The 350 pages of the 13th Age Second Edition Heroes’ Handbook include character creation, a chapter on the kin, classes, backgrounds, the combat rules, icon connection rules, and writeups of each of the icons to help players use their connections in fun ways that shape the story. To help people get into the game, the book opens with a 17-page example of play covering campaign planning, character creation, and the first four battles fought by a party of heroes exploring a cemetery overrun by Lich King cultists.
