Sky ov Crimson Flame is a 0-level adventure for Dungeon Crawl Classics RPG:

Transcribed from the tattered pages of Sir Hooticus’ tome comes a new tale of adventure sorcery and death! Our story unfolds with the sudden disappearance of the raven-haired beauty Belesa and soon turns to hysteria as others vanish from the small farming village of Reed. One by one friends loved ones and finally the children scream out in the dark of the night and are lost…

Now as the Horned Moon rises a thunderous sound ripples across the night sky and in its wake a falling Crimson Star ignites in the East! The village elders suspect the kidnapped have been taken to an ancient and vile Keep that lies hidden within the dreaded Eastern Forest for they alone remember the old tales of screaming witch-lights that blazed and dance across the sky in times of yore!

Even now strange ululations cry out as fleeting shadows ride the wind. Who among you will brave the bowels of that foul Keep where unspeakable horrors must surely await in an attempt to save those that have been taken?
