Ghost Revelry Hall in Where Winds Meet hides the Dark Room, a small arena where you confront the Faceless and progress the Unbound Cavern segment of the Accident main story.
Quick answer: In Ghost Revelry Hall, go up to the second floor from the stage and follow the balcony hallway to the final door marked by a lantern-lit balcony and a singing icon; that door is the Dark Room.

Dark Room state: what it is and when it matters
The Dark Room is a mandatory story location tied to the Unbound Cavern “Lost Chapter” inside the Accident main quest in Chapter 2: Universal Furnace. It serves two roles at once: it advances the quest objectives that mention “Go to the Second Floor. Find the ‘Dark Room’ / Trace the source of the song,” and it is the arena for the Faceless mini-boss.
Reaching and clearing the Dark Room is required to push Accident forward toward the Human Market, Prison Depths, Zhuxie Gule, and eventually Dao Lord. The state you are aiming for is simple: the objective switches from finding the Dark Room to defeating the Faceless and then leaving Ghost Revelry Hall.
How to reach Ghost Revelry Hall before you look for the Dark Room
Step 1: Progress Accident until Little Fu flees into the Ash Pit during the confrontation with Lord Shi in Kaifeng. Drop into the Ash Pit area and investigate her footprints to confirm you are on the right trail.
Step 2: Move through the Subterranean Sewer. Follow the tunnel down, deal with the rats, and continue until you see and hear the Bell Ringer. Speak with him, then continue deeper to the chamber where a Nine Mortal Ways disciple (Wang Feng) is held by Unbound Cavern members.
Step 3: Defeat the Unbound Cavern thugs around Wang Feng. After the fight, talk to him to learn that Little Fu ran toward Ghost Revelry Hall. He hands you a key and tells you to open the nearby iron gate and follow the red lanterns.
Step 4: Use the key on the large iron gate, then follow the line of red lanterns through the tunnels to the guarded door of Ghost Revelry Hall. Clear the enemies outside and enter the hall proper.
Step 5: Inside Ghost Revelry Hall, survive the three combat waves in front of the stage. These include basic thugs, an Aureate Pavilion bellbearer with bodyguards, and a shielded opponent that can be cracked with skills like Tai Chi or Stonesplit-aligned weapons. When the waves end, speak to the woman on the stage to update your objective to finding the Dark Room.

Exact Dark Room location on the second floor
Step 1: Stand on the main floor facing the performance stage in Ghost Revelry Hall. From this orientation, go up to the second floor using one of the staircases that rise from the sides of the hall. Both routing descriptions in the game agree on “from the stage” as the reference point, but the reliable pattern is that you must reach the continuous balcony that wraps around the hall.
Step 2: Once you reach the second-floor balcony, start walking the hallway that runs around the whole chamber. Ignore the first doors you see; they are regular rooms or small vignettes and not the target. Continue following the balcony corridor all the way around until you reach the last door on that level.

Step 3: Use two cues to confirm you are at the Dark Room door:
- There is a small balcony outside the door, lit by hanging lanterns.
- A singing icon appears, and you can hear a woman singing from behind the door. The quest step “Trace the source of the song” aligns to this audio marker.
Step 4: Interact with this final door and enter. The interior is dimly lit, with a performance-like setup and a single opponent waiting. This chamber is the Dark Room.
What happens inside the Dark Room (Faceless state and quest update)
Entering the Dark Room immediately locks you into a fight with the Faceless, a “Ghost Mistress of Unbound” type enemy used throughout the Unbound Cavern section.
Step 1: As soon as the encounter begins, focus on surviving her fast strings. Faceless attacks are rapid and can apply Bleed, which chips health quickly if you let her combo continue. Deflection or Assist Deflection is the safest way to empty her Qi bar; alternatively, you can overwhelm her with faster weapons if you maintain stamina.

Step 2: Reduce her health to zero to complete the “Defeat the Faceless” objective tied to the Dark Room. There are no special mechanics other than her speed and Bleed, and the door does not introduce additional enemies during this fight.
Step 3: After she falls, interact with the frightened woman in the corner of the room. You can either stay silent or choose the option to place her somewhere safe. The dialogue choice has narrative flavor but does not alter the structural path of Accident or Unbound Cavern.
Step 4: Leaving the Dark Room and exiting the upper levels of Ghost Revelry Hall updates the Accident objectives to move toward the Human Market (“Leave Ghost Revelry Hall. Search for the ‘Human Market’ / Explore the Unbound Cavern. Find the ‘Human Market’”). At this point, the Dark Room has fulfilled its role and does not need to be revisited for the main progression.

How to tell you have correctly found and cleared the Dark Room
You can verify that you reached the correct room and completed its function through three simple checks:
- The quest text changes from finding the Dark Room or tracing the song to defeating the Faceless, then to speaking with the woman in the corner.
- The Faceless mini-boss no longer respawns in that room after you have fought and defeated her the first time.
- Accident’s objective chain moves on to leaving Ghost Revelry Hall and locating the Human Market and Lord Xiao, rather than pointing you back to the second floor.
Common mistakes when looking for the Dark Room
Several patterns can cause players to miss or misidentify the Dark Room, even after they have full run of Ghost Revelry Hall:
- Stopping at earlier second-floor doors. The first or second rooms off the balcony are decoys with NPCs such as the Mysterious Man or Mysterious Woman. The Dark Room is specifically the last door on the run, not these earlier ones.
- Ignoring the singing icon. The audio cue and on-screen icon are the primary signals that you are in front of the right door. If you do not see or hear singing, keep walking along the balcony.
- Leaving before talking to the corner NPC. Defeating the Faceless alone does not fully clear the Dark Room step. You must also speak to the frightened woman after the fight so the quest can advance to the Human Market objectives.
Once you have used the lantern-lit balcony and singing to pick the final door, and you have defeated the Faceless and spoken to the woman inside, the Dark Room’s role in Accident and Unbound Cavern is complete.
