Following a quick exchange of blows the Forteller pursues the Darkside in the corridor of darkness. He reappears later when the player mastered the power of the Keyblade with the help of Chirishii and a Moogle to explain the player's mission: to defeat the Heartless and collect the light. Before leaving again the Forteller also warns the player of those who hoard the light for their own greed, seekers of darkness disguised as guardians of light.
