The World-Furnace is dying. Hearthrim has decades — maybe less.
Hearthrim is a continent heated from below. For 331 years, the World-Furnace — an ancient engine buried at the planet's core — has kept civilization alive. Heat flows through a network of veins beneath the earth, reaching every city, every town, every hearth. The Covenant manages the flow. The Shivercourt fights to redistribute it. Everyone else tries to survive.
Hearthrim: A D&D 5e Campaign Setting is a complete sourcebook for running campaigns in a world where warmth is currency, cold is death, and the infrastructure keeping civilization alive is slowly failing.
The book includes:
- A fully detailed continent with 6 distinct regions, dozens of named locations, and the great city of Zahren
- Deep political factions with competing agendas — not villains, just people making impossible choices
- New subclasses, backgrounds, and magic items built around heat, cold, and the Furnace
- A complete one-shot adventure to introduce your table to Hearthrim
