Gnosis

"I am Seraph Gnosis… My duty is to carry out divine retribution to sinners."

Seraph Gnosis (グノーシス) is one of the second generation Seraphim who were created to fill the gap left by  Micaela  who was promoted to leader of the Seven Archangels, and  Lucifina  who had fallen.

Biography
After collecting the Mithril Ore, Luka, and the party goes to investigate the strange power radiating from the summit of Mt. Saint Amos.

At the peak, they find Micaela, barely alive. Luka has a flashback to his fundamental reality self, and he immediately recognises her as his aunt. Micaela is glad to see Luka, despite her being on the verge of death.

Micaela warns them that the being who put her in this state is still here, and the party promptly feels an even greater power coming from above them, and the world goes dark.

They look to the sky, and they see a deformed angel.

She introduces herself as Gnosis, a member of the second generation of Seraphim. Her duty is to deliver divine judgement to sinners.

When Luka asks if Gnosis did this to Micaela, she admits that she put her in this state, but that Micaela must also bear half of the blame for it. Micaela living out her days on earth caused her power to dwindle and therefore put her in a state where Gnosis could fight her. If Gnosis had fought Micaela while she was still at her full power, Gnosis would have had no chance. She almost feels sorry for Micaela.

This scene will differ substantially from here, depending on whether Luka took Ilias or Alice with him.

If you took Ilias, she will mention that despite Micaela losing a great deal of her power, no other angel should be able to rival her. Ilias is also unaware of any angel by the name of Gnosis, and she asks Gnosis whether she came from a parallel world. Gnosis responds that she cannot assist her at present, but in the future, she will be able to answer all of her questions. Implying there will be the option to pick a faction in the future.

If you took Alice, she insults Gnosis’ cowardice for attacking Micaela only after she was severely weakened. She challenges Gnosis to come down and fight her. Gnosis informs Alice that the current cross-world deviation by her and Luka is at 26%. Although greater than average, it is not at a critical level just yet. However, if she executed each of them right now, chaosisation would accelerate by up to 125%, and the damage caused by it would increase by 67%. Effectively dooming the world. Also, Luka is the son of Marcellus, the man who has deviated more than anyone else from the original timeline. She will not execute Luka because he is the key to finding Marcellus. As much as she wants to execute them, she cannot as the consequences by doing so are too great. In short, the Seraphim can’t intervene directly unless the person in question deviates too much from their own history.

After this, she leaves the world.
