Product overview
Centered on the mud-brick frontier settlement of Thornwall, the module features 8 detailed NPCs, a living job board, a rival adventuring crew, and three competing factions. It contains 30 fully keyed hexes across three distinct danger zones, terrain encounter tables, four main quest lines, seasonal weather rules, and two session-sized dungeons: the Iron Tower and the Bone Cult Excavation.
Thornwall Settlement and 30-Hex Frontier Sandbox
The module establishes Thornwall as an active home base, equipped with an interactive job board, eight fully detailed NPCs, and an ambitious rival crew. Surrounding the town are 30 keyed hexes divided across three environmental zones, providing 10 to 15 sessions of player-driven exploration.
Factions, Dungeons, and System Adaptability
Three competing factions drive the narrative forward without forced plots. The book includes two complete dungeons—the Iron Tower and the Bone Cult Excavation—along with rumor charts, weather systems, search tables, and GM exploration turn references that adapt to Shadowdark, OSR, 5e, or Pathfinder 2e.
Ideas for your table
