Etro's Gate, also known as the Unseen Gate and the Door of Souls (魂の扉, Tamashii no Tobira?), is a gateway to the afterlife in Fabula Nova Crystallis: Final Fantasy. It is operated by the goddess Etro. The gate resembles an eye in appearance.
According to the official mythology, the universe is divided in two halves: the visible world, or the world of the living, and the unseen realm, or the world of the dead; if the balance between the two worlds is broken, the universe is in danger of collapsing. Despite this, Bhunivelze and his fal'Cie creations are compelled to find the gate to ensure the former becomes immortal.

XII. The Door of SoulsEdit
When our earthly vessels meet their end, the souls they housed must leave this world. Would the path of their migration not be the same one as our departed gods? Must they not pass through the same doorway the Divine employed to reach that place that lies beyond?
If this is the case, it stands to reason that, should a great many lives at once be cut short, a flood of souls would surge through the aforementioned portal. The Door would be thrown wide, and perhaps we might even glimpse the gleaming light of Divinity beyond.

XIII. Fabula Nova CrystallisEdit
Children of Hallowed Pulse scour earth, searching substance for the Door. Those of Fell Lindzei harvest souls, combing ether for the same. So have I seen.
The Door, once shut, was locked away, with despair its secret key; sacrifice, the one hope of seeing it unsealed.
When the twilight of the gods at last descends upon this world, what emerges from the unseeable expanse beyond that Door will be but music, and that devoid of words: the lamentations of the Goddess Etro, as She sobs Her song of grief.

The instant Etro's Gate opened, a world-devouring darkness slipped through from Valhalla. The goddess turned back the river of time and that terrible darkness—the Unseen chaos—was sealed away.
Her power exhausted, Etro fell into a sleep from which she would never awaken. It was Lightning who sensed that someone meant to exploit that weakness and destroy the goddess for good. She learned of the man named Caius Ballad.
If the goddess is destroyed, the chaos of the Unseen Realm would be unleashed, and the mortal realm devoured by Valhalla. Lightning decided to stand and fight, to protect Etro and see her benevolent will upheld.
Upon a person's death, what could be called their "soul", turns into crystal energy and passes through the gate to the afterlife. The fal'Cie, being machines, lack souls and thus cannot access Etro's Gate. The fal'Cie believe the Maker, the god who created the world, has departed beyond Etro's Gate, and devise a plan to send as much crystal energy through it as possible by destroying Cocoon, believing it would force Etro's Gate wide open and reunite them with their Maker while the world would be reborn. This would destroy the balance of the world, and Etro stopped the first attempt during the War of Transgression by turning the l'Cie tasked with destroying Cocoon into crystal.
Lightning's group hears of the fal'Cie's plan from Cid Raines in the Fifth Ark. Later, before ascending to Edenhall, the party observes crystal energy glimmering in the air. They wonder of its significance and Barthandelus appears in the guise of Galenth Dysley, explaining it means the Maker is soon to return. As Barthandelus disappears inside the tower above Edenhall Etro's Gate opens on the sky of Eden.
After the party defeats Orphan the lights of Cocoon go out, all but of the mysterious light that is Etro's Gate. As Ragnarok crystallizes the world of Cocoon, Etro frees the Pulse and Cocoon l'Cie from their fate before the gate closes.
Due to Etro freeing the l'Cie of their fate, chaos leaks into the Visible World and drags Lightning through the Historia Crux to Valhalla while warping the timeline. During Lightning's battle with Caius Ballad in Valhalla, Noel Kreiss emerges from Etro's Gate that opens over Etro's Temple, but Lightning rescues him by summoning Bahamut to catch him mid-air. When Noel enters his dream world and relives his final days in the Dying World, he prays for Etro to gift him with the power of chaos so he can follow Caius to Valhalla.
A light opens on the sky and he is pulled towards it, presumed to be Etro's Gate, but before he can enter it he is woken up by Serah. When Lightning meets with Noel and Serah at New Bodhum in the year 700 AF, she tells them the nature of Etro's Gate and how Caius is intent on finishing what the Cocoon fal'Cie had started in the slaughter of Cocoon's people to force Etro's Gate wide open.
After defeating Caius in Valhalla and solving the final paradox, Serah and Noel emerge from the Unseen Realm using a Time Gate. Etro's Gate is smashed apart by the chaos that is no longer bound by Etro, and chaos enters the mortal realm. With Etro's Gate no longer present to act as a gateway between the worlds of living and dead, Valhalla and Gran Pulse merge into a new world, which time becomes known as Nova Chrysalia.
Arecia Al-Rashia's reasons for creating Class Zero is to use the power of a soul with great power to force Etro's Gate to open. Serving Lindzei in opposite to Arecia being a servant of Pulse, Gala believes the sacrifice of billions would be a better method, and sends his forces to slaughter everyone when Finis begins.
After they both fail, Arecia resets the world and prepares for the next experiment. The two have been continuing their experiment 600,104,972 times before Arecia finally decides to end it and leave Orience forever.
It is said those who die will meet Etro when she opens the gate to give the departed souls entry to the afterlife. Near-death experiences are steeped in the legends and lore of Etro, and it is told that when one is dying and one's soul pulls back from the borders of mortality into the afterlife, upon seeing the light of the opening gate they gain the graces of the Kingdom of the Dead and are bestowed with a great power. Noctis Lucis Caelum and Stella Nox Fleuret are said to have this blessing through their experiences.
"Etro's Gate" (エトロの門, Etoro no Mon?) is a track that appears in Final Fantasy XIII-2 and was composed by Masashi Hamauzu. It plays during the FMV of Lightning being trapped in a paradox and falling through the Historia Crux. It has the slow-paced melody of "Blinded By Light" included in several moments.
- A replica of Etro's Gate is seen behind the final form of Orphan in Final Fantasy XIII. During battle, the camera can move in a way to let the player get a view of the structure, but the edges of it can be seen from any angle. When viewed from the front Orphan's body and the gate form the appearance of an eye.
- The presence of Etro's Gate appears to be accompanied by flashing crystal shards in the air. This is seen in Final Fantasy XIII when crystals begin to glow in the air as Etro's Gate opens in the sky. The same phenomenon is seen in Final Fantasy XIII-2, where the air glimmers with crystals when Lightning is met at the pier in New Bodhum in 700 AF, having entered from Valhalla. The same phenomenon also appears in Final Fantasy XV, where the glimmering crystals have been seen in trailers, and the legends say it is the light that can be seen when someone is near death.
