What do Gwyn and Emerie do when they learn Nesta lives in a magic house?

Gwyn notices all the food, and she wonders if Nesta prepared it all. Emerie says that the House will get you anything you want if you say it out loud. Then they start making requests of the House. They take baths fully clothed in a bathtub filled only with bubbles. They ask for silent fireworks. A miniature pegasus nibbles on grass in a corner. There is a cake taller than Cassian with 1,000 candles.
