High king he was to those in exile,
at least he was for a while.
A rescuer of kin - an epic feat
was slain in combat by a Balrog's heat.
Fingon
Fingon was High King of the Noldor in Beleriand after the death of Fingolfin. He rescued Maedhros, his half-brother from the towers of Thangorodrim, and was slain by Gothmog, Lord of the Balrogs, in the Nirnaeth Arnoediad. (Source: The Silmarillion)
