Katara sucked in her breath as the room changed to become an exotic landscape. Of everything she had expected, she certainly hadn't expected this. She turned around again, standing in place, and took in all of it. "I couldn't even imagine...how can this possibly exist?" she asked in wonderment. She looked up at the moons, a little dumbstruck. "Aang. This is..." she closed her eyes and concentrated. The landscape changed again, to one mimicking the land of the Southern Water Tribe. She opened her eyes again, her breath frosting as she said, "Unbelievable."
