Prologue...

AU: Post Season Two

The Devil asked me how I knew my way around the Halls of Hell. I told him I didn't need a map for the darkness I knew so well.

Lucifer has decided to hold a competition where seven demons will compete to become the Prince(ss) of Hell. At 145 years old, does Ciel have what it takes to become the Heir of Hell?

The title is Latin for "The Devil's Heir".
