History of Lonely Travels

Overview

Lonely Travels is a Triumph worth 25 points. It requires completing every encounter of the Sundered Doctrine dungeon solo, without leaving the activity at any point. Sundered Doctrine was added with Episode: Heresy and is set in the Sunken Pyramid in the Savathûn Court.

A Bungie support reply from March 2025 states that the run must also be flawless. The in-game description does not mention deaths, so check the requirement on your own run.

How to complete

1. Reach the dungeon. Sundered Doctrine requires The Drowning Labyrinth. The run starts in Flooded Inspection near The Hidden's base.
2. Solo the six encounters in order.

• Solve the Riddle: direct light beams to matching symbols on the wheels.
• Navigate the Maze: three Resonance crystals unlock a secret chest, followed by rolling boulders. Collect the worm larvae along the way.
• Open the Locks (Altered Convolution): align symbols on two wheels, using Resonance Splinters from Preceptors.
• Zoetic Lockset: four Shrieker enemies share one health pool. The wheel symbols control enemy spawns. Setting the three rightmost wheels to Stop and the leftmost to Kill gives the longest damage phase, and Hive symbols should be avoided.
• Locate the Vault: solve the light puzzle and follow the path through the worm carcasses.
• Kerrev, The Erased: a truth-and-lie puzzle lowers the shield of the mobile Scion boss. Use cover and high-damage weapons such as Thunderlord or Linear Fusion Rifles.

Do not leave the instance. Bungie's reply says disconnects or network issues of any kind would likely count as leaving and invalidate the run. If you are disconnected, start a new run.
