Horizon Forbidden Westis full of Relic Ruins, andBurning Shoresis no different. Murmuring Hollow can be a bit of a head-scratcher, but it’s well worth exploring to completion; not only does it provide you with anew Ornament for Stemmur, but it also leads right into theA Stranger In The Darkside quest.

In order to solve this Relic Ruin, you’ll simply need your wits — andaccess to your Sunwing. If the campaign has locked you off from using it, simply continue with the next campaign mission first. Once you have gained access to your Sunwing again, you’re ready to begin Murmuring Hollow.

How To Reach Murmuring Hollow

To accessRelic Ruins: Murmuring Hollow, you’ll want to head directlysoutheast of Fleet’s End. If you hit the Thunderjaw Site, you’re on the right track. Continue southeast until you reach a crumbled building with a chunk crumbled out of the side and anOseram camp set up just outside. From here, look for the gaping hole leading underground.

Down here, you’ll find a sealed door that required a Key Module; this door will lead into theA Stranger In The Darkside quest, so ignore it for now.

Across from this sealed door, you’ll need to reach a sealed door requiring akey code, but the path is blocked by two decrepit tram cars.

How To Get The Door Key Code

Just past the Key Module door, you’ll find a datapoint that hints at the required key code can befound on an upper floor.

Ride your Sunwing to the rooftop. Up here, you’ll see a datapoint inside the building, but you’ll be unable to scan it from outside. Instead, turn your attention to a sealed grate on the rooftop. Your Pullcaster won’t work. Instead, mount your Sunwing. When you’re near the grate, you’ll have a prompt to “Grab Metal Clamp” with triangle. Your mount will rip the grate off, clearing you a path inside.

Once inside, search for an elevator shaft; use this to climb to the floor above, gaining you access to the datapoint, which includes the requiredkey code: 1315.

With the passcode in your possession, now you’ll just need to figure out how to move the trams below.

How To Move the Trams

Return below ground, and use your Focus to scan around the environment. You’ll eventually find anenergy cell. You need this, but the path down here is completely sealed off due to the broken-down trams. Instead, return aboveground where you found thatOseram campjust above the entrance to Murmuring Hollow. Behind the camp, you’ll find a rappel point; go ahead andrappel downto the landing below. This gains you access to the other side of the tram station.

You’ll hear a stranger call out for help; Aloy will find the voice familiar. This will lead into the A Stranger In The Dark side quest.

Plug in the passcode you discovered earlier (1315). This will open the door, granting you access to the next room. In here, pick up “Kyle’s Last Ball,” adding it to yourOrnament Collectionand completing Relic Ruin: Murmuring Hollow.

Before leaving, you’ll notice another locked door and a slot for an energy cell. Return to the second tram, remove theenergy cell, and slot it in this new spot. The door will unlock, and you’ll pick up theAuxiliary Key Modulein the next room. This will grant you access to that first sealed door across the room, and it will then begin you on theA Stranger In The Dark side quest, where you’ll encounter a familiar face (familiar to veterans of the Frozen Wilds DLC fromHorizon Zero Dawn, that is).
