Best ForGroups who want mouse-scale sandbox adventures where clever plans and careful supplies matter more than fighting. The rules support exploring dangerous ruins and returning treasure to a safe settlement.Groups who want treasure-driven dungeon expeditions and open wilderness campaigns with fragile starting characters.
HighlightsCondition cards occupy inventory slots, forcing a choice between carrying supplies and enduring setbacks. Spell tablets trade greater power for faster depletion and dangerous miscasts. Faction goals advance between sessions, letting the world change beyond the mice’s immediate adventures.Treasure recovered from adventures provides most experience points, rewarding successful exploration over fighting alone. Reaction and optional morale rolls let encounters lead to negotiation or flight instead of automatic combat. Stronghold construction and taxation let accumulated wealth support a growing domain.
ConsiderationsDamage beyond Hit Protection reduces Strength and can incapacitate a mouse after a single failed save. Depleted spell tablets require specific fictional tasks to recharge. Advancement improves attributes and endurance rather than offering classes or extensive ability choices.Characters die at zero hit points, and failed poison saves are usually fatal. Demihuman characters combine ancestry with class and have lower level limits than human classes. Declared spells are lost if the caster is hit or fails a saving throw before acting.
