I don't have to much lore/story for this post since I wanna save most of that for a later post where I explain the diffrences between Pegasi and Seraphim (which the character, Radiant Gleam is :3)

Radiant Gleam is the illegitamate child of Shutter Star who is the king of the Seraphim and the gaurdian of life, although she pretty much ran off from that life to go live with her partner Springs' Requiem in Midnight Castle

In this picture she is just flying through skies patrolling around for any creature in need of counseling, typically with magical endeavors like a weird biblically accurate fairy godmother
