How It Works
SOJEN empowers Game Masters to build rich post-apocalyptic D&D campaign worlds through structured world-building. Create entities for your survivor factions, mutated creatures, ruined locations, and ancient artifacts. Document your campaign's canon—the cataclysmic events, faction politics, and session recaps that shape your wasteland. Organize everything into story arcs to track major narrative threads like rebuilding civilization or uncovering pre-fall secrets. Generate codex documents as player handouts detailing known ruins and factions. With timeline tools, track the years since the fall and advance your world as civilization rebuilds. Connect your Discord server so players can interact with NPC survivors between sessions.
