Rescue Pope, defeat Hedron Parallel in the Unknown, then return to Pope in the Oldest House lobby and finish your conversation with her.
Entering the next sector triggers the completion notice for The House in Distress, and The Hedron Link, a Main Story quest, begins after it finishes. Your first move is rescuing Emily Pope in Prime Candidate Training. After the dimensional vision, take the Oldest House elevator back to the main lobby.

Clear the High Risk Chamber
Continue through the damaged observation rooms and corridors, force open the High Risk Chamber’s hydraulic door, and search the lab rooms for the inner secure door.

STEP 4/4
100%
Enter the Director Training tunnel
Fight the resonant enemies with telekinetic strikes and melee bursts, then move into the Director Training access tunnel beyond the cleared chamber.
The Hedron enemy tutorial warns that these foes resist Raw damage. The telekinetic strikes and melee bursts carry you through this encounter, but the warning does not identify either attack as a special damage counter.

Save the Rangers and reach Emily Pope
STEP 1/4
25%
Drop into the main rotunda
Leave the access tunnel and drop into the central hall, where FBC Rangers are already pinned down by resonant enemies.
STEP 2/4

Clear the attackers
Use psychic attacks against the enemies in the rotunda until the Rangers are safe, then collect the resources they drop.
STEP 3/4

Contact Pope through the intercom
At the sealed security door near the Main Test Chamber, use the intercom and continue speaking with Emily Pope until an order is given to unlock the door for Dylan.

STEP 4/4
100%
Enter the safe room
Go through the opened door to meet Pope and her squad. Continue the conversation about the Hedron patterning as Pope opens the adjoining sector and your objective changes to Sever the Hedron Link.
After the rotunda fight, 1 Talent Point appeared during the recorded run.
After the rotunda fight and before using the intercom, search the side rooms and upper galleries for remaining threats and loot, and the nearby offices for collectibles. Explore the second-level catwalks and the offices above the hall. Return to the main hall when you are done. Items recorded across the run include Living Shard, Source, Edible Glob, Fungal Growth, Patterned Thought, Ordered Image and Hedron Aggregate – Apex.
You can check the updated Quest Log and Inventory before heading onward. The Level 1 Keycard tooltip says it opens FBC clearance level 1 doors and was borrowed from Aristh’s desk in the Field Office.
Cross the Main Test Chamber and reach the Unknown
STEP 1/5
20%
Climb into the Main Test Chamber
Take the broad staircase into the chamber, then follow the upper route toward Central Executive.
STEP 2/5
40%
Cross the flooded corridor
Move through the shifting architecture, fight the resonant enemies along the interior courtyard path, and climb the staircases. Clear the enemies arriving on the upper landing with telekinetic blasts.
STEP 3/5
60%
Enter the distorted void
Follow the red-carpeted exit, jump across its floating platforms, then use flight and dashes between hovering debris to reach the raised doorway.

STEP 4/5
80%
Follow the red carpet through the Unknown
Pass through the doorway and continue along the carpet through shifting stone halls, platforms and stairs to the final gateway and suspended terrace.
STEP 5/5
100%
Head toward the Hedron anomaly
From the terrace, cross the floating golden walkways toward the anomaly on the broken skyline and enter the distorted aperture. Follow the path toward the floating statue head, continue through the hall and climb the geometric terrain.
The suspended terrace is where the UNKNOWN location banner appears. You can open the map here to locate the Unknown sector before crossing toward the core.

Defeat Hedron Parallel
The health bar names the boss Hedron Parallel. Its arena floats and shifts, with resonant gear formations around the boss.

STEP 1/4
25%
Evade the opening volleys
Dodge the swarm’s golden orbs, counter with telekinetic attacks, strike the orbiting formations, and retreat to cover.
STEP 2/4
50%
Renew your attack from the white platform
Use the white platform as a position for another assault, evading projectile volleys while firing ranged blasts into the swarm.
STEP 3/4
75%
Move around the boss cluster
Jump between platforms to change position and avoid incoming energy beams, then repeatedly hit the core with focused kinetic attacks.

STEP 4/4
100%
Break the link
Keep attacking until the finishing blow shatters Hedron Parallel and the dimensional vision plays out. You return to the rooftop terrace with Report to Pope as your objective.
Move between platforms when energy beams threaten your position, then resume focused attacks on the core.

Return to Pope and finish The Hedron Link
You’ve damaged the Hedron’s link, but more links remain. Before you leave the terrace, Zoe radios Dylan. Dylan suppressed another flare-up. He can hurt the links, and cutting each one gives him a chance to practice suppressing those flare-ups. Pope wants to hear what happened; she’s back in the Oldest House lobby.
STEP 1/4
25%
Return to the lobby
After the dimensional vision, check the map and Quest Log for your return journey, then take the Oldest House elevator down to the main lobby. Approach Emily Pope beside the briefing boards in the central room, by the anomaly analysis boards.
STEP 2/4
50%
Debrief Pope
Tell Pope how Dylan disrupted the Hedron’s link, severing its connection between dimensions. Choose the dialogue about Dylan’s condition and the Hedron’s threat, then ask whether the entity can be destroyed. The conversation turns to what happened to Jesse Faden and Pope’s role as Acting Director.

STEP 3/4
75%
Agree on the next move
Work out a plan with Pope to defeat the remaining links. Dylan commits to severing the Hedron’s connections to his dimension with the FBC’s promised full support. Getting too close to the Hedron could let the Hiss take control of him.
STEP 4/4
100%
Finish the conversation
Finish talking to complete The Hedron Link and unlock The First Link trophy. Check the updated Quest Log afterward: your new objectives include the next main quest, Sever the Hedron Links, and the newly available side quest, Pope’s Research.
Severing that link lets the Oldest House stabilize independently, and the evacuation has been called off. The remaining connections are next.
