who is nelyafinwe?

Nelyafinwe is a character from J.R.R. Tolkien's legendarium. He is also known as Fingolfin, one of the High Kings of the Noldor Elves in Middle-earth. He was the second son of Finwe and half-brother to Feanor. Fingolfin was a renowned warrior and leader, known for his bravery and valor in battle against the forces of Morgoth.

no you are wrong.

I apologize for the error. Nelyafinwe is actually another name for Maedhros, the eldest son of Feanor in J.R.R. Tolkien's legendarium. Maedhros was one of the leaders of the Noldor Elves during their exile from Valinor. Thank you for pointing that out.
