Queen Visenya Targaryen was the older of King Aegon I Targaryen's sisters. She was also one of his two wives, the other being her sister Rhaenys. During the War of Conquest, she rode her dragon, Vhagar, to battle.
Aegon's eldest sister was a passionate, temperamental woman. She was both stern and sensual, more voluptuous than her sister, more passionate, but with a dark and unforgiving side. Even those who loved her best found her stern, serious and unforgiving. She was a warrior, more comfortable in ring-mail than in silk, she was apt to dress as a warrior, with her long silver-gold hair in braided coils or bound in rings.
She wielded the Valyrian steel sword Dark Sister. She was described as having a "harsh beauty" and was reputed to have dabbled in sorcery. While her sister Rhaenys was the flirt, Visenya was the seductress. It is said that her brother-husband Aegon spent ten nights with Rhaenys for every one with her.
When her sister Rhaenys was killed a few years later during the Dornish War, the wrath of Aegon and Visenya was boundless. Aegon and Visenya's dragons consumed the Dornish castles in Dragon flame and placed bounties on the heads of Dornish lords.
Visenya largely oversaw the construction and planning of the city of King's Landing while Aegon was on Dragonstone.
Visenya was the mother of Maegor I Targaryen, her first and only child.
