She's literally called "mother that creates/births the planet" I'm sure once in FGO. Don't forget the pure fairies are far stronger than the gods. Gods are nothing but potential vessels for the fae. Like humans. They can mimic and create bodies like that. While the real form of the fae are the primordial forces of nature.

The pure fae not the false fae, or those fallen out their roles like happened in LB6. Morrigan, THE head mother goddess of an entire pantheon is casually one of her vessels. The sister of King Arthur is another.

Morgan is Vivian too, who loved Arthur as a mother. Morgan didn't save Artoria but her Vivian side did.
