Prince Jacaerys soon brought the Lord of the Tides back into the fold by naming him the Hand of the Queen. Together he and Lord Corlys began to plan an assault upon King’s Landing.

With Sunfyre wounded near Rook’s Rest and unable to fly, and Tessarion with Prince Daeron in Oldtown, only two mature dragons remained to defend King’s Landing…and Dreamfyre’s rider, Queen Helaena, spent her days in darkness, weeping, and surely could not be counted as a threat. That left only Vhagar. No living dragon could match Vhagar for size or ferocity, but Jace reasoned that if Vermax, Syrax, and Caraxes were to descend on King’s Landing, even “that hoary old bitch” would be unable to withstand them.

Mushroom was less certain. “Three is more than one,” the dwarf claims to have told the Prince of Dragonstone, “but four is more than three, and six is more than four, even a fool knows that.” When Jace pointed out that Stormcloud had never been ridden, that Moondancer was but a hatchling, that Tyraxes was far away in the Vale with Prince Joffrey, and demanded to know where Mushroom proposed to find more dragons, the dwarf tells us he laughed and said, “Under the sheets and in the woodpiles, wherever you Targaryens spilled your silver seed.”

House Targaryen had ruled Dragonstone for more than two hundred years, since Lord Aenar Targaryen first arrived from Valyria with his dragons. Though it had always been their custom to wed brother to sister and cousin to cousin, young blood runs hot, and it was not unknown for men of the house to seek their pleasures amongst the daughters (and even the wives) of their subjects, the smallfolk who lived in the villages below the Dragonmont, tillers of the land and fishers of the sea. Indeed, until the reign of King Jaehaerys, the ancient right to the first night had been invoked mayhaps more oft on Dragonstone than anywhere else in the Seven Kingdoms, though Good Queen Alysanne would surely have been shocked to hear it.

Though the first night was greatly resented elsewhere, as Queen Alysanne had learned in her women’s counsels, such feelings were muted upon Dragonstone, where Targaryens were rightly regarded as being closer to gods than the common run of men. Here, brides thus blessed upon their wedding nights were envied, and the children born of such unions were esteemed above all others, for the Lords of Dragonstone oft celebrated the birth of such with lavish gifts of gold and silk and land to the mother. These happy bastards were said to have been “born of dragonseed,” and in time became known simply as “seeds.” Even after the end of the right of the first night, certain Targaryens continued to dally with the daughters of innkeeps and the wives of fishermen, so seeds and the sons of seeds were plentiful on Dragonstone.

It was to them that Prince Jacaerys turned, at the urging of his fool, vowing that any man who could master a dragon would be granted lands and riches and dubbed a knight. His sons would be ennobled, his daughters wed to lords, and he himself would have the honor of fighting beside the Prince of Dragonstone against the pretender Aegon II Targaryen and his treasonous supporters.

Not all those who came forward in answer to the prince’s call were seeds, nor even the sons or grandsons of seeds. A score of the queen’s own household knights offered themselves as dragonriders, amongst them the Lord Commander of her Queensguard, Ser Steffon Darklyn, along with squires, scullions, sailors, men-at-arms, mummers, and two maids. “The Sowing of the Seeds,” Munkun names the triumphs and tragedies that ensued (crediting the notion to Jacaerys himself, not Mushroom). Others prefer “the Red Sowing.”

The most unlikely of these would-be dragonriders was Mushroom himself, whose Testimony speaks at length of his attempt to mount old Silverwing, judged to be the most docile of the masterless dragons. One of the dwarf’s more amusing tales, it ends with Mushroom running across the ward of Dragonstone with the seat of his pantaloons on fire, and nigh drowning when he leapt into a well to quench the flames. Unlikely, to be sure…but it does provide a droll moment in what was otherwise a ghastly business.

Dragons are not horses. They do not easily accept men upon their backs, and when angered or threatened, they attack. Munkun’s True Telling tells us that sixteen men lost their lives during the Sowing. Three times that number were burned or maimed. Steffon Darklyn was burned to death whilst attempting to mount the dragon Seasmoke. Lord Gormon Massey suffered the same fate when approaching Vermithor. A man called Silver Denys, whose hair and eyes lent credence to his claim to be descended from a bastard son of Maegor the Cruel, had an arm torn off by Sheepstealer. As his sons struggled to staunch the wound, the Cannibal descended on them, drove off Sheepstealer, and devoured father and sons alike.

Yet Seasmoke, Vermithor, and Silverwing were accustomed to men and tolerant of their presence. Having once been ridden, they were more accepting of new riders. Vermithor, the Old King’s own dragon, bent his neck to a blacksmith’s bastard, a towering man called Hugh the Hammer or Hard Hugh, whilst a pale-haired man-at-arms named Ulf the White (for his hair) or Ulf the Sot (for his drinking) mounted Silverwing, beloved of Good Queen Alysanne. And Seasmoke, who had once borne Laenor Velaryon, took onto his back a boy of ten-and-five known as Addam of Hull, whose origins remain a matter of dispute amongst historians to this day.

Addam and his brother, Alyn (one year younger), had been born to a woman named Marilda, the pretty young daughter of a shipwright. A familiar sight about her father’s shipyards, the girl was better known as Mouse, for she was “small, quick, and always underfoot.” She was still sixteen when she gave birth to Addam in 114 AC, and barely eighteen when Alyn followed in 115. Small and quick as their mother, these bastards of Hull were both silver of hair and purple of eye, and soon proved to have “sea salt in their blood” as well, growing up in their grandsire’s shipyard and going to sea as ship’s boys before the age of eight. When Addam was ten and Alyn nine, their mother inherited the yards upon her own father’s death, sold them, and used the coin to take to the sea herself as the mistress of a trading cog she named Mouse. A canny trader and daring captain, by 130 AC Marilda of Hull owned seven ships, and her bastard sons were always serving on one or the other.

That Addam and Alyn were dragonseed no man who looked upon them could doubt, though their mother steadfastly refused to name their father. Only when Prince Jacaerys put out the call for new dragonriders did Marilda at last break her silence, claiming both boys were the natural sons of the late Ser Laenor Velaryon.

They had his look, it was true, and Ser Laenor had been known to visit the shipyard in Hull from time to time. Nonetheless, many on Dragonstone and Driftmark were skeptical of Marilda’s claim, for Laenor Velaryon’s disinterest in women was well remembered. None dared name her liar, however…for it was Laenor’s own father, Lord Corlys himself, who brought the boys to Prince Jacaerys for the Sowing. Having outlived all of his children and suffered the betrayal of his nephews and cousins, the Sea Snake seemed more than eager to accept these newfound grandsons. And when Addam of Hull mounted Ser Laenor’s dragon, Seasmoke, it seemed to prove the truth of his mother’s claims.

It should not surprise us, therefore, that Grand Maester Munkun and Septon Eustace both dutifully assert Ser Laenor’s parentage…but Mushroom, as ever, dissents. In his Testimony, the fool puts forth the notion that “the little mice” had been sired not by the Sea Snake’s son, but by the Sea Snake himself. Lord Corlys did not share Ser Laenor’s erotic predispositions, he points out, and the Hull shipyards were like unto a second home to him, whereas his son visited them less frequently. Princess Rhaenys, his wife, had the fiery temperament of many Targaryens, Mushroom says, and would not have taken kindly to her lord husband fathering bastards on a girl half her age, and a shipwright’s daughter besides. Therefore his lordship had prudently ended his “shipyard trysts” with Mouse after Alyn’s birth, commanding her to keep her boys far from court. Only after the death of Princess Rhaenys did Lord Corlys at last feel able to bring his bastards safely forward.

In this instance, it must be said, the tale told by the fool seems more likely than the versions offered by septon and maester. Many and more at Queen Rhaenyra’s court must surely have suspected the same. If so, they held their tongues. Not long after Addam of Hull had proved himself by flying Seasmoke, Lord Corlys went so far as to petition Queen Rhaenyra to remove the taint of bastardy from him and his brother. When Prince Jacaerys added his voice to the request, the queen complied. Addam of Hull, dragonseed and bastard, became Addam Velaryon, heir to Driftmark.
