Every thirteen years, the alignment of the stars and the conjunction of the spheres heralds the night of the blood moon of Aperta-Mundi. In this frigid darkness the sphere of Selûne is stained crimson, igniting the anger of unholy spirits incarnated in accursed flesh and driving them to swarm in an assault on the helpless villagers wintering near Fort Zvezda in the tundra of Krakozhia. Can you and your companions hold back the seething horde before they strike at the innocent with flame and steel?

Prepare a 6th level character who has made their way to the icy wastes of modern Krakozhia far from the comforts of the cosmopolitan capitol of modern Ortun. As the thick snows fall across the continent of Civorea, and the night sky is stained red, you know the giant eagles of Highspire will not be flying to your rescue. The only thing that stands between the horde and a massacre at Fort Zvezda is you.
