During the era of the Great Migration, the Siluit people set sail on a huge fleet across the ocean. Hundreds of people are leaving their devastated native land in search of a better life on a mysterious continent buried in dense forests. The young prince Sibor believes that in order to prevent a new catastrophe, his people must become more merciful to the world around them. But his father, a cruel king who prefers to solve problems by force, rejects these ideas and despises his son, considering him an unworthy heir. Fate brings a young Raidan woman, a representative of a hostile people, to the ship. Everyone on board wants her dead, except Sibor. Now the prince has to make a difficult choice: follow his ideals of mercy or take a risk and take a different path... "Sibor the Merciful" is included in the collection of prequel stories of the fantasy saga "Whispers of the Gods."
