Gentiana

Shiva lives in the world as Gentiana, the High Messenger who stays by the Oracle Lunafreya Nox Fleuret's side. Whereas the Oracle can commune with the gods to deliver mankind's message to them, Gentiana does the same for the gods. Shiva seems able to co-exist in multiple bodies, as when summoned by Noctis, she appears as numerous glacial pixies, and when her colossal ice goddess body was felled by the Niflheim Empire, Gentiana was already living at Fenestala Manor in Tenebrae. It has been implied that the reason Shiva now appears in a smaller form is because she was previously killed. Whether Gentiana is her own person whose body Shiva is "borrowing" after losing her corporeal body, or whether the two were always the same person, is unknown. Shiva's profile describes her thusly: "She is the true form of the spirit incarnate in Gentiana, using both her celestial form and material body to cure Eos of the Starscourge."
