[Galorme]

The reason that Elves do not explain their Magics to others is not usually for secrecy, but more for the reason why you don’t explain how you walk or talk, it is innate to you. Its like the Elves of Lórien being puzzled by the question "is it magic", as making rope that unties itself, like making a sword that glows when Orcs are around, is just something they do. There are very few times that elves acknowledge magic, and these are usually in the case of Maia (the Istari) or
Half-Maia (Lúthien).
