In the summary of Dow,^[2]: 67

The first book begins with rumors of the imminent attack of the Nazeels on human settlements. These rumors travel fast to the court of kings in the capitals of kingdoms and empires, and everyone hears of the impending attack and speculates about the fate of mankind in the next war. However, the Nazeels [...] fail in the attempt because of the union between the Wandering Knights and the men. The book further shows the interactions between the three people who live in Ethera.

Dow summarises this novel thus:^{[2]: 67–68}

The Priest is the moving power of the Nazeels, urging them to attack humans. Nothing stands in the way of the Nazeels, who are taking revenge on the men and the knights who stood in the way of their previous attempts to conquer. These battles cause the destruction of human cities and the slaughter of their inhabitants and their fighters. However, the knights have a different plan that adheres to an ancient prophecy. The prophecy predicts that this desperate war will not be victorious except by the forces of evil, and that the knights must return to their ancient land where a hero will appear who will lead them to victory in the future.

According to Dow,^[2]: 68

Here, the readers are introduced more in-depth to the Black Priest and the Nazeels, among others, and to the essence of the war between the various groups. The Moziro, the dwarfs, and the mermaids get involved in the war as well, and each of these groups has an agenda. The focus of the third book is Micora, the dwarf Island. The book also ends with several battles, all of which result in the defeat of humans, and it seems that there is no hope to confront the forces of the Black Priest who also uses giants, dwarves, the Morizors, the Knights, and traitors among the human race.^[2]

In the assessment of Noura Al Noman,

The story is timeless [...] Readers who were never exposed to fantasy epics like Lord of the Rings will be fascinated by the detailed settings, clothes, and weapons. The combat scenes are described in detail, as if they were being played out on a screen. Furthermore, to create a series of books means the readers will be asking for more, and that is the greatest gift to Arabic literature. There is no single protagonist in the story to place all of our hopes on; there are many characters from the various races. This has resulted in two-dimensional, stereotypical characters, and I personally couldn’t empathize with any of them. But for a young adult who has little to no fantasy to read, I think this is a great series of books.^[3]
