After the volcanic eruption, the Sun disappeared behind a cloud of ash and a harsh, long winter reigned all around. Gilas, having never found his missing sister, sails to Keftiu to find and save his friend Pyrrha. But the Ravens, led by the power-hungry Telamon, also rush to the island. Telamon knows what Hylas does not know: when the volcano woke up, Pyrrha managed to steal the Koronos dagger, which is mentioned in the prophecy. Together with the little lioness Robber and a falcon named Echo, Hylas and Pyrrha will once again enter into a dangerous confrontation with the Ravens, and the fate of the entire island will depend on its outcome.
