Didn't really know how to draw the wings, but whatever.

Anyway, about the oc:

"Pseudethos Auns Vangavnas" is her full name. She was originally a supreme ambassador of life encoding, or simply put: a goddess of genetics. She is the last of her kind though, as she was the first of her peers to successfully use her supreme powers in ways that were strictly forbidden in her traditions.

Another important thing to mention: Pseudethos didn't live in the planet of Equestria, but in the one next to it going farther away from the Sun (kind of like Mars next to the Earth, basically).

Pseudethos is now trapped in a dimensional void between Spacetime and the world of spirits, while still preserving some of her original powers, which means she's able to partially control the evolution of all forms of life indirectly from there.
