Ardamel Luewyn (musical riddles) From the house of Dwin'aear (walks in water)
Arda is "Earth" in elvish, and Mel is their given name as a child. since elves give themselves a name, and theyre an absolute magic nerd, I think it would be cute if they were very well-versed in the origins of existence and magic I.E. THE PLANES OF EXISTENCE!!!! esp since Tritons came originally from The Plane of Water and have a huge connection to the element, I think they would find it rly fascinating. And Arda is part of the word for Plane in elvish
sorry for the straight up discord quote
