Yet there was darkness in Visenya Targaryen. To most of the world, she presented the grim face of a warrior, stern and unforgiving. Even her beauty had an edge to it, her admirers said. The oldest of the three heads of the dragon, Visenya was to outlive both of her siblings, and it was rumored that in her later years, when she could no longer wield a sword, she delved into the dark arts, mixing poisons and casting malign spells. Some even suggest that she might have been a kinslayer and a kingslayer, though no proof has ever been offered to support such calumnies.

It would be a cruel irony if true, for in her youth no one did more to protect the king. Visenya twice wielded Dark Sister in Aegon’s defense when he was set upon by Dornish cutthroats. Suspicious and ferocious by turns, she trusted no one but her brother. During the Dornish War, she took to wearing a shirt of mail night and day, even under her court clothes, and urged the king to do the same. When Aegon refused, Visenya grew furious. “Even with Blackfyre in your hand, you are only one man,” she told him, “and I cannot always be with you.” When the king pointed out that he had guardsmen around him, Visenya drew Dark Sister and slashed him across the cheek so quickly the guards had no time to react. “Your guards are slow and lazy,” she said. “I could have killed you as easily as I cut you. You require better protection.” King Aegon, bleeding, had no choice but to agree.

   Many kings had champions to defend them. Aegon was the Lord of the Seven Kingdoms; therefore, he should have seven champions, Queen Visenya decided. Thus did the Kingsguard come into being; a brotherhood of seven knights, the finest in the realm, cloaked and armored all in purest white, with no purpose but to defend the king, giving up their own lives for his if need be. Visenya modeled their vows on those of the Night’s Watch; like the black-cloaked crows of the Wall, the White Swords served for life, surrendering all their lands, titles, and worldly goods to live a life of chastity and obedience, with no reward but honor.

So many knights came forward to offer themselves as candidates for the Kingsguard that King Aegon considered holding a great tourney to determine which of them was the most worthy. Visenya would not hear of it, however. To be a Kingsguard knight required more than just skill at arms, she pointed out. She would not risk placing men of uncertain loyalty about the king, regardless of how well they performed in a melee. She would choose the knights herself.

The champions she selected were young and old, tall and short, dark and fair. They came from every corner of the realm. Some were younger sons, others the heirs of ancient houses who gave up their inheritances to serve the king. One was a hedge knight, another bastard born. All of them were quick, strong, observant, skilled with sword and shield, and devoted to the king.

These are the names of Aegon’s Seven, as written in the White Book of the Kingsguard: Ser Richard Roote; Ser Addison Hill, Bastard of Cornfield; Ser Gregor Goode; Ser Griffith Goode, his brother; Ser Humfrey the Mummer; Ser Robin Darklyn, called Darkrobin; and Ser Corlys Velaryon, Lord Commander. History has confirmed that Visenya Targaryen chose well. Two of her original seven would die protecting the king, and all would serve with valor to the end of their lives. Many brave men have followed in their footsteps since, writing their names in the White Book and donning the white cloak. The Kingsguard remains a synonym for honor to this day.

   Sixteen Targaryens followed Aegon the Dragon to the Iron Throne, before the dynasty was at last toppled in Robert’s Rebellion. They numbered amongst them wise men and foolish, cruel men and kind, good men and evil. Yet if the dragon kings are considered solely on the basis of their legacies, the laws and institutions and improvements they left behind, the name of King Aegon I belongs near the top of the list, in peace as well as war.

King Aegon I Targaryen took both of his sisters to wife. Rhaenys and Visenya were dragonriders, with the silver-gold hair, purple eyes, and beauty of true Targaryens. Elsewise, the two queens were as unlike each other as any two women could be…save in one other respect. Each of them gave the king a son.

Aenys came first. Born in 7 AC to Aegon’s younger wife, Rhaenys, the boy was small at birth and sickly. He cried all the time, and it was said that his limbs were spindly, his eyes small and watery, and that the king’s maesters feared for his survival. He would spit out the nipples of his wet nurse, and give suck only at his mother’s breasts, and rumors claimed that he screamed for a fortnight when he was weaned. So unlike King Aegon was he that a few even dared suggest that His Grace was not the boy’s true sire, that Aenys was some bastard born of one of Queen Rhaenys’s many handsome favorites, the son of a singer or a mummer or a mime. And the prince was slow to grow as well. Not until he was given the young dragon Quicksilver, a hatchling born that same year on Dragonstone, did Aenys Targaryen begin to thrive.

Prince Aenys was three when his mother, Queen Rhaenys, and her dragon, Meraxes, were slain in Dorne. Her death left the boy prince inconsolable. He stopped eating, and even began to crawl as he had when he was one, as if he had forgotten how to walk. His father despaired of him, and rumors flew about the court that King Aegon might take another wife, as Rhaenys was dead and Visenya childless and perhaps barren. The king kept his own counsel on these matters, so no man could say what thoughts he might have entertained, but many great lords and noble knights appeared at court with their maiden daughters, each more comely than the last.

   All such speculation ended in 11 AC, when Queen Visenya suddenly announced that she was carrying the king’s child. A son, she proclaimed confidently, and so he proved to be. The prince came squalling into the world in 12 AC. No newborn was ever more robust than Maegor Targaryen, maesters and midwives agreed; his weight at birth was almost twice that of his elder brother.

The half-brothers were never close. Prince Aenys was the heir apparent, and King Aegon kept him close by his side. As the king moved about the realm from castle to castle, so did the prince. Prince Maegor remained with his mother, sitting by her side when she held court. Queen Visenya and King Aegon were oft apart in those years. When he was not on a royal progress, Aegon would return to King’s Landing and the Aegonfort, whilst Visenya and her son remained on Dragonstone. For this reason, lords and commons alike began to refer to Maegor as the Prince of Dragonstone.

Queen Visenya put a sword into her son’s hand when he was three. Supposedly the first thing he did with the blade was butcher one of the castle cats, men said…though more like this tale was a calumny devised by his enemies many years later. That the prince took to swordplay at once cannot be denied, however. For his first master-at-arms his mother chose Ser Gawen Corbray, as deadly a knight as could be found in all the Seven Kingdoms.

Prince Aenys was so oft in his sire’s company that his own instruction in the chivalric arts came largely from the knights of Aegon’s Kingsguard, and sometimes the king himself. The boy was diligent, his instructors agreed, and did not want for courage, but he lacked his sire’s size and strength, and was never more than adequate as a fighter, even when the king pressed Blackfyre into his hands, as he did from time to time. Aenys would not disgrace himself in battle, his tutors told one another, but no songs would ever be sung about his prowess.
