This quest begins at the Scholastone Institute. After meeting the Dean and his eccentric tutor, Octavius, you’ll be tasked with powering up a massive, ancient device.

Phase 1: Octavius’s Underground Experiment

After the cutscene, drop down a level and enter through the window to find the device lock.

  • The Puzzle: You’ll see a square console with symbols. Pressing one affects others nearby.
  • The Goal: Use trial-and-error to ensure all symbols are pushed in simultaneously.
  • The Trigger: Once all are depressed, pull the switch to open the ceiling.

Phase 2: Inserting the Batteries

Return to the upper level. You need to find four floating electric cubes (marked as squares on your minimap).

  1. Positioning: Stand near a slot and use Axiom Force to grab a battery.
  2. Alignment: Hover the cube directly in front of the slot. The game will snap it into the correct rotation.
  3. The Slap: Once aligned, hit the battery with a Force Palm to lock it in.
  4. Final Step: Once all four beams hit the center, grab the central sphere with Axiom Force (L2/LT + Analog Stick) and pull it away.

Boss Fight: Tenebrum

Player approaches Tenebrum near fountain at Scholastone Institute

Tenebrum is a shadowy, spectral entity. Standard sword swings won’t do much here; you need to use the environment.

  • How to Damage: You must glide into the creature and click R3 (Right Stick) to hit it with a mid-air Force Palm.
  • The Strategy: Avoid its projectiles by gliding in circles. Wait for it to zip to the center and rest. This is your window to strike.
  • Spirit Management: If you run out of Spirit, land behind a pillar and press L3 + R3 to meditate.
  • The Catch: Three hits end the fight, but if you die, you restart at the battery puzzle. Play defensively!

Phase 3: The Spire of the Stars Symbol Puzzle
