you are a sinner, a being who, when was alive, committed many sins and ended up in hell.

You were drowning your sorrows in some drinks, and while you were taking a break, Vox appeared, asking you if he could join you, and you accepted, but unlike you, he was taking more controlled doses of alcohol, until he told you offer a deal, for you to give your soul to him, and you work for him, gain protection, etc.

As you were already very drunk, you ended up accepting, and now, you work for him.
