The Aetherochemical Research Facility is a Dungeon Dungeon and the final dungeon in the main scenario storyline of Final Fantasy XIV: Heavensward. The dungeon is an Allagan research facility containing the Warring Triad central controls and houses many Allagan defense systems.

The Aetherochemical Research Facility contains no loot.

Story[]

Your pursuit of the archbishop has brought you to the Aetherochemical Research Facility, at the heart of the floating isle of Azys Lla. However, he and his knights are not the only threat for which you must be prepared; shortly before your arrival, the VIth Imperial Legion entered the facility in search of the secret to mastering primals, and their presence will serve to complicate matters. With multiple factions and their ambitions set on a collision course, your mission promises to be fraught with danger and uncertainty both.

In-game Description

Upon meeting with the great wyrm Tiamat imprisoned in Azys Lla, the Warrior of Light's crystal of fire is restored and the Blessing of Light reactivates. Having now recognized the adventurer as Hydaelyn's champion, Midgardsormr vows to act as their wings and flies to the Flagship in pursuit of Archbishop Thordan VII.

Neurolink Nacelle[]

The party encounters the Ascians Lahabrea and Igeyorhm at the Neurolink Nacelle. Both Ascians will always be targettable and heal each other to keep their health equalized. They will each summon fire and ice orbs. Lahabrea's fire orbs explode in large AoE circles, while Igeyorhm's ice orbs detonate in donut circles. They can also tether two of their orbs together to create a bigger AoE.

Lahabrea will cast End of Days, a line stack marker that requires players to line up to mitigate damage, as well as Dark Fire II, placing purple AoE markers on all players. Igeyorhm will also cast Grip of Night, a frontal cone AoE.

As soon both Ascians reach 0.1% health, a cutscene plays in which he and Igeyorhm will fuse into Ascian Prime.

The Ascian Prime is much more dangerous than Lahabrea or Igeyorhm. At certain points in the fight, he cast Dualstar, combinding the fire and ice orb abilities of Lahabrea and Igeyorhm. Players must eye the tethers to see which orbs will detonate first and adjust acordingly.

Ascian Prime has a tankbuster, Height of Chaos, as well as a raidwade attack, Shadowflare. Ascian Prime will also cast Universal Manipulation which inflicts several status effects that detonate mechanics once they expire, including a stack marker, donut AoEs around all players, and chaining players in pairs.

Ascian Prime will become untargettable and cast Arcane Revelation, siphoning power from a large Arcane Sphere to power up an Ascian Prime's Power gauge. Untargettable shades of Lahabrea and Igeyorhm will attack the party during this DPS check. If Ascian Prime was allowed to reach 100%, his ultimate attack, Annihilation, will wipe the party Other than Ancient Eruption, which places AoE circles underneath all players, the mechanics will repeat until the boss is defeated.

Journal

  • The guidance node has been awaiting your arrival at the Flagship with customary patience.
  • According to the guidance node, you are but a few steps away from your destination. However, it would seem that intruders have been detected ahead. Follow the node towards the heart of the isle, and be ready to defend yourself.
  • You have eliminated the imperial troops and secured the area. Speak with the guidance node to be granted entry to the Aetherochemical Research Facility.
  • Having opened the way to the Aetherochemical Research Facility, the guidance node bids you farewell and deactivates for what might very well be another five millennia. After casting a final glance at Gilly's motionless form, you turn your mind to the challenges of the present. Somewhere within, the archbishop and his knights await. Ready yourself for the worst and continue your pursuit. ※The Aetherochemical Research Facility can be accessed via the Duty Finder.
  • While fighting your way through the Aetherochemical Research Facility, you find yourself face-to-face with Lahabrea and Igeyorhm. in a bid to eliminate you, the Ascians attack as one, but with Hydaelyn's blessing restored, you are more than a match for them.
  • Realizing the battle is lost, Igeyorhm attempts to flee, but before she can make good her escape, you destroy her with a blade of Light forged from the Eye's remaining aether. Alas, you are left without the means to strike down Lahabrea. Just when it seems certain that the Ascian will slip through your grasp, the archbishop and his knights arrive, bearing the body of Haldrath... and the Eye's long-lost twin. Having summoned the soul of the legendary King Thordan into himself, the archbishop conjures a divine blade using the power of the second Eye, and summarily executes Lahabrea. Judgment passed, the self-proclaimed god-king duly turns to leave, but not before issuing you a challenge. Answer it, and put an end to his madness once and for all. ※The Singularity Reactor can be accessed via the Duty Finder.
  • At the end of a titanic struggle, you triumph over Thordan and his knights, bringing to an end their deranged dream of founding a new world order.
  • Still breathless from your exertions, you look up to see Estinien, who sullenly collects the Eye and its twin. Alas, in so doing, the dragoon falls prey to Nidhogg's lingering influence and is claimed as a vessel for the great wyrm's rage. No sooner has he departed than the facility begins to collapse around you, prompting Midgardsormr to appear once again, and bear you away to safety. Still reeling from what you have seen, you rejoin your comrades aboard the Excelsior, and are borne back to Ishgard and a hero's welcome. At the airship landing, Midgardsormr addresses Aymeric, and the two speak candidly of the future, their meeting marking the start of the journey towards peace between man and dragon. Some days later, the Holy See makes its long-awaited return to the Eorzean Alliance in an uplifting ceremony attended by the leaders of all four city-states. a fitting reward for your efforts, no doubt, but one that you wish Haurchefant, Ysayle, and Estinien could have seen... Speak with Alphinaud at Fortemps Manor and hear his thoughts on this momentous occasion.
  • Alphinaud is elated that his dream of a unified Eorzea has finally been realized. Though upheaval will invariably accompany the coming changes, he is confident that, with effort, peace and prosperity will follow. Together with your fellow Scions, do your part to see that it is so.
