empress of the aether, the

It is said that beyond the Ice Mountains, beyond the Crystal City, lives the Empress of the Ethereals in a dazzling palace. They say she is so beautiful that no one can look at her without losing their mind. Only the boldest attempt to reach her.
But Bipa doesn't believe in fairy tales. She is not interested in anything beyond the caves where her people live. On the other hand, her friend Aer, the foreigner's son, seems to be drifting further and further from reality, letting himself be absorbed by the glow of the blue star... where they say the Empress of the Ethereals lives. Why does he want to leave if outside there is only ice and, apparently, the only thing one finds is death?
When Aer disappears heading for the Empress's Palace, Bipa is forced to go after him to bring him home. She carries with her the Opal lent to her by Maga, the tribe's shaman, a pendant that will protect her from the cold and restore her strength. In addition, Nevado, a silent snow golem, will soon join her expedition to help her face the dangers. During her intense search for Aer, Bipa will affirm her own identity, the only weapon she possesses against the denial of nature, which only leads to death.
