccessible due to red crystals.
  4. 4
    Proceed southwest, avoiding or defeating machines like [Scrappers] and [Leapslashers], until you reach the edge of a lake with a dormant Horus machine.
  5. 5
    Swim across the lake to the southwest, reaching the quest marker under the Horus machine.
  6. 6
    Use the nearby Campfire. Under a shelter to the north, find the New Home audio datapoint. On a table to the southwest, find the Interrogation Log text datapoint.
  7. 7
    Interact with a console on the northeastern end of Sylens’s camp to view a hologram from Sylens.
  8. 8
    Follow the rut left by HADES’ processor core prison along the coast. You may encounter [Frost Glinthawks], [Scrappers], and [Chargers].
  9. 9
    You will reach another [Campfire] with a Hunter selling goods. Continue following the rut trail.
  10. 10
    You may see [Leapslashers] off to the left; ignore them for now. Continue into some ruins and follow the linear path to find HADES’s processing orb.
  11. 11
    Interact with HADES and exhaust its dialog options.
  12. 12
    After conversing with HADES, you will have a holographic chat with Sylens.
  13. 13
    Head forward to a biometrically-sealed door and use Aloy’s genetics to open it.

How to Craft the Igniter:

  1. To bypass the Firegleam-encrusted door, you need to craft an Igniter. This requires a Leapslasher’s Spark Coil and Deepwater Kindle Weed Oil.
  2. Where to find a Leapslasher’s Spark Coil: Southeast of the ruins entrance, find a Leapslasher Site with three Leapslashers. Shoot off a Leapslasher’s Power Cell from their back, above their tail. If you fail, retreat and try again, or find another site.
  3. Where to find Deepwater Kindle Weed Oil: Dive into the water southeast of the Leapslasher Site and search the seafloor for green and red plants.
  4. Crafting the Igniter: Return to the ancient tunnel and use the Workbench near the entrance to craft the Igniter.
  5. Use the Igniter to detonate the Firegleam on the door.
Tips
  • Use the Shieldwing for easier traversal when gliding down from heights.
  • Hide in the grass at the Leapslasher Site to get a better shot at their Power Cells.
  • If you fail to detach a Leapslasher’s Power Cell, retreat and hide until they calm down before trying again.
