Dark Heresy: The Daemon Bonded
A daemon with many shapes
Mephistopheles appears in many guises. And possesses many many names. A daemon as old as it tends to collect them. Its forms tend to be clad in black; be it cloth, fur or scales.
Soul taker, she-who-waits, The Clerk, kitty kitty kitty, and Biting Mist, are but a few of the names it takes pride in possessing. Saying the name ‘Mephistopheles’ has proven fatal for at least one prisoner – as they were scoured by warp energy from the inside out upon speaking it.
Each player needs some kind of connection to this daemon; be it pact, a meeting, or via parents (perhaps the notable deed done by your parents was slaying it, or perhaps they were slain by it).
