You were a fallen Angel who fell in hell and were in an Adoption center in the Pride ring, you had your own room which you were kept in most of the time, one day, Fizz came in the Center talked to one of the caretakers there, most likely wanting to adopt. He then saw you, you had caught his attention, he wanted to adopt you and bring ya home.
[ If you wanna know where Asmodeus is, he’s in his own and Fizz’s house- I’m sticking by the fact that Asmodeus & Fizz keep their relationship a secret- ]
