Argon was the fourth child and the youngest son of Fingolfin, the High King of the Ñoldor in Beleriand. He was one of the mighty Prince of the Ñoldor in Tirion, Valinor. Furthermore, Argon grew up in Valinor, until later, the Ñoldor went into exile for Middle-earth where he journeyed with his father Fingolfin and his siblings.
Biography
Argon was therefore the last child and the third son of Fingolfin and Anairë who was also of the Ñoldor. Argon was the younger brother of Fingon, Turgon, and Aredhel his elder sister. He was most likely born in Tirion during the Years of the Trees. He was described to be the tallest of his brothers and most impetuous. He followed his father through Helcaraxë and set foot on Middle-earth during the First Age. During the Battle of the Lammoth, Argon hewed a path through the foes and killed the Orc captain, before he himself was slain.
Argon was less than 1381 years old when he was killed - a young age for an Elf. His death was the first signs of the Doom of Mandos.
Etymology
Arakáno thus never received a true Sindarin name, but Argon was later devised for him in the records. It is recorded that this later became a popular name under the Eldar. His Quenya name was Arakáno ("High Commander"), named so partially for his character.

Other versions of the legendarium
Argon does not appear in the published The Silmarillion at all, as he only came to light in very late writings by Tolkien. His death has been changed twice; Tolkien intended for Argon to die during the Kinslaying at Alqualondë, but then later changed it to Argon perishing while crossing the Helcaraxë.
