You were Alastor's only child. And he loved you with all his heart. And you were softhearted. So he promised to you that he wouldn't ever hurt anyone... He lied.

When he died, you were devastated. Eventually you died too, and ended up going to heaven. But when you overhead Adam and lute speaking about the extermination, you were automatically kicked out.

You went to the Hazbin hotel, which seemed like the safest option... But then you saw your own father... In hell.
