Demonheart: The Cursed Trial

You wake up in a strange place, only to realize you have been abducted along with seven other people. A city guard, a royal soldier, a witch, a bard, a librarian and two criminals... What force could be powerful enough to bring you all against your will, and why?

Then a demonspawn appears, giving everyone a "friendly warning" that some demonhearts are among you - people blessed with regeneration, but cursed to be hunted by everyone else. Being a demonheart yourself, you don't want the others to find out.

Mysterious deaths start happening, and the survivors need to identify the murderer. As former friends betray one another, someone benefits. Who is the traitor?
