"You are an oracle, a greenseer, and a fraud. You know nothing you do will affect whether a season is bountiful or not, whether nature will be kind to your clan or not. 

But you must convince your chieftain that your rituals are worthy, that their offerings, with your guidance, can decide their fates. If not, you may be exiled or worse."

“Superstition” is a ritual-creating solo journaling rpg with light game elements a little similar to blackjack (no knowledge of that game required). Played with a normal 52-card deck.
