These playing cards are tailored to assist in any solo Role-Playing Game (RPG), but they're particularly good with Caught in the Rain, our solo mystery TTRPG.
It also functions as a normal deck of playing cards, including two jokers.
Each card has:
4 random Non-Player Character (NPC) names
2 six-sided die results
An array of words to spark your imagination
An object to inspire thought
