From back cover
This introduction to the game includes pre-generated characters, a quick summary of the rules, and a full adventure for a GM and 3-6 players. You don't need the 13th Age rulebook to play.
The town of Harrowdale holds a treasure. An army of trolls wants that treasure. You must hold the town until the Imperial dragon cavalry arrives.
You're outnumbered and your forces are outmatched - and to cap it all off, they've got a secret weapon set to bring doom down upon you.
Relying on the old ways - on nothing but a strong sword and a lucky blow - won’t help you now.
Time to make your own luck.
