As far as the den goes, it's comfortably-appointed and cozy. In addition to the sculpture soon to serve as the rest for Byleth's familiar eagle, the wall above the couch where Musse is currently seated is mostly occupied by a painting, of two eagles at dawn. A brass plate embedded in the frame identifies the work as "The Future".

Meanwhile, Edelgard's eyebrows rise in surprise. "Oh. I didn't know you and Robin were already acquainted." She confesses. "Well! Then things really did work out nicely." But then they're joined by Byleth, and Edelgard turns to greet her warmly, stepping up to the other woman as she places the bow.

"Not to worry. Yes, this is Musse. Actually, it's Mildine Juzalith de Cayenne, but she would prefer to be known by Musse." Edelgard replies lightly shooting a smile in Musse's direction, before leaning in and pressing her lips to Byleth's cheek in greeting. "Hello, darling." She steps back. "I'm just going to get our guest some refreshments, and Robin should be here shortly. I'll just be a moment,"

She slides past Byleth with another fond smile, and out of the room.
