To reach the underground lock device switch, you must go to the north-east corner of the plaza where the quest started. Follow the path with the lanterns, it leads underground.
After reaching the bottom you must interact with the “hatch”, it looks like a wall panel.
Here you must solve a puzzle by pushing the hatch buttons. You can press Dpad Left/Right to change which button to press. There are many solutions but an easy method is to press the 4 corner buttons, then press the middle button.
Hatch Puzzle Solution:

- Press bottom right corner button
- Press bottom left corner button
- Press top right corner button
- Press middle button
If you’ve already interacted, you can back out to reset the puzzle and interact with it again.
When all buttons glow up, you’ve solved it correctly:
After solving the puzzle, interact with the same wall again to use the handle. You’ll get a cutscene where the machine boots up.
Insert the batteries to activate the device
Go back upstairs to where the quest started, in the round plaza. There you will find 4 pillars with cubes in front of them – these are the batteries.
You must grab the batteries with Axiom Force (hold

While the cube floats in front of the pillar, press

to use Force Palm.
This will punch the battery into the pillar. Repeat this for all 4 batteries, each will shine a power beam at the device in the middle.

To defeat Tenebrum you must hit him multiple times with Force Palm while flying in the air: Double press

to perform Force Palm. Hitting Tenebrum can be tricky because he flies around constantly.
It’s best to attack when he stays in the middle to charge up an attack. If you get hit by his projectiles you will fall down and take fall damage, but can heal back with

If you run out of Spirit, hold
