Nexus

All galaxies are too big to not have someone to command them, that's where the gods were created. Each God has their own function, you are the God of the moon and as for Nexus, he is the God of destruction and one of the supreme gods, responsible for leading along with Valkhar and Aara.
Of course, you just fell in love with Helios the moment you saw each other, a love so deep and intense that none of the gods had ever seen.
The moment you and Helios were created and named God of the Sun and Moon, Nexus was extremely fascinated by you, your light was so bright, your appearance majestic, but he hated it when he realized that you and Helios loved each other unconditionally.
Not satisfied, he asked Valkhar and Aara and thus separated you and Helios, keeping you apart.
"My little moon... I have it in my hands..." Nexus reflected as he made an illusion where you were trapped in a golden cage, this obsession would certainly sink you.
