In the universe of Game of Thrones, Valyrian steel swords are not only powerful weapons but also symbols of lineage, loyalties, and conflicts.
Among them, Oathkeeper and Blackfyre stand out for their history, legendary design, and their role in the events that shaped the Seven Kingdoms.
This article explores their origin, characteristics, purpose, and who wielded them.

Oathkeeper: The Sword of Loyalty
Origin and Valyrian Forging
Oathkeeper is a sword forged from Ice, the ancestral greatsword of House Stark.
After Eddard Stark's execution, Tywin Lannister orders Ice to be melted down and two new Valyrian steel swords to be forged.
One of them is Oathkeeper, with an ornamented hilt and lighter blade, designed for agile combat.
Wielders and Legacy
The sword was given by Jaime Lannister to Brienne of Tarth as a symbol of trust.
Despite its Lannister origin, Brienne turns it into an emblem of loyalty to the Starks and her oath to protect Ned's daughters.
Oathkeeper not only represents a powerful weapon but also the conflict between honor, redemption, and duty.
Brienne wields it steadfastly, defending the innocent and fulfilling promises, which transforms the meaning of the sword.
From a weapon forged in times of betrayal, it becomes an emblem of justice and protection.
Narrative Function
Oathkeeper acts as a redemptive symbol for Jaime and Brienne.
The act of gifting it implies a profound change in Jaime, and for Brienne, it is the reaffirmation of her worth and purpose.
It is a sword that protects, not one that seeks revenge.

Blackfyre: The Standard of a Rebellion
Origin and Targaryen Heritage
Blackfyre was forged in Valyria and belonged to Aegon the Conqueror, founder of the Targaryen dynasty in Westeros.
Unlike his other sword, Dark Sister, Blackfyre was a straight Valyrian steel greatsword, with a black hilt and inlaid rubies.
It was a symbol of legitimacy for generations of Targaryen kings.
From Royal Emblem to Rebel Standard
The history of Blackfyre takes a turn when Aegon IV the Unworthy gives it to his bastard son Daemon, legitimized under the Blackfyre surname.
This turns the weapon into the standard of House Blackfyre, who led various rebellions against the legitimate Targaryen branch.
From then on, the sword ceased to be a symbol of unity and came to embody division and dynastic conflict.
Wielders and Destiny
Daemon Blackfyre was the first great wielder of the sword after Aegon.
He fought with it in the First Blackfyre Rebellion, where he died at the Battle of the Redgrass Field.
From then on, Blackfyre passed through the hands of other rebel descendants, but its final fate is uncertain.
In the time of the books, the sword is missing, leading to speculation about its whereabouts.

Two Swords, Same Steel, Two Opposite Paths
While Oathkeeper represents transformation and redeemed honor, Blackfyre is a reflection of ambition and family division.
Both share an ancestral origin, Valyrian steel, but their narrative journeys oppose each other: one protects promises, the other provokes civil wars.
They are two faces of power in Westeros, reminding us that a sword not only kills but also conveys legacy.
