From publisher blurb:
The Penumbral Vestibule is a 4-hour, one-shot dark fantasy adventure for 1st-level characters, converted for the Black Flag Roleplaying System. This Grim Hollow adventure is set in the world of Etharis, a place of darkness and terrible evil, where goodness is rare and beautiful. In this dark fantasy setting from Ghostfire Gaming, heroes are rarely paragons of justice. They are mortals with foibles and flaws. In turn, villains are rarely avatars of pure evil hell-bent on destruction.
Dark fantasy stories rarely culminate in wholly happy endings. Innocent lives are lost just as frequently as evil ones, and people must often sacrifice all they hold dear to achieve their ends. The choices the characters must make may have no righteous answer—only the lesser of two evils.
