Multi-System TTRPG Campaign Generator
SessionRoll is a deterministic campaign generator supporting multiple tabletop roleplaying game systems including Dungeons & Dragons 5e, Pathfinder 2e, Call of Cthulhu, Shadowrun, Vampire: The Masquerade, and System Agnostic campaigns. Select your game system and setting, then enter any seed to generate a complete, thematically-appropriate campaign with villains, factions, NPCs, plot hooks, and world-building elements tailored to your chosen world.
Each game system includes multiple official settings: D&D offers Forgotten Realms, Eberron, Ravenloft, Greyhawk, Dragonlance, Dark Sun, and Planescape. Pathfinder features Golarion, Irrisen, and more. The same seed always produces the same campaign within your selected system and setting.
Whether you're a Dungeon Master running Forgotten Realms, a Pathfinder GM exploring Golarion, or a Keeper investigating 1920s Arkham, SessionRoll provides system-specific campaign content with zero setup required. All generation happens in your browser, with no account needed and no data stored on servers.

Frequently Asked Questions
What TTRPG systems does SessionRoll support?
SessionRoll supports Dungeons & Dragons 5e (Forgotten Realms, Eberron, Ravenloft, Greyhawk, Dragonlance, Dark Sun, Planescape), Pathfinder 2e (Golarion, Irrisen), Call of Cthulhu (1920s New England, Modern Day), Shadowrun 6e (Seattle, Neo-Tokyo), Vampire: The Masquerade V5 (Chicago, Los Angeles), and System Agnostic (High Fantasy, Dark Fantasy, Swords & Sorcery, Political Intrigue, Sea-Faring, Wilderness Survival).
What is the System Agnostic option?
The System Agnostic option generates campaigns that work with any TTRPG system. Choose from thematic settings like High Fantasy, Dark Fantasy, Swords & Sorcery, Political Intrigue, Sea-Faring Adventure, or Wilderness Survival. These campaigns focus on universal narrative elements rather than system-specific mechanics.
Is SessionRoll free to use?
Yes! SessionRoll is completely free with no account required. All campaign generation happens in your browser with no server-side processing or data storage.
How does the seed system work?
The seed is used as a deterministic random number generator input. The same seed with the same system and setting always produces the same campaign, allowing you to share campaigns via URL or return to previous campaign ideas. Change the system or setting, and you'll get a different campaign for the same seed.
Can I edit generated campaigns?
Absolutely! Every element of a generated campaign can be edited. You can also reroll specific sections (villain, factions, NPCs, etc.) while keeping the rest of your campaign intact.
