Legends of the Vermilion Bird True Flame had been told in the Grace Mainland, and each of them was related to the Sacred Beast Vermilion Bird.

The Sacred Beast Vermilion Bird was a mighty existence in the Immemorial Epoch. It was gifted with the ability to use fire. As the Sacred Beast of Fire class, its supernatural power was eternal. It was one of the most powerful existences of that era. 

Another legend, which got approval from many people, was said to be the nearest to the truth.

Rumors had it that when one of the four Sacred Beasts, Vermilion Bird, left the Grace Mainland, as it didn't know whether or not it could survive in the outer space, it left a wisp of its soul.
