Infærnum is a rules-light RPG centered on apocalyptic themes. Everything begins with a single event — a prophecy that triggers the end of times. Over the course of seven days (in the narrative), players must overcome countless challenges and reach the promised land before the end of all things, confronting the Four Horsemen and other Revelation-inspired tropes.

Or not.

In this highly original game, you define your own vision of the Apocalypse. Infærnum can be played as a standalone experience or seamlessly adapted to any campaign or system. You can even layer it on top of your current RPG to explore how your world faces its final days.

It’s both a doomsday device and a toolbox — ready to bring the end of the world to any table.

Frustum – Dæmo Version is a playable glimpse of the upcoming sequel to the award-winning Infærnum: Extreme Role-Playing Game. Built upon Infærnum’s core rules, this module transports you to the remnants of a world long past its end. The apocalypse struck a millennium ago, leaving behind lifeless bodies that do not decay, until they’re claimed by wandering immortal souls.

You are one of these immortals: a memoryless spark inhabiting the dead to uncover fragments of your world’s forgotten past. Explore cradles of power, claim new vessels, face the Fallen, and unearth what remains of humanity across a realm of decay and memory.

Played without a gamemaster, Frustum – Dæmo Version turns every ruin into a mystery. Each session unfolds through questions, dice rolls, and imagination, revealing both the beauty and horror of the body you now inhabit. When rot claims your vessel, you awaken anew, changed, yet burdened by all you’ve learned: from your brightest virtues to your most shameful sins.

This preview directly connects to Infærnum, serving as both a continuation and a glimpse of what’s to come: a standalone experience set in a world where immortality itself festers into damnation.
