Destiny 2 Pale Heart Guide: Complete Guide to Finding & Destroying All Paracausal Geometries for The First Knife Ship

Unlock the Exotic ship The First Knife by mastering Paracausal Geometry locations in the Pale Heart with this ultimate 2026 guide for Guardians.

Okay, fellow Guardians, I just spent what felt like a lifetime hunting down those elusive Paracausal Geometries in the Pale Heart, and let me tell you, it was a JOURNEY. 😅 But I finally got my hands on that sleek, gorgeous Exotic ship, The First Knife, and it was SO worth it. If you're stuck on this Final Shape triumph like I was, I'm here to break it all down for you, step-by-step. No more wandering aimlessly! This is your ultimate 2026 guide.

First things first, let's get the basics straight. You can't just stumble upon these glowing red and blue cubes. The whole process starts with the 'Alone in the Dark' questline. And here's the kicker—you gotta run it 11 times. Yep, it's repeatable, and each completion unlocks a new 'Paranormal Activity' event on your Pale Heart map. This is your breadcrumb trail to every single cube pair.

Once you've tracked an event, follow your marker until you find a small, glowing orb in a circle on the ground. Commune with it to get the 'Aura of Balance' buff. This is your key! Without it, you can't damage the cubes. The mechanic is simple but needs precision:

  • 🔴 Red Cube = Destroy with Darkness damage (Strand or Stasis).

  • 🔵 Blue Cube = Destroy with Light damage (Solar, Void, or Arc).

The trick? You have to stand where you can see BOTH cubes at once. Shoot one, and a circle spawns at your feet. You MUST stay inside it while you destroy the second cube. Timing and positioning are everything!

Now, let's dive into the locations. I'll list them in the general order you'll find them. Remember to track each Paranormal Activity on your map after each 'Alone in the Dark' completion!

1. The Transgression

This is your first test. The commune point is on top of a small structure in a deep room.

  • Stand by the red cube between some pillars (Darkness).

  • The blue cube is underneath that same structure.

Line them up and claim your first geometry!

2. The Blooming (Southwest)

Head to the large rock pillar. The commune point is on a sneaky little ledge nearby.

  • Get the buff, go past it, turn left. The blue cube is right in front of you.

  • Look across the valley—the red cube is hiding behind a big rock.

A bit of a scenic shot! 🌄

3. The Impasse

From the landing zone, look for the big pyramid. The commune point is on a raised spot next to it.

  • Head to the second large structure on the pyramid's left (you might remember it from Visions of the Traveler).

  • Stand on the wall near the massive drop. You'll see the blue cube under the entrance to The Transgression.

  • The red cube is hanging above where the commune point was.

This one requires some parkour vision!

4. The Lost City

Go towards Micah-10, then drop down right. The commune point is outside a doorway.

  • Find the statue ahead of the point and climb it.

  • From the top, spot the blue cube on the roof of the building you came from.

  • The red cube is to the right, below a large building.

5. Lost City Outskirts

Head back toward the start of the Final Shape campaign. Find a courtyard with a big tree—commune point is there.

  • Stay in the courtyard, face the tree, go up the stairs to the left.

  • Peek through a gated opening to see the blue cube.

  • The red cube is on the other side of the same tree.

Easy two-for-one from one spot!

6. The Seclusion

Venture deep into the caverns with upside-down trees and waterfalls. The commune point is at the entrance.

  • The blue cube is visible right inside the room.

  • The red cube is trickier, hiding under a rock pillar on the side.

Jump to the platform under the blue cube, then to one next to the pillar for the perfect vantage point.

7. The Landing

At the landing zone, find the tall blue building near a waterfall. The commune point is behind it near a huge tree root.

  • Climb onto the root and stop halfway.

  • The blue cube is near a bronze statue by the blue building.

  • The red cube is under the waterfall itself. You might need a little jump for a clear shot!

8. The Forgotten Deep (Lost Sector in The Landing)

This one's a mini-dungeon crawl. Fight through Hive to break crystals and progress.

  • The commune point is in the third room, near a large statue.

  • Find a small platform near the room's exit and climb a vent.

  • The red cube is under a building on your right.

  • The blue cube is across the room above a trellis.

Patience is key here!

9. The Blooming Deep (Lost Sector in The Blooming)

Another Lost Sector! Go until you find a pool of Transcendence. You'll pass the blue cube on the way.

  • The commune point is just ahead. Activate it, then backtrack to the Transcendence pool.

  • Stand on the little ledge in the middle. From here, you can see both the blue and red cubes simultaneously. Probably the easiest pair!

10. The Divide

The commune point is under an arch. But the cubes are a hike away!

  • Look for another archway next to the cave entrance to this area. Go up until you see a broken, crashed plane.

  • Stand on the plane's nose. Turn around to see the red cube inside the cockpit.

  • Look down from the nose tip to spot the blue cube (which was near the commune point).

Very cool vantage point. ✈️

11. The Refraction

Last one! The commune point is west of where Ikora's ship crashed.

  • Get the buff, then climb the large tree branches to reach a rocky outcrop above the ship.

  • From the rock, look ahead and slightly left for the red cube.

  • Look down toward the river to find the blue cube (it might be hiding behind leaves, so move around).

And... DONE! 🎉 After that 11th geometry shatters, the triumph pops, and The First Knife is yours. It's a stunning ship, a real badge of honor for mastering the Pale Heart's secrets.

My Pro-Tips for a Smooth Hunt:

  • 🗺️ Always track the Paranormal Activity on your map. Don't rely on memory.

  • Be patient with positioning. The circle mechanic is strict.

  • 🔫 Have a Darkness and Light weapon ready (or know your subclass abilities) for quick swaps.

  • 🧭 Use the in-game markers. The Pale Heart can be a maze.

  • 👥 Squad up! Having friends spot cubes from different angles is a huge help.

It's a grind, but honestly, exploring every nook of the Pale Heart was half the fun. The environmental storytelling is chef's kiss. Good luck, Guardians! Go get that knife. 🔪✨
