Saravara is a vast rainforest kingdom shaped by forgotten civilizations, river clans, foreign rulers, rebellion, invasion, and war. Nineteen-year-old Aren Jala expects an ordinary life until he discovers an ancient crown beneath his family home and awakens the Echo, a power that lets him witness memories left behind by people, relics, rivers, and the land itself. Through these visions, Aren uncovers centuries of hidden history and repeatedly encounters the same symbol: a black hornbill surrounding an empty throne. Behind every fallen kingdom stands a secret organization known as the Archive, which seeks to preserve humanity by trapping every consciousness inside an eternal collective memory. Chosen by the legendary Hornbill Throne, Aren must uncover the truth of Saravara’s past before history is rewritten forever.
