From publisher (Inkwell Ideas) blurb:
Need adventure ideas including ways to get the adventure started, several possible encounters along the way, and a couple of follow-up possibilities? Use our SideQuest Decks!
Each card helps you build a dynamic adventure!
Draw a card for an adventure outline. The outline includes backstory, ways to get the PCs involved, encounter possibilities, and follow-up ideas. The other side of the card is the most important map for that adventure. Need more maps? Borrow one from another card.
