Campaign Setting Guide: Perils of Portal Lake

This campaign guide introduces a fantasy setting where player characters are transformed into mice and must navigate forests, cities, dungeons, mines, and waterways. The campaign begins when a sacred relic vanishes from the human realm and is hidden in the mouse world. It provides lore, locations, NPCs, side quests, maps, monsters, spells, and magic items for a series of connected adventures. Conversion tables support AD&D and OSRIC characters, with guidance for adapting the campaign to 5e, OSR, Pathfinder, and related systems.
