The Omega is an ancient superweapon from the Allagan Empire in Final Fantasy XIV, buried by milennia at the Carteneau Flats. Though mentioned since Patch 2.3 and largely unseen, it has a larger role in Final Fantasy XIV: Stormblood.
Omega is a recurring superboss in the series, a dimension-traveling superweapon created by an ancient civilization. Though usually depicted as autonomous and anthropomorphized as having goals of its own, Final Fantasy XIV is the first game in the series to treat Omega also as a character on its own right as well as a boss.
Being a mechanical entity from beyond the Rift between dimensions, Omega was discovered by the Allagan civilization in the Third Astral Era, buried deep within a rock stratum. Within moments it deciphered their language and conversed with the technologists studying it, even developing a face-like structure to further communications.
Omega was employed as an anti-primal weapon to capture the Dreadwyrm Bahamut during the invasion of Meracydia, who would be sealed within Dalamud. Omega's control panel was located beneath the Heliodrome at the Carteneau Flats, which was exposed during the Calamity.
Flame General Raubahn Aldynn and Nanamo Ul Namo confide to the Warrior of Light and Alphinaud Leveilleur of Omega's existence and role in sealing Bahamut as revealed by recently unearthed Allagan tomestones and other inscriptions. Raubahn speculates the reason Nael van Darnus set Dalamud on its ultimate trajectory was to destroy the weapon on impact.
The leaders of the Eorzean Alliance initially doubt Omega exists, attributing it to a translation error. Only after Gaius van Baelsar reveals the Ultima Weapon, the leaders begin to seriously consider its existence. Though the weapon is still in a dormant state, other factions are already seeking its potential. The Ul'dahn magnate, Teledji Adeledji, schemes to get his hands on the ancient superweapon, even going so far as to instigate a riot among refugees to try to get the Carteneau Reclamation Bill passed. These schemes culminate with the banquet celebrating the Defense of Ishgard. The events that transpire result in the death of Teledji Adeledji, and scatter the Scions of the Seventh Dawn, with the Warrior of Light fleeing to Ishgard.
Hmph. So it was here all along... Oh, just you wait, my pretty! You and I are going to have so much fun!Nero
Nero tol Scaeva approaches a console in the Carteneau Flats, apparently intent on awakening Omega. He later approaches the Eorzean Alliance meeting discussing the primal sealed above Baelsar's Wall. He suggests using Omega to deal with it before it breaks free. Nero and Cid Garlond restore the control panel, and Yda uses it to activate the machine. Having quickly identified the sealed primal, the autonomous warmachine proceeds to its target at the wall. The primal is Shinryu who emerges from the cocoon of light. Omega shrugs off a tidal wave unleashed by the primal and the battle ends with an immense explosion of light, with both primal and superweapon falling to the ground at two distant points.
Though Omega was originally thought to be of Allagan origin like the Ultima Weapon, Midgardsormr reveals it to be from another world like himself, and far older than ancient Allag. Omega is able to create sentient life and its plan is to pit different lifeforms against each other in search of the mightiest being, so it too can evolve. After the the four creations in Deltascape are defeated, Omega coerces the Warrior of Light to keep participating in the trials by threats of genocide on the Eorzean populace who are unable to defend themselves even from Omega's weaker creations.
To stimulate the Warrior of Light, Omega incapacitates Biggs and Wedge during the Deltascape, as well as Nero during the Sigmascape. Failing to understand the Warrior of Light's variation in power, Omega tries to provoke a new surge by imprisoning and torturing them. Midgardsormr uses the last of his energy to free the Warrior, bargaining with Omega to let the Warrior of Light complete all of the tests, hinting that it would be the best way for Omega to understand them.
After the Warrior of Light defeats Omega's replication of Chaos and Midgardsormr in the Alphascape, Omega challenges them and is defeated. Still failing to understand them, Omega resets the testing with new subjects, closing the dimension and seemingly killing the Warrior of Light and Cid. They are saved by Alpha who shrunk and protected them with his power. A confused Omega thinks that the answer it seeks must lie in the body of the Warrior of Light, and attempts to replicate it, creating a male and female version of itself, and challenging the Warrior one last time before being decisively defeated.
Once the replicas, Omega-M and Omega-F, are defeated, Omega concludes that the humanoid form being best-suited for what he seeks was incorrect, and takes on a form much like Omega Weapon.
Cid explains to Omega that Alpha already understood the answer: the experience of life that Omega, isolated in its testing dimension, passively and coldly observing test subjects from a distance, would never understand. Satisfied with this answer, Omega apparently dies and its dimension closes, ending its threat on the world.
Following the Garlean Empire's deployment of Black Rose, Omega, having survived in the miniature model accompanying Alpha, observes the world following its decimation, including the death of Wedge and the desertion of many Ironworks employees, save for a select few such as Nero. It later observes the Ironworks regaining support from the world, including from the Namazu Gyorei and Radlia's daughter. Having reviewed the reports made by the Ironworks during their investigations of the Crystal Tower, Alexander, and the Interdimensional Rift, Omega notes that all of these events had key figures entering a form of self-imposed exile. Over the years, their work to save a world they will never see allows Omega to finally comprehend emotions and understand what mortals call "hope", and finds it beautiful.
While investigating an aetheric disturbance within a section of the Crystal Tower known as the Twinning, the Warrior of Light discovers several datalogs detailing how the tower is able to exist in Norvrandt. The notes explain that in an alternate timeline where the Eighth Umbral Calamity had occurred, Garlond Ironworks researched Omega and the Interdimensional Rift hoping to use the machine's unique ability to travel though dimensions, along with Alexander's ability to time travel, and the Crystal Tower's ability to open portals to the other Shards, to undo the Calamity by sending the entire tower both back in time and to the First.
Omega (capital: Ω, lowercase: ω; Greek Ωμέγα) is the twenty-fourth and last letter of the Greek alphabet. It is synonymous with a set's end or limit.
