Sword of Ecthelion, Gatekeepers hidden city of Gondolin. He was killed during the storming of Gondolin in a fight with the Balrog. This is the only sword with a curved blade belonging to the High Elves Noldor.
The inscription on the blade, in Sindarin - is the battle cry of the Edain (people who fighting on the side of the Elves) and roughly translated means "Shine the Light! Run Night!" And I added another phrase: "Revenge is coming."
Just want to say that Tolkien did not say whether there are any sword of Ecthilion inscription, this is my fantasy ...
