Story Hook

A cursed mining town, a spreading eldritch corruption, and a crimson moon hanging overhead — descend into the depths of Red Hollow before the Obsidian Heart consumes everything.

Adventure Overview

The town of Red Hollow is dying. Once a thriving mining settlement, it now sits beneath the glow of an unnatural crimson moon. People vanish during the night. Strange whispers echo from the abandoned Berylcrown Mine. Crops rot. Animals mutate. And the townsfolk speak in fearful hushed tones of something awakening below the earth. Players are drawn into a layered horror adventure filled with mystery, corruption, and escalating danger. Beginning with investigations inside the cursed town, the campaign slowly descends into claustrophobic mine tunnels where eldritch horrors, ancient rituals, and reality-warping corruption await. This adventure combines: Narrative-driven roleplay Exploration and environmental storytelling Survival tension and psychological horror Challenging combat encounters Moral dilemmas with meaningful consequences Player-driven choices that shape the ending Players will encounter corrupted miners, spectral horrors, twisted beasts, dangerous puzzles, and the terrifying influence of the Obsidian Heart — an ancient entity pulsing beneath the mine.

Reviews

What Dungeon Masters say.

Best campaign I have run in five years. The villain alone was worth the price.

Maris T.

My party hated me. In the best way. The pacing is unreal.

Owen K.

Stunning prose and cinematic moments. I needed one extra session to land the ending.

Aiyana D.

I have never had so little prep for so much payoff. Buy it.
