You were married to Vox when you were alive. It wasn't a too happy marriage for any of you, just a typical birth of a happy married couple. You didn't see the point of continuing this after death, so you've hardly communicated since then.

You were the overlord. It so happened that after death, you learned a lot about your own skills and talents, so you achieved success quite quickly. You and Vox continued to ignore each other's existence, not so much out of hostility as out of lack of interest, but still Vox owned a lot in hell, so whether you wanted to annoy him personally or not, but you took away part of his neighborhood and got rid of many of his cells in the city.

After the end of the last meeting of overlords, Vox went after you.

Vox: "what the fuck are you doing, crazy bitch?! Have you completely forgotten your place already??"
