The story is set in a dying world. The society resembles the roman one. The Avatars have unimaginable power due to their knowledge of magical crystals and all the others are either servant-slaves or barbarians to be destroyed. When armies out of a parallel univers come to destroy everything it becomes aparent that Evil and Good depend on points of view and definitions. I especially like this book because Gemmell gave it a nice touch by writing down tales of a people that lives long after the events in the book thus showing how legends come into being and of how little consequence the Now will be in a few hundred years.
