Has your party run off in an unplanned direction? Turned an off-hand remark about a random event into the central point of the session? Or are you just looking for inspiration as you plan out your campaign? Sidequest Decks will give you a wealth of adventure ideas. Skim the first couple of sentences of a few, pick one that's close to what you need and improvise the quest outline to fit!
54 adventure outlines focused on a magic school. 1 Card gives an overall floorplan for a 2 story mage school.
One side is the main encounter map; the other is a mini-adventure outline: background GM info, 2 ways to start the adventure, several encounter ideas, and a follow-up adventure idea or two.
