Campaign Setting Guide for Perils of Portal Lake

Bring Your Party Into the Mouse World—And Back Again

The Mice of Legend Campaign Guide is the gateway to Portal Lake, a mouse-sized fantasy world designed specifically for Shadowdark RPG.

Unlike most mouse-themed settings, Portal Lake is built around a complete round-trip campaign. Characters begin in their own world before being transformed into mice and drawn into a realm where predators rule the skies, rivers become deadly obstacles, and survival often depends on wit rather than strength.

Whether exploring forgotten ruins, negotiating with rival factions, uncovering ancient mysteries, or simply trying to survive another day in the wilderness, adventurers quickly discover that life looks very different when you stand only inches tall.

A Fantasy World from a Mouse’s Perspective

Portal Lake is not a land of anthropomorphic animal kingdoms. Cats are predators. Owls hunt from the darkness. A simple farm can become an unexplored wilderness. Every journey carries risk when the world around you is suddenly much larger than before.

Designed for fast play, dangerous exploration, and meaningful choices, the Campaign Guide provides everything needed to begin adventures in the world of Mice of Legend.

The Foundation of the Campaign

Inside you’ll find new ancestries, classes, spells, monsters, magic items, setting lore, gods, factions, wilderness regions, and tools for running mouse-scale adventures.

Whether you’re preparing to run the full Perils of Portal Lake campaign or creating adventures of your own, the Campaign Guide provides the foundation for everything that follows.
