This book is the beginning of a story about the invincible desire for life, friendship and love. You will be immersed in the world of Aira - the “Heart of the Worlds” - from which the birth of all other corners of the Universe began. Here the Firstborn rule with the hands of their faithful Guardians and the confidants of the imperial court of the mighty Sentorius weave treacherous intrigues. Life in this beautiful world could have gone on as usual if, on the first morning of spring 1121, the Guardian, chosen to serve the judge of the world, had not come into it. All the sages predict the death of Aira, expecting to see an unshakable warrior brought up in the best traditions of the Academy and whose goal is to return the world to emptiness as the Guardian. Meanwhile, a young girl, deprived of any memories of the past and, perhaps, that is why she is so passionately in love with life and Aira herself, has become the true Guardian. The first book in the trilogy will tell about Cepheus accepting her role in the world of Aira and about the adventures that the Guardian met at the beginning of her journey along with her true friends and mentors.
