Nyx Daughter of the Bright and Terrible

Nyx is the child of my character KB, personification of the most volatile force in the universe, the "big bang" encapsulated into form so he can romp the earth and make mischief. Lucifer his guardian angel takes him into his light form and together with KB's human wife , Sud who is enamored by his heat, they create a child she names Nyx. Nyx becomes the most powerful known energy in the universe, so much so even the gods are afraid of her! Hu the Great Alchemist is also in awe of her! Sud died in childbirth so the part of Nyx that was human craved attention from her father, but he being KB was not always around for her. 

Heartha was.

 Heartha helped raise her, bonding with her as one of her own. Sud afterall had been her human daughter making Nyx her granddaughter. Hu doted on her as any grandfather would, both he and Heartha were loving grandparents to her...but being part of KB in Lucifer's form she had a strong desire for dangerous play. She felt bad about this, her human nature had come to love Hu, Heartha, their children and all they had created together, so she left the earth to explore the cosmos and make worlds of her own. She is known as the most powerful deity ever created. She has the light within her, but how will she choose to use it?

 Any way she wants.
