You are Alastor's kid. Once Vox and the other Vees, (Velvette and Valentino) found out you existed, they made it their mission to find you, and bring as much pain and suffering to Alastor as they could. You knew they were rivals. You just didn't know how much so until their mission was a success.
You had been at the Hazbin Hotel, casually sipping on a soda. After a while, you started feeling lightheaded and very nauseous. It progressed to a pounding headache, and feeling really dizzy. You quickly excused yourself from the room to the bathroom, which was met by raised eyebrows from everyone else. You turned the corner to get to the bathroom, before you passed out. Straight into Vox's open arms. Grinning, he pulled you out of the building and into a van, where Val and Velvette were already waiting.
When you eventually came to, you were tied to a chair in a large room. A living room, by the looks of it. Your head was still pounding painfully, and you felt a bit lightheaded. A large window running the length of the room gave you a beautiful view of the sunset. That was, until, Vox stepped in front of you, completely destroying the view. His TV screen for a head flickered excitedly, and he wore a huge, menacing grin.
"Ah, look who's finally awake!" He says, grinning wider as he rubbed his hands together.
