|"What manner of faerie are you?"
The title of this article is conjectural. Although it is based on canonical information, the actual name is unknown and may be changed when new information is released.
This lake is located somewhere in the Night Court.
Rhysand goes to Court of Nightmares with Feyre Archeron, Morrigan, Cassian and Azriel to steal the Veritas orb from Keir, the Court Steward and Mor's father. They plan a diversion so that Az can steal the orb.
Rhys sits on his throne and sits Feyre on his lap and then they begin to touch each other to keep everyone's attention on them. After Az steals the orb without a hitch they all go back to Velaris but Rhys and Feyre make a stop at this lake to talk about what happened. There they have a little discussion in which Feyre expresses to Rhysand some of her deepest thoughts about him but which actually express what she feels about herself, but he is very affected by them and avoids her for days.
