If you’re stuck trying to start the Saturnism mission in Destiny 2: Edge of Fate, this guide has your back. Like many players, I ran around Augur’s Bethel for way too long before realizing there’s a hidden puzzle route that unlocks the Central Refinery. Once you’re in, you’ll gain access to the Saturnism mission, and trust me, it’s one of the most unique and satisfying missions in the campaign. I’ll walk you through how to reach the Central Refinery step-by-step, and then I’ll give you a quick preview of what to expect once you’re inside Saturnism.
How to Reach Central Refinery | Saturnism Mission
To start Saturnism, you first need to access the Central Refinery in Augur’s Bethel, located on the eastern side of the Kepler zone. Here’s exactly how to get there:
- Find the Hidden Tunnel: Look for a Matterspark pylon sitting out in the open. Right next to it is a small tunnel sunk into a dip in the terrain. Head inside, and you’ll find a Relocator cannon.
- Step on the Activation Plate: There’s a nearby pressure plate in the tunnel. Activate it to open a previously sealed room.
- Fight the Fallen Captains: In that new chamber, you’ll get ambushed by Fallen Captains. Take them out and grab the explosive charges they drop.
- Destroy Three Ether Canisters: Look around the room for three large Ether tanks. Use the charges to blow them up. No puzzle-solving here, just plant and boom.
- Defeat the Miniboss: A Fallen miniboss will spawn after the canisters go down. Defeat them to unlock the lower floor.
- Enter the Refinery to Unlock Saturnism: Once the door opens, head through, and just like that, Saturnism will be unlocked and ready to play on your map.
What to Expect in Saturnism
Once you’re inside Saturnism, be ready for a mix of platforming, puzzles, and some really cool RSaturnism mixes platforming, puzzle-solving, and some seriously fun Relocator upgrades. Here’s a quick summary of what’s ahead:
- You’ll solve an early pipe puzzle using a Relocator cannon, think of it as the warm-up lap.
- Halfway in, you get access to Relocator II, which lets your shots bounce off satellites and chain together through the air.
- You’ll learn to rotate satellite nodes by shooting them, unlocking new beam routes and teleporters.
- Expect multiple puzzles with chained beams, spinning nodes, and “finally!” moments.
- Toward the end, you’ll need to destroy three machines using gear collected from minibosses.
- It all wraps up with a solid final fight to complete the mission.
Saturnism is one of the more puzzle-heavy missions in the campaign, and it introduces mechanics that you’ll keep using later on, so it’s worth mastering.

Wrap-Up: What You Unlock After Saturnism
Getting into the Central Refinery can be a bit of a headache if you don’t know where to look. But once you’re in, Saturnism becomes a standout mission with smart design and permanent rewards like the Relocator II. It’s worth taking your time to explore and get the mechanics down since you’ll use them again in other missions.
I hope this guide helped you figure out how to unlock the mission or at least saved you from wandering Augur’s Bethel for 30 minutes like I did.
