Virgilio's Untold Tales is the game's "Master's Guide" and "Monster Manual", and it contains adventures, perils, game hooks, special equipment, a whole campaign, and the bestiary, together with a deeper description of the Inferno as a "sandbox", to be used after the end of the campaign.

In Inferno, players are Lost Ones, in their journey toward the Last Gate, the only exit from Hell. They can come from any world or plane, and of course also from our Earth, but when entering Hell they will appear as a unique character, primarily forged by their virtues and sins in an otherworldly look. They are alive and they could stay alive during the whole voyage, like Dante was in his, but the Inferno itself, with its demons, damned souls, and perils will try to catch them and enslave them forever.

The main challenge of the Lost Ones is not to face and defeat damned souls and monsters, but to keep their path and their Hope during the voyage!

In this volume the game master can find all he needs to torment the players during their voyage through the circles of Hell, including creatures, monsters, hooks for adventures, and encounters to make this game experience special, an endless emotion for all the players who dare to try it. The compendium of the evil creatures of Hell includes the nine mythical Guardians of the underworld.
