After a quick trip to The Interloper, it’s time to explore Ash Twin. In this Outer Wilds guide, we’ll help you find the Ash Twin Towers, the Sun Station, and the Ash Twin Project.
Ash Twin Towers
Much like Ember Twin, the surface of Ash Twin changes over time. The sand will drain off of Ash Twin and fill up Ember Twin over the course of the 22 minute loop.
The equator of the Ash Twin is ringed with towers that correspond to the planets in the system. The first one we’re looking for is the first one that emerges from the sand.
It takes about a full tank of oxygen’s worth of time for the sand to drain away, so it’s useful to stay in orbit for a little bit. Watch out for the Ember Twin as you orbit Ash Twin. Keep moving around, and watch for a gear-shaped tower to start poking out of the sand. That’s our goal.
Just make sure you land your ship a little north or south of the equator so it doesn’t get sucked up with the sand and end up on the other planet.
The first door that emerges on the tower will have a broken lock, so you can’t go in that way. Head to the opposite side of the tower, and wait for an open door to appear. Again though, watch out for the Ember Twin as it orbits. If you get caught in the sand column, you’ll get sucked up onto the other planet.
The room inside is filled with cactuses. It’s very unlikely you’ll make it through without puncturing your suit. You’ll have time to patch it and trees to refill your oxygen tanks in a few seconds. Take the first right, and follow the hallway around to the left.
On the opposite side of the room from where you started, you’ll find an elevator beam leading up. Jump over the cactus to get into the beam, and ride it up.
Stand on the blue glass teleportation pad in the middle of the room. Look up, and wait for the sun to appear. You’ll get warped to the Sun Station.
When you land on the Sun Station, look for a gravity wall leading up. Follow it to the top, and jump to the next gravity wall as well. At then end, read all of the Nomai script, and then use the blue ball lock to blow the door.
Jetpack your way straight through the door. You’re aiming at a tiny door with yellow chevrons near the top of the tower opposite you.
Inside, read the Nomai scroll on your right. There’s a wall leading up in this room, but you don’t have to go up. The wall leads to an overlook with nice views but nothing to find or read.
Instead, head down through the hole in the floor. You’ll end up on another gravity wall that forms a room perpendicular to the room you started the tower in.
Stick to the right wall when the room opens up. Read the Nomai computer there for a little more information.
Next, look for the benches in the middle of the giant window. Pick up the Ash Twin Projection Stone from next to the Nomai skeleton. Take it to the nearby wall, and read all the Nomai script to learn about the Sun Station’s shortcomings.
Part of the script will suggest that the Nomai return to the Ash Twin, so let’s do that. Retrace your steps to the warp pad.
Ash Twin Project
When you return to the Ash Twin Towers, unlock the door. Watch out for the Ember Twin as you continue across the bridge. The next towers you come to are our next stop.
When you reach the towers, turn to the one on the left. Follow the spiral ramp to the right of the door up, and then ride the elevator beam to the top of the tower. Hop across the gap, and pick up the scroll from the shelves there.
Drop back down to the bottom of the elevator beam. Cross the bridge to the other tower. The roof is missing on this one, so drop down through. Cross back to the other tower, and read the Nomai scroll.
Back outside, stand under the bridge between the two towers. Under the bridge, the Ember Twin’s sand column won’t be able to pick you up. Stay here, and wait for the Ember Twin to approach.
When the sand column is right overhead, step onto the warp pad in the broken tower (not the tower where you read the scroll). This will warp you down to the planet’s core and the Ash Twin Project.
Follow the path forward. Read the Nomai computer in front of all of the masks, and then continue on.
Read all of the Nomai script along the wall on your left as you keep following the path, and you’ll learn a lot more about the Nomai’s various projects around the solar system.
After the script wall, there will be a projection stone wall on your right. Pick up and read the Probe Tracking Module, Brittle Hollow, Timber Hearth, and Giant’s Deep Projection Stones. You’ve seen a lot of this information elsewhere, but there are new notes added on these stones.
The final stretch of the Ash Twin Project isn’t useful just yet, but it’s good to learn how it works. There are two blue ball switches here. The big one along the floor opens the containing walls around the project’s warp core. The smaller switch off to the side turns on and off the project’s artificial gravity. That one is useful if, say, you were to want to retrieve that warp core at some point in the future.
Once you’ve read everything, return to the Ash Twin Towers via the warp pad.
Mining Site 2b // Timber Hearth
Back at the towers encircling the Ash Twin, continue the way you were going — away from the Sun Station tower. The next tower you come to has another warp pad inside. Stand on it, look up, and wait for it to warp you to Timber Hearth.
When you land, exit the warp pad’s spiral walls, and follow the path down under the Nomai-built arches. When you reach the broken bridge, carefully jetpack across the broken pieces, and keep heading toward the waterfall.
Walk through the waterfall, and continue following the path down. Unlock the big down to reach Mining Site 2b.
At the bottom of the path, you’ll end up next to a Nomai skeleton. Step forward to the ledge, and look down below you. Drop to the platform, and continue down onto the next two platforms.
Jump into the elevator beam, and ride it to the top.
Read the Nomai scroll in the wall near where you land, and then turn left. Grab the Ash Twin Projection Stone on your way past, and continue to the end of the path.
Drop the projection stone into the wall at the end, and read all the Nomai script.
What have we learned? // What’s next?
We’ve learned a lot on this trip. We practiced using the Ash Twin Towers to planet hop, and we visited the failed Sun Station. We also made it to the Ash Twin Project, which is the cause of the 22-minute time loop.
We’ve found the Nomai’s warp core, and we should go see where it was made in the Black Hole Forge on Brittle Hollow.
