The Princess has chosen not to invite any of the good-allured knights. On this night, the only two people in the Dream Citadel are Luka and the Protector.

The Protector can be found on the roof, stargazing and listening to the sounds of the waterfalls around the tower. Luka will arrive near the base and have to climb, but at least he'll be surrounded by the sounds of the waterfalls.
