"In the twilight shadows, there he will stand... The One to end Lionblood's reign..." In the forest, the Tigerblood tribe is being annihilated; members are being executed and the trust between Tigerblood and Lionblood is torn. Young members Kaja and Yaffe can only watch the horrible sights. Everyone is engulfed in fear, until the wise Jaagup the Elder tells them all in his final moments that the son of an old esteemed member of Tigerblood shall come to them in their time of need. But when a baffling outsider arrives by the name of Cerberus, the spirit of Jaagup the Elder tells Yaffe he is the One. But Cerberus holds sinister secrets within himself; secrets that could threaten Tigerblood rather than save.
