    Two legendary swords from Game of Thrones

    In the universe of Game of Thrones, Valyrian steel swords are not only powerful weapons but also symbols of lineages, loyalties, and conflicts.

    Among them, Oathkeeper and Blackfyre stand out for their history, legendary design, and their role in the events that marked 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 ornate hilt and a 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 transforms it into an emblem of loyalty to the Starks and her vow to protect Ned's daughters.

     

    Oathkeeper not only represents a powerful weapon but also the conflict between honor, redemption, and duty.

    Brienne wields it firmly, defending the innocent and keeping 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 banner 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 banner

    Blackfyre's story takes a turn when Aegon IV the Unworthy gifts it to his bastard son Daemon, legitimized under the Blackfyre name.

    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 major wielder of the sword after Aegon.

    He fought with it in the First Blackfyre Rebellion, where he died in the Battle of the Redgrass Field.

     

    From then on, Blackfyre passed through the hands of other rebellious descendants, but its ultimate fate is uncertain.

    At the time of the books, the sword is missing, leading to speculation about its whereabouts.

     

    Two swords, same steel, two opposing paths

    While Oathkeeper represents transformation and redeemed honor, Blackfyre reflects ambition and family division.

    Both share an ancestral origin, Valyrian steel, but their narrative paths oppose: one protects promises, the other provokes civil wars.

    They are two sides of power in Westeros, reminding us that a sword not only kills but also conveys a legacy.
