What Are Relic Ruins and Ornaments

Relic Ruins in Horizon Forbidden West are optional activities that take you to what’s left of Old World buildings. You must solve puzzles to reach a specific spot in order to obtain an Ornament, one of the game’s collectible items.

There’s a total of ten Ornaments, each Ornament represents a holiday. They can be given to Stemmur in Hidden Ember. He will then project holographic lights on the sky depending on which Ornament you give him.

An Errand Mission called Nights of Lights must be done before turning in all your Ornaments. It is very similar to every Relic Ruin but the puzzle is easy and quick to do.

Nights of Lights Mission Walkthrough

Nights of Lights is an Errand that is located in Hidden Ember. It is unlocked after completing the main quest Sea of Sands. You must talk to Stemmur to get this mission. He’ll ask you to recover a “Gizmo” that’s on the ruins. In reality, this is an Ornament like the ones you retrieve from the Relic Ruins.

Venture into the ruins, the game will lead you to this building that’s full of blinding lights. This is one of the few ornament-related missions that do not require the Igniter or Vine Cutter so don’t worry about that.

You’ll see a sealed door with a terminal next to it as soon as you enter. To open it you must find the password.

Turn to the left, you will see a climbing node. Use the Pullcaster to get up and then continue to the upper floor.

There’s a Datapoint, climb on top of the metal boxes and scan it. You’ll notice that it mentions the number 135, these are the last three digits of the code. Continue to the right side.

There are two stacked crates but you can only move one. The one on top must be moved to the right.

Go to the right side of the room where you’ll see a metal cage. Get on top of it and pull the top crate.

Now remove the bottom crate. Look for the ramp that’s just a few meters away.

Move the crate through the platform and leave it in the location that’s shown in the picture below. Both crates must be stacked again, time to get the second one.

Use the Pullcaster to move the first crate back to its original location.

Place it right in front of the crate that’s on top of the platform. Now simply push the top crate, both crates should be stacked after this. Push them in front of the metal cage that’s right in front of the ramp.

There’s a small opening on the right side of said metal cage. It’s hard to distinguish due to the poor lighting of the place but there’s a crate at the back. Pull it through the opening.

Now jump on top of the crates to get to the top of the cage. The crate that you just moved was blocking the entrance but now it’s possible to get inside.

Just climb down and crouch to get in. There’s a vent on the floor, you can’t miss it. Open it with the Pullcaster and move forward.

The vent leads to the roof of the building. Walk until you see a metal clamp. Pull the metal clamp to gain access to the last area.

Aloy uses the rope to pull the metal clamp and break the wall

Scan the Datapoint, it has the first three digits of the code, 7 3 9.

Type the code in the console starting with the three digits you just found. The complete code is 739135.

The last Ornament or “Gizmo” as Stemmur calls it will be behind the door.

You will be rewarded with Ancestor’s Return, a Legendary Shredder Gauntlet. The tenth Ornament is found in the DLC, The Burning Shores. You do not need it to complete this Errand and get the weapon.
