The Enlightenment Mystery in Hell Is Us is one of the trickiest puzzles in the Acasa Marshes. It revolves around unlocking a hidden door beneath Jova Village by activating symbols scattered across the marshes. This guide walks you through every step—where to begin, how to find each symbol, and the powerful rewards waiting behind the sealed door.

How to Start the Enlightenment Mystery
You’ll first encounter the puzzle in Jova Village, where a well in the town square leads down to the sewers. At the bottom, you’ll find a large locked wooden door marked with five strange symbols. These symbols hold the key to unlocking the door, but the solution lies scattered throughout the Acasa Marshes.
To start the mystery, you’ll need the Notebook – Symbol Research, which provides essential clues.
Finding the Notebook
- Exit Jova from the north and head toward the ON outpost.
- Continue east toward some ruins enclosed by fencing.
- Along the path, you’ll find a sparkling object on the ground. Interact with it to collect the Notebook – Symbol Research.
- Beware: several Lymbic Entities spawn nearby, so clear them first.
The notebook details the five symbols:
- U-shape
- Lightbulb
- Cartwheel
- V-shape
- Eye
Each symbol can appear as dotted or solid, indicating which torch you must activate at their respective locations.
Where to Find All Symbols in Hell Is Us
There are five torch sites across Acasa Marshes, each tied to one of the door’s symbols. To solve the puzzle, visit each site and activate the correct torch.
1. Jova Sewers – Eye Symbol
- Location: Directly beneath Jova, below the symbol door itself.
- Descend deeper into the sewers until you reach a room with two torches.
- Solution: Activate the Solid Eye (left torch).
2. Western Monument – Lightbulb Symbol
- Location: The large monument in the far south of Acasa Marshes. Enter through the stairs at its base.
- Opposite a locked Lymbic Door, you’ll find the torch wall.
- Solution: Activate the Solid Lightbulb (left torch with smooth rings).
3. Pathem Abbey – Cartwheel Symbol
- Unlock Requirement: Available in Act 2, after placing the Keystone of Grief in the Lymbic Forge.
- Location: Beneath Pathem Abbey, near the Timeloop and Jaffer’s location.
- Solution: Activate the Dotted Cartwheel (right torch).
4. Vigil Training Grounds – U-shape Symbol
- Unlock Requirement: Solve the Martial Lineage Mystery by striking the four glowing pillars in counter-clockwise order to open the area.
- Location: Northeast Acasa Marshes, near the ON vehicle crash site.
- Solution: Activate the Dotted U-shape (left torch).
5. Military Camp Cave – V-shape Symbol
- Location: The locked ON camp east of Jova Village. The gate requires the password 151991, which you receive later in the story.
- Head through the camp and into the cave behind it. Inside, you’ll find torches across from the Vault of Forbidden Knowledge.
- Solution: Activate both V-shape torches.
How to Open the Jova Sewer Door
Once all five torches are correctly activated, return to the sewers of Jova. The large wooden door beneath the well will now be open.
Enlightenment Mystery Rewards
Inside the chamber, you’ll find a trove of powerful items:
- Twin Axes of Grief
- Polearm of Ecstasy
- Crucible of Fire (Passive Relic) – boosts melee damage but increases damage taken, rewarding aggressive play.
Quick Tips for Completing Enlightenment
- Flashlight Required: Some torch rooms are extremely dark; keep your light on.
- Enemy Encounters: Expect Lymbic Entities or weaker enemies at most sites—clear them before interacting with torches.
- Story Progression: You cannot complete this mystery on your first visit to Acasa Marshes; some areas unlock only after progressing in the main story.
