This book will be something akin to a historian writing from their perspective about events which proceeded the rise and then facilitated the fall of the Great Empire of Utopos.

Some pre book explanation (the shown map should help visualize it better):

The region described in this book is called Homia. It is further subdivided into 4 sub regions. Fayene in the west including the desert and the surrounding coast, the Eastern peninsula in the center of the map including the entirety of Vortexus and Uchistan, the Pyro islands in the north east and the Utopo islands in the south east. The main focus of this book will be probably on the Eastern Peninsula.

Even if the book is called the rise and fall of Utopos, Utopos doesn't become a major player in the book until later. In the beginning of the book the author will just write about the history of the Eastern Peninsula, their homeland.
