Ages ago, when the first universe formed, the Chizarans appeared. Within the first generation, the entire race had become gods. They spent the first years of their history exploring the limits of their power. They were immortal, masters of space-time, creators of anything they wanted, and worshiped. Unfortunately, they found that having all that power, coupled with their immortality, was boring. After a period of stagnation, five Chizaran women discovered that other races had never interacted with one another, so they made the Verse Vs. Verse Rumble Royale, a tournament that takes fighters from different universes and pits them together in a fighting match of their choosing. Because it was so popular for the Chizarans, the five women were elected as the rulers of the entire race. They decided to be labeled as Princesses as it sound more free than Queens. Each woman is leader of a certain aspect of Chizaran culture.

Grilcaldo's a special case. She's actually one part of the greater grey princess of Chizara. When the original grey princess, Grisalmee, got the remaining aspects, she split herself into four identical copies of herself so she could manage the remaining four aspects more effectively. All four of them are mentally linked with one another, so one can remember what the other three have experienced, sometimes leading to confusion. Unlike most copies, all four grey princesses get along splendidly with one another. Grilcaldo is the warm-grey princess of the Grey Princess Quartet and leads all matters related to fire.
