Use them as chance encounters or to provide detail for an existing map. The One Page series gives the GM instant access to random tables full of woodland landmarks, strange objects, minor treasures, clever traps, and more! Each One Page product contains twenty unique, system-neutral entries in ready-to-roll format. Each entry can be easily adapted to any fantasy role-playing game.
