Fun Fact: The Reason why Zandex is so Big is because She has been eating Over 150 Billion Solar Masses of Hydrogen Gasses and is a Hyperactive Quasar. Fun Note about The Sizes!: The Sizes are based on their Schwarzschild Radius. if you are wondering how Big I am if I were in this, I am around 550 AU since I'm a Red Ultragiant Star.
