Húrin

Húrin is born into the House of Hador, one of the three houses of the Edain, and is brother to Huor and husband of Morwen; he is father to Túrin and Nienor. As a lord of Dor-lómin he becomes renowned among Men. He fights in the great wars of the First Age (including engagements around the time of Dagor Bragollach and the battles against Morgoth), and at a decisive moment he and his brother are aided by the Eagles and by Ulmo. Húrin is captured by Morgoth in the wake of these conflicts and is bound upon a high seat at Angband for 28 years, where he endures torment and interrogation but refuses to reveal the hidden city of Gondolin. After his release he returns to Beleriand, wanders with outlaws, seeks vengeance, and his anguished cry (after release) contributes to the disclosure of Gondolin’s location; the cascade of tragedies affecting his children and kin culminates in his suicide following the deaths of his family.

In battle Húrin is mainly described by his deeds and martial presence (riding the war-horse Arroch in narrative accounts). After his 28 years of captivity he is explicitly described as having grown grim to look upon: "his hair and beard were white and long, but there was a fell light in his eyes. He walked unbowed, and yet carried a great black staff; but he was girt with a sword." Earlier life-portrayals emphasize a formidable warrior's bearing rather than specific physiognomic detail.

Húrin is characterized by exceptional martial skill and leadership — the sources call him the greatest warrior among the Edain and among Men of his time, able to rout Orcs and hold stands that enable others to escape. He demonstrates extraordinary endurance of will: while bound in Angband he withstands Morgoth's torment and refuses to betray Gondolin's location. After his release he displays fierce stubbornness, roaming with outlaws and inciting revolt in pursuit of vengeance; his psychological collapse and cry after release become pivotal, unintentionally aiding Morgoth's designs. He has no supernatural powers in the texts—his influence is through military prowess, reputation, and moral/psychological force. (Sources: Wikipedia; Valar Guild; critical summaries)
