The Court's Heart reminded me a lot of what I have read about Central Park in New York. At one point there might have been grass, but that specific vegetation doesn’t do well with the magic rich environment of the Astral plane, an odd occurrence considering how durable grass was in the Material plane. If it did, I would imagine that most of the Feywilds would be covered in it. It was once said that the Fey used to be barefoot all the time, but that changed over time due to many reasons. The Elders and the older Archfey still retain that social aspect. Seven of them were barefoot while four weren’t. Most Fey, beyond the soldiers and guards, still wore extravagant, yet simple, clothing. The designs lent themselves to loose silk clothing bound by simple leathers or jewelry. Fey clothing tended to be more revealing, so it would be interesting to see how Luna and Daphne react to that.
