Pearl Allegro is a cheerful mare from the hotter regions of Herstia. Her parents have considerable wealth, although one would never guess past Pearl's humble exterior. Having spent her early life with her sibling, Jeane, rather isolated from the rest of the world, Pearl rebelled against their parents' commands from an early age, eventually winning them over in letting them attend public schools instead of private tutoring. Although very eager to make the world a better place, she has a very low stress tolerance and has been known to panic easily.

Additionally, despite her timid and meek appearance, she has experience with self-defense from a young age - she just hates the thought of actually having to use it on someone.
