The Celestial Squad in Legends of Spirits

You show the letter to Lunaria. She smiles and then gestures you to come in. Once you step into the house you look around in amazement. In front of you is an elegant staircase. To your left is a room that looks like a kitchen. To your right is a glass door, but you can't see trough it.
"Well I'm not the only member of the Celestial Squad," Lunaria said. "The other members came up with a game. In order to learn about the other six members you have to find them. It's like a game of Hide and Seek. So do you want to go to the kitchen or the Training Room?"
