The Conqueror's dragon, Balerion, more famously known as the Black Dread, was among the five dragons Aenar Targaryen brought to Dragonstone from Old Valyria. He was also among the three dragons of the Targaryen siblings, the other two being, Visenya's Vhagar and Rhaenys' Meraxes. Aegon the First of His Name rode the Black Dread during the Conquest and used his dragonfire to burn countless Westerosi during pivotal events such as the Field of Fire and the Burning of Harrenhal. Balerion's skull features in HBO's House of the Dragon as well as the original series, Game of Thrones.
