From the introduction:
Gates of Gehenna [is a] Cloak & Dagger-style role-playing game about personal ambition, religious conflict and survival in an uncaring world.
...
Gates of Gehenna is [set] in a twisted fantasy world close to the end times during a development stage not unlike our own late renaissance, when great religious wars are fought within a crumbling empire of old.
Everywhere the tell-tale signs can be found, crops go bad animals are infected with strange diseases, while beasts and worse have overrun the countryside, doomsayers plague cities as do widespread illness and war, as political and religious motives cross towards dangerous holy wars between the remnants of once-great empires amidst the ruins of ages.
Above all a strange cult, the Eye and Star, have proclaimed the dawn of the end times and many believe the opening of the Gates may be near, the time when the world shall end, and all be lost to the unspeakable void.
