#99: The Last Hearth | The Warmth Is Not Free A Cozy Horror One-Shot for Fifth Edition

They came in from the blizzard for a warm fire and a bowl of stew. The fire is what is hunting them.

The Last Hearth is a remote mountain inn famed for a warmth that never dies. Your players stagger in from a killing storm, grateful for the light in the window and the good smell of the pot. The innkeeper asks only that they follow three simple rules: stoke the fire before midnight, never open the windows after dark, and if you hear singing from the hearth, do not answer. Before the night is over, every rule will be broken.

By midnight one of the other guests lies frozen solid in his bed, three feet from a burning stove, a smile on his face. The storm outside will not let anyone leave. And the warmth that drew the party in was never shelter at all: it is the prison of a starving spirit, and the walls are getting thin.

A complete, ready-to-run one-shot for fifth edition, built for a single evening and zero prep. Everything you need is on the page. Read-aloud boxes set the mood, skill checks reveal the truth instead of gating it, every fight comes with tactics and a plan for when your table is losing, and contingencies cover the moment the party zigs when you expected a zag. Open the book, skim the act, and play.

As the night deepens the adventure forks. Search the guests' rooms and the innkeeper's hidden ledgers, or descend to the frozen vault beneath the floorboards. Both paths uncover the same terrible truth and both lead to the Heart-Cinder, the keystone that decides how the night ends. Three endings wait there, and none of them is clean. The choice belongs to your table.

At the center of it is the Cinder-Bride: a jilted spirit of cold flame, promised a hearth that would never go cold and left to freeze on the eve of her wedding three hundred years ago. She has fed quietly on the inn's guests ever since, and tonight she is done waiting. The innkeeper is no villain but a jailer worn down by the weight of what she has done - one of the most human antagonists your players will ever be asked to judge.

This is cozy horror at its best: the stew is genuinely good, the company is warm, and the thing behind the walls is ancient and hungry. It sells the comfort of being inside during a storm, then slowly turns it into the dread of realizing the storm is inside too.

What's Inside:

• Over 70 pages, playable start to finish in one 2-3 hour session
• Built for 2-3 players at levels 2-3 - any two of the four included heroes form a viable party
• Four acts and fifteen named scenes, from a cozy welcome to a three-phase finale
• The Ash-Wane dread system - a rising tension meter that escalates the night no matter how cleanly your table plays
• A three-phase boss fight tuned so it never one-shots a hero and never skips its own climax
• Six original creatures with full stat blocks, fifth-edition (SRD 5.1) compatible
• Four ready-made characters with personalities, tactics, and roleplay notes
• Four maps - an inn overview plus three tactical encounter maps
• Six opening hooks and three distinct endings your table chooses for itself
• An aftermath and campaign seeds that turn one night into the start of a story

Perfect For:

- Busy Game Masters who want a finished, quality session without the prep grind

- Small groups and two-player duets after a single-evening scare

- A one-shot for a winter night, a convention slot, or a break between long campaigns

- New Game Masters who want a complete adventure

Every scene names its purpose and mood, every revelation is supported by at least three separate clues so a missed roll never hides the truth, and the encounter math is stress-tested for the worst-case two-player party so no one gets left out in the cold.

Light the fire, bar the shutters, and whatever you do, do not answer the singing. Ready to run tonight.
