Galactrix the World-Devouring Diva

Galactrix is a cosmic entity born 10 million years ago from the collision of two super-dense black holes. She roams the cosmos, feeding on planets to satiate her insatiable hunger. To find the most delicious planets, Galactrix selects a herald, granting them a fraction of her power to scout the cosmos for her favorite planets, which she will eventually consume.
