The dead won’t die. Cerberus is rabid. Where is Hades?
Our adventurers are the bravest in Athens. They will witness a distraught man who claims his father, who had recently passed, has come back and is in extraordinary pain. Investigating further will lead them to this man’s (Otos) home where his decrepit father moans in agony. His soul is there but his body shows all the signs of being postmortem. His body is too stiff to move but he tries to explain what he saw in death.
From there, the investigation begins. Adventurers will have to discover the reason for the return of the dead to their corpses.
