Nights of Lights is an Errand given to you by Stemmur in Hidden Ember. In this walkthrough guide, we'll detail the exact code needed to open the Nights of Lights Relic Ruin door code, as well as guide you through who to talk to, what to do, and any tips or tricks to help you defeat machines that come your way. This Errand ties directly to the Relic Ruins and the Ornaments you find at those locations.

Stemmur, the Wordsmith in Hidden Ember, needs Aloy's help collecting an Old World gizmo located in the ruins in the underground dome.

Nights of Lights Guide

This Errand is connected to the Relic Ruin Ornaments. See our Relic Ruin Ornaments guide for more information on how to get the rest of the ornaments.

Aloy travels back to Hidden Ember and speaks to Stemmur, part of the trio who are revitalizing the settlement. Stemmur mentions that there is a gizmo in the Old World ruins below and he needs help in getting it. Aloy offers to lend a hand.

Go to the Underground Ruin

Go to the underground ruin by going all the way down the shaft. Head to the door with the green light that is located to the left. Rappel down and go out of the door. Head right towards the Eiffel Tower. There will be some Burrowers and a Snapmaw to deal with, but you can sneak past them if you choose.

Search the Ruin for the Gizmo

Approach the ruin and enter the door on the left. There will be a door on the far end that needs a code. This is the room that you need to get into. In the room, you can see that there is a Relic, the gizmo that Stemmur wants. To the left is a small hallway with a grapple point. Grab it with your Pullcaster to get to the next floor. Go up the stairs and there will be a series of caged storage. Scan the datapoint. Read through the information to get the second half of a six-digit code ( to the locked door below.

Go through that cage to the other side. Go left and check the other caged storage. Aloy will see a hatch in the floor in the one to the far right. The cage itself is too tall for Aloy to jump up into, so she will need some help.

Get the Two Crates and Find the Nights of Lights Door Code

To the cage to the right, you will see two crates, but if you pull them, they will get stuck on the low door. You will need to move the top crate off of the bottom crate so that you can pull the bottom crate out. Go to the small cage in the corner to the right. From here you can use your Pullcaster to pull the top crate off the bottom crate.

Go back to the middle cage and use your Pullcaster to pull the bottom crate out. Now you have to get the top crate out as well, but now it's sitting on a shelf. Take the crate you have and put it on the left side of the cage. Jump on the cage and now use your Pullcaster to target the top crate. Pull the crate and it will land on the floor.

Now that you have both crates, you will need to stack them again in order to jump the high cage. In the left corner across from the tall cage is a ramp. Push one of the crates up the ramp and set it on the platform. Take the other crate and push it just below the other crate, against the platform. Now go up the ramp and push the crate on top of the bottom crate.

Push the stacked crates to the tall cage. Before you jump in, go to the right of the cage and look through the hole in the cage. You will see that there is a crate blocking the hole in the cage's ceiling. Use your Pullcaster and pull the crate away from that opening. You should not be able to jump into the tall cage, go through the hole in the ceiling and reach the hatch.

Open the hatch with your Pullcaster and jump in. Follow it to a vent opening. Kick open the vent and you will be outside. Go right and you will see a metal clamp. Use the Pullcaster to pull the rubble to reveal an entrance to an old office. Go in and scan the datapoint to get the first part of the six-digit code (,

Unlock the Door and Take the Gizmo Back to Stemmur

Go back to the secured door and enter the code 739135. The door will open and you will be able to collect the gizmo. Return to Stemmur and hand it to him. He will active the gizmo and before you will be a brilliant light display of the Christmas holiday. If you have additional ornaments, you can have Stemmur display them.
