13th Age

13th Age is a fantasy tabletop roleplaying game that blends d20 mechanics with narrative-focused gameplay. It emphasizes collaborative worldbuilding, character-driven stories, and tactical combat.

Theme and Setting

The game distinguishes itself through its Icons, abstract range bands, and the Escalation Die, which promotes dynamic and cinematic encounters. 13th Age aims to provide a streamlined and flavorful experience for players seeking heroic fantasy adventures.

How Play Feels

13th Age is set in a high-fantasy world defined by the influence of thirteen powerful Icons. These Icons are not deities but rather individuals or factions wielding significant control over various aspects of the world, such as the Archmage, the Emperor, the Crusader, the Lich King, and the Great Gold Wyrm.

What Makes It Distinct

The world's details are intentionally left somewhat vague, encouraging GMs and players to collaboratively shape the setting to fit their campaign's needs. This approach allows for a customized and emergent world, where player choices and Icon relationships directly impact the unfolding narrative.

Where It May Not Fit

You want a very light rules load You want the system to stay almost invisible at the table.
