Travel between Almanac: The Dragon Road and Almanac: The Crystal Peaks and craft a trip that no one has ever taken. The Treacherous Trails pack is a unique deck of encounter cards that will bridge both books of Almanac: The Dragon Road, and The Crystal Peaks so you can play them together!

This was originally available through Kickstarter, but was later sold separately. This expansion includes:

15 Treacherous Encounter cards
12 Contract cards
10 Encounter cards
4 Advanced Starting Caravan cards
1 Trail Guide card
