The Worldwide Adventure Generator (WAG) is a zine of genre- and system-agnostic procedures for improvising hexcrawl adventures on the fly. This page brings that loop online, tuned for Tiny d10 and wired to the Fantasy Monsters bestiary.
It runs the hex loop one step at a time: weather, features, signs, an encounter check, and—when something stirs—a full encounter drawn from the monsters (filtered to the terrain and its ecology), wrapped in tension, discovery, and a turning faction clock.
Set your terrain and campaign intensity, then Enter hex. See also the standalone Random Monster roller.
