Carried by Aegon the Conqueror when he first left Dragonstone for the Seven Kingdoms , Blackfyre was an ancestral sword of his house that became a symbol of the Targaryen dynasty in Westeros.
Aegon I carried it throughout his reign and used it in many battles, upon his death it was passed on to his heir and successor Aenys. However Aenys gifted it to his younger brother Maegor who was the better warrior and more suited to the blade. Many viewed this as a mistake that legitimized Maegor’s later usurpation of the throne.
The sword continued to be used and carried by the Targaryen kings for generations, in peace and in war. Until 182 AC when Aegon IV gifted Blackfyre to his bastard son Daemon, instead of his more scholarly legitimate heir. Daemon took on the name Blackfyre, after his father’s blade, and formed House Blackfyre. The waters of succession were further muddied when Aegon IV legitimized Daemon Blackfyre on his deathbed. The final result was The Blackfyre Rebellion in 196 AC.
The rebellion proved unsuccessful and Daemon was slain, riddled with arrows from archers under the command of Lord Brynden Rivers, himself another bastard of Aegon IV who stayed loyal to the crown. Daemon Blackfyre’s half brother, Aegor “Bittersteel” Rivers, a bastard who had joined with the rebels took up Blackfyre and fled with it across the Narrow Sea to the Free Cities where the sword was lost to history.
