Is The Prophet of Yonwood a prequel?

Could you clarify whether "The Prophet of Yonwood" is intended as a prequel to an existing work or series? Are the events within its narrative meant to precede those of another story, setting the stage for future events or characters? Alternatively, does it stand as a standalone narrative, unconnected to any predecessor in terms of plot or timeline? I'm eager to understand if readers should anticipate familiarity with a previous story to fully appreciate "The Prophet of Yonwood".
