This session is for GMs, game designers, and writers (any genre). Your adventurers make journeys on rivers, struggle to cross them, and seek them to sustain life (also maybe for a badly needed bath). See how your story can be enhanced by richly depicting one of the distinctive types of river channels, considering natural patterns of sandbars and islands, and incorporating tricks that currents and streambed erosion can play on unwary travelers. How does a river’s look and behavior change as you travel downstream? What interesting, game-changing terrain elements inhabit river floodplains? How are floods different from one river to another? Make each river scene memorable, with the help of a GM/geologist.
