Her title goes by the Goose Queen,
She is the goddess of myths and folklore.
A Mother-like figure that possesses great power over the world's destinies. A powerful being that holds the essence of life in the egg-shaped gems. Her scepter is her main weapon, although she can conjure great and powerful magic out of her own hands. Her egg gems are her main form of attack, with each egg containing a somewhat limited scale version of the universe. If an enemy manages to interfere her, she can entrap an enemy with one of her gems. Or blow up a "new universe" on the target.
although she can travel through universes and foresee the future with accuracy, she does not hold power and dominion in the essence of time.
Her egg-like gems also serves as a form of "hero creator". Creating heroic characters and breathing new life out of a single egg.
She is also responsible for the fairy godmother's creation. And the legendary weapons that were featured in folklore and mythology.
The Goose Queen can shape shift herself into a goose or any disguise depending on the location. The goose form is her primary disguise form.
Despite her immense power, she is merciful, motherly, and benevolent walking with humanity and it's authors. She cares for humanity and their stories especially stories of heroism. She refuses to use her power on enacting destruction, ever if her power can destroy things on an almost cosmic level.
