Oi..the elf is Gil-galad.
Gil-galad was the last High King of the Noldor in Middle-earth
He died during the first ring war by the hands of Sauron himself
A record left by Isildur in Minas Tirith implies that Sauron himself slew Gil-galad, with the heat of his bare hands.
He was the wearer of Vilya( The ring of air) , one of the three elven-rings, ( after he died Elrond got the ring)
I love it so much.
