I've got a traditional isekai kind of fantasy, where the main character falls into another world during a stormy night...and promptly hits his head, suffering from amnesia and forgetting everything that happened to him before that point.
Storytellers is a high fantasy novel that utilizes a unique magical system, where instead of casting spells, people tell stories to use their magic. In this world, you could use a story to do anything from carry you across a gulf, plant your fields, or make it rain. The only thing you're not allowed to tell...is a story where people get hurt.
I'm sure no one would go and break that law, though, right?
