Valyrian Steel and Other Weapons

Valyrian steel was invented in Valyria, and was used to make weapons and various other items of unparalleled quality. Magic and spells play a role in its forging, which makes the steel special and gives it magical characteristics. Though by far the most well-known and common means of making uncommon swords, there are weapons not made of Valyrian steel that share similar properties.

Known Blades

 * Blackfyre, the sword of Aegon I Targaryen. Carried by all Targaryen kings until Aegon IV, who gave it to his bastard Daemon, who rose in rebellion against the Targaryens, taking the sword's name for his house. Recovered by Aegon VI Targaryen.
 * Heartsbane, the ancestral two-handed greatsword of House Tarly.

Possessed by Baelon Targaryen during the War in the Narrows, but later recovered by royal forces. It was refashioned on the orders of Rhaegar I, and gifted to his son Aenar.
