Head to the Hollow to Investigate Porcelumex's Secrets
Talk to the other Proxy to return to the Hollow and continue investigating. You will be teleported back to the closed elevator from the Source of the Obscuras quest.
Use the Elevator to go to the Lower Level
Input the passcode: 110011 to open the closed elevator and gain access to the lower levels.
Investigate the Obscuras
Investigate the Obscuras in the lower level of the warehouse. The Obscuras will all be marked on your map. Afterward, you will investigate the locked door and the clues around the warehouse for the second passcode.
Open the Closed Door
Open the closed door immediately by choosing the Ugh... (Let's just ask Fairy) dialogue option and input the passcode: 011110. You will also need to fight nearby Ethereals on the other side of the locked door.
Find the Elevator's Generator
Interact with the elevator and find its generator on the upper floors by following the objective marker. Proceed with caution, as you will encounter numerous Ethereals along the way.
Find the First Thermosetting Unit Control Device
Control your Proxy at the lower floors and use the Revelation Technique to solve the First Thermosetting Unit Control Device puzzle. You will need to reveal one power line.
Start the Next Generator
Head straight to the next generator and interact with it to start it up, which will activate the elevator.
Find the Second Thermosetting Unit Control Device
Control the Proxy again at the lower floors and use the Revelation Technique to solve the Second Thermosetting Unit Control Device puzzle. You will need to reveal two power lines.
Start up the Last Generator
Head to the last location, defeat the nearby Ethereals, and start up the last generator to access the elevator.
Use the Elevator to go to the Upper Floor
Access the elevator, head up to the upper floor, and regroup with the others. Defeat the Ethereals in the room and investigate the damaged gate.
Enter the Ventilation Duct
Use the Revelation Technique to remove the crates blocking the path and enter the ventilation duct. Inside the ventilation duct, you only need to press the forward button to progress through.
Investigate the Documents Left at the Scene
Investigate the documents in the red colored room with Yuzuha, Manato, and Alice. You learn that the Porcelumex and Exaltists have been working together towards an ulterior motive for quite some time now.
Defeat the White-Haired Ghost Woman
Try to defeat the White-Haired Ghost Woman that suddenly appeared in the room. You won't get to defeat the enemy; you just need to fight it long enough until the exit cutscene occurs.
At the end of the cutscene, you get captured by Ferox and his men.
Escape From the Cell
Escape from the cell by using the Revelation Technique to clear the Miasma and get to the ventilation duct.
Defeat the Sacrifice that Suddenly Appeared
Follow the objective marker to get to the exit, clear the Miasma Tumors, and defeat the enemy that suddenly appeared out of nowhere.
Follow Yuzuha and Escape the Pursuers
Follow Yuzuha to the exit and escape the pursuers. You can skip fighting the enemies that you will encounter during this objective and head straight for the exit.
Return to Meet With Ferox
With everybody gone, return to Ferox as Yuzuha and turn yourself in, and cut a deal with him.
