Febronia

Febronia is a supporting character in the Xenosaga series. She is a realian that Shion knew when she was a child.

Episode I
Febronia appears very briefly as the last thing that Virgil sees before he dies after being shot by KOS-MOS. Febronia appears herself to Shion and the others far later in the game when they make their way into the Encephalon, to Old Miltia. She appears within a stone church. She claims she longed for it to be a place where Realians could find peace. Shion recognizes Febronia and quickly flashes back to her being eaten by several other beings. She claims she knows her, but says she doesn't want to remember. Febronia has Shion and the others follow her into a room in the back where she claims they will come face to face with themselves. This brings them to the Acute Neurosis Treatment Facility, where Shion's mother was being held when she was a child. After the group defeats the gnosis Tiamat, Shion appears in a field with a tree where she sees Febronia accompanying two young girls, her "sisters" Cecily and Cathe. Febronia tells her that isn't the real her, and this field is an illusion created for Cecily and Cathe and that she's showing it to them using KOS-MOS' Encephalon construction abilities. She claims her sisters are trapped by a binding spell used by mankind to control the Zohar. She requests that Shion release them.

Episode II
Febronia appears to Shion while she is on board the Dämmerung. She appears in a vision along with the Zohar and explains this is a cage her sisters are held in. She asks Shion to free them and lift the curse mankind has placed upon them. When Shion and the others arrive at the Zohar Isolation Area, finding Cecily and Cathe, Shion hears Febronia's voice again, asking her to set them free.
