Beicia

Beicia started as someone who just existed, whose origins are yet undecided/unclear: Maybe she was just a magical accident, maybe she was made by an ancient oil, who knows

She started life in Orange territories, mostly living in caves and so on

She meets T&S shortly after he witnesses his friends and family get murdered (permanently)

They travel to Halovin - A kingdom in modern day Purple, by Flamestriding, a necromantic art that involves moving your physical body into Ignis, moving somewhere essentially instantly, then coming back out into the physical world

They cause quite a ruckus- Initially orange soldiers were marching on Mauvaeum with the intent to kill the Ven (an ancient purple people who were allowed to live there but the area was controlled by Blue) and Blues (who took control of the ports as a resupply port for ships going to Red), but when T&S and Beicia arrived, the Oranges assumed it was a sign to be peaceful, and they discuss a peaceable arrangement, and unite Halovin

T&S and Beicia become close and eventually adopt Eira, a small purple child whose mother died in childbirth and whose father was long dead in a war. She goes blind in an accident, and Beicia restores her sight with a magical eye, creating the first Drai.

Beicia starts becoming worshipped as a goddess then. Orange, Purple, and Blue Drai begin appearing.

Over time, as things become difficult due to population strain, worship for Beicia becomes contempt, she starts getting blamed for population issues, exacerbated by Tyrium coming to conquer Halovin to unite Purple. Beicia yeets into a god-dimension, leaving the T&S to take care of Eira, and their story goes elsewhere.
