Tears of Belphegor is a cinematic-style scenario designed for Wretched Époque during the dark times of the Paris Commune. The Player Characters should be part of the Parisian street scum: "Communards", thieves or murderers, condemned to death by firing squad for betraying their country.
In fact, they fought for a cause they felt was fair, and history will prove them right eventually. But that's not the point here... A group of four or five low-life scoundrel characters would be ideal for this short scenario, playable in one session of 6 to 7 hours.
