Cairn 2e Warden's Guide
A GM toolkit for running low-fantasy, OSR-style adventures in the Vald setting or any similar world. It collects tools, tables, and procedures for generating locations, encounters, factions, and plot seeds that fit into a gritty exploration-focused campaign. Chapters provide step-by-step guidance for creating scenes and adventures, plus advice on pacing, stakes, and improvisation. Random tables and modular prompts support quick preparation and on-the-fly content creation, while design notes help tailor challenges and atmosphere to player choices.
