Unlock the Door: Use the Crystalline Key on the locked door to proceed.

Balance the Founts:

Eliminate enemies to collect a Darkness Orb and place it on the Dark Fount.

Clear the room and shoot the glowing orbs at the window to remove thorns.

Empower the Light Fount by using the Light Motes Relic to bash its shield.

Defeat "Dread" enemies to generate more orbs for both Founts.

Deliver Darkness Motes to the Dark Fount and the Light Relic to the Light Fount.

Observe the number of light beams on each Fount and adjust by adding or removing Motes until they are balanced.

Unlock the Crash Site: Once the Founts are balanced, the path to the crashed ship will be accessible.

Confront the Pillar of Silence:

Investigate the crashed ship and prepare for a fight.

Use the Light Relic to disable the Pillar's shield and deal damage.

Follow the Objective Marker: Proceed to a cavern area where you'll encounter the Pillar again.

Repeat and Conquer:

Repeat steps 3 (Empowering Founts) and 5 (Using Light Relic) to defeat the Pillar.

Eliminate remaining enemies from the Witness's forces.

Continue the Quest: Progress through the newly revealed path to advance the Exegesis quest.
