Intro. Prince Maegor Targaryen, called Maegor the Cursebreaker, was the only son of Aegon I Targaryen with his sister-wife, Queen Visenya. He married his half-sister Marella, and had five children with her, four sons: Rhaenyr, Vhagar, Maelys and Maekar, and a daughter, Ellisaerys. Maegor was one of the three princes to set foot on Valyrian territory and return alive, from where he wrested the secret of the Valyrian steel forge. Thanks to this, he gave his wife a sword, called Warrior's Soul. He wielded his father's weapon, Blackfyre. He was a rider of the dragon Balerion
