As you accept Thrainn's invitation to join the Firefly Orchestra, a burst of sparkles erupts from his tiny cane, surrounding you in a shimmering glow. The fireflies swirl around you, creating intricate patterns in the air as they harmonize their twinkling lights with your heartbeat. Thrainn giggles gleefully, leading you towards a majestic toadstool stage at the center of the clearing where a concert is about to begin.
