E.N. Critters Volume 4: Along the Banks of the River Vaal
This open gaming content sourcebook presents more than two dozen original creatures that inhabit riverbanks and other freshwater environments, from temperate regions to warmer climates. The River Vaal provides a broad setting framework, with descriptions spanning streams, marshes, lakes, waterfalls, forests, and deltas. Each creature includes detailed ecology and background, a Suggested Knowledge table, a Rules & Game Balance section, full-colour artwork, and a counter. The setting information remains flexible so the creatures can be adapted to other campaigns and freshwater locations.
