Storycaster: Fantasy Realms

From BoardGameGeek:

Storycaster is a game designed to help people run a Session Zero for their TTRPG campaigns. By using a combination of illustrated prompts and motivating questions, players will quickly find themselves building worlds, creating characters, items, monsters, adventures, and more. It has a single player mode, but it is best played collaboratively with up to 8 friends during a Session Zero. Compatible with any TTRPG. -description from the publisher
