King Aegon himself had more success. Marching eastward through the foothills, where runoff from the heights provided water and game was plentiful in the valleys, he took the castle Skyreach by storm, won Yronwood after a brief siege. The Lord of the Tor had recently died, and his steward surrendered without a fight. Farther east, Lord Toland of Ghost Hill sent forth his champion to challenge the king to single combat. Aegon accepted and slew the man, only to discover afterward that he had not been Toland’s champion, but his fool. Lord Toland himself was gone.

As was Meria Martell, the Princess of Dorne, when King Aegon descended upon Sunspear on Balerion, to find his sister Rhaenys there before him. After burning the Planky Town, she had taken Lemonwood, Spottswood, and Stinkwater, accepting obeisances from old women and children, but nowhere finding an actual enemy. Even the shadow city outside the walls of Sunspear was half-deserted, and none of those who remained would admit to any knowledge of the whereabouts of the Dornish lords and princess. “The Yellow Toad has melted into the sands,” Queen Rhaenys told King Aegon.

Aegon’s answer was a declaration of victory. In the great hall at Sunspear, he gathered together what dignitaries remained and told them that Dorne was now part of the realm, that henceforth they would be his leal subjects, that their former lords were rebels and outlaws. Rewards were offered for their heads, particularly that of the Yellow Toad, Princess Meria Martell. Lord Jon Rosby was named Castellan of Sunspear and Warden of the Sands, to rule Dorne in the king’s name. Stewards and castellans were named for all the other lands and castles the Conqueror had taken. Then King Aegon and his host departed back the way they had come, west along the foothills and through the Prince’s Pass.

They had hardly reached King’s Landing before Dorne erupted behind them. Dornish spearmen appeared from nowhere, like desert flowers after a rain. Skyreach, Yronwood, the Tor, and Ghost Hill were all recaptured within a fortnight, their royal garrisons put to the sword. Aegon’s castellans and stewards were allowed to die only after long torment. It was said that the Dornish lords had a wager over who could keep their captive alive the longest whilst dismembering them. Lord Rosby, Castellan of Sunspear and Warden of the Sands, had a kinder end than most. After the Dornishmen swarmed in from the shadow city to retake the castle, he was bound hand and foot, dragged to the top of the Spear Tower, and thrown from a window by none other than the aged Princess Meria herself.

   Soon only Lord Tyrell and his host remained. King Aegon had left Tyrell behind when he departed. Hellholt, a strong castle on the river Brimstone, was thought to be well situated to deal with any revolts. But the river was sulfurous, and the fish taken from it made the Highgardeners sick. House Qorgyle of Sandstone had never submitted, and Qorgyle spearmen cut down Tyrell’s foraging parties and patrols whenever they strayed too far west. The Vaiths of Vaith did the same to the east. When word of the Defenestration of Sunspear reached the Hellholt, Lord Tyrell gathered his remaining strength and set off across the sands. His announced intention was to capture Vaith, march east along the river, retake Sunspear and the shadow city, and punish Lord Rosby’s murderers. But somewhere east of the Hellholt amidst the red sands, Tyrell and his entire army disappeared. No man of them was ever seen again.

Aegon Targaryen was not a man to accept defeat. The war would drag on for another seven years, though after 6 AC the fighting degenerated into an endless bloody series of atrocities, raids, and retaliations, broken up by long periods of inactivity, a dozen short truces, and numerous murders and assassinations.

In 7 AC, Orys Baratheon and the other lords who had been taken captive on the Boneway were ransomed back to King’s Landing for their weight in gold, but on their return it was found that the Widow-lover had lopped off each man’s sword hand, so they might never again take up swords against Dorne. In retaliation, King Aegon himself descended on the mountain fastnesses of the Wyls with Balerion, and reduced half a dozen of their keeps and watchtowers to heaps of molten stone. The Wyls took refuge in caves and tunnels beneath their mountains, however, and the Widow-lover lived another twenty years.

   In 8 AC, a very dry year, Dornish raiders crossed the Sea of Dorne on ships provided by a pirate king from the Stepstones, attacking half a dozen towns and villages along the south shore of Cape Wrath and setting fires that spread through half the rainwood. “Fire for fire,” Princess Meria is reported to have said.

This was not something the Targaryens would allow to go unanswered. Later that same year, Visenya Targaryen appeared in the skies of Dorne, and Vhagar’s fires were loosed upon Sunspear, Lemonwood, Ghost Hill, and the Tor.

In 9 AC, Visenya returned again, this time with Aegon himself flying beside her, and Sandstone, Vaith, and the Hellholt burned.

The Dornish answer came the next year, when Lord Fowler led an army through the Prince’s Pass and into the Reach, moving so swiftly that he was able to burn a dozen villages and capture the great border castle Nightsong before the marcher lords realized the foe was upon them. When word of the attack reached Oldtown, Lord Hightower sent his son Addam with a strong force to retake Nightsong, but the Dornish had anticipated just that thing. A second Dornish army under Ser Joffrey Dayne came down from Starfall and attacked the city. Oldtown’s walls proved too strong for the Dornish to overcome, but Dayne burned fields, farms, and villages for twenty leagues around the city, and slew Lord Hightower’s younger son, Garmon, when the boy led a sortie against him. Ser Addam Hightower reached Nightsong only to find that Lord Fowler had put the castle to the torch and its garrison to the sword. Lord Caron and his wife and children had been carried back to Dorne as captives. Rather than pursue, Ser Addam returned at once to Oldtown to relieve the city, but Ser Joffrey and his army had melted back into the mountains as well.

Old Lord Manfred Hightower died soon after. Ser Addam succeeded his father as the Lord of the High Tower, as Oldtown cried out for vengeance. King Aegon flew Balerion to Highgarden to take counsel with his Warden of the South, but Theo Tyrell, the young lord, was most reluctant to contemplate another invasion of Dorne after the fate that had befallen his father.

   Once again the king unleashed his dragons against Dorne. Aegon himself fell upon Skyreach, vowing to make the Fowler seat “a second Harrenhal.” Visenya and Vhagar brought fire and blood to Starfall. And Rhaenys and Meraxes returned once more to the Hellholt…where tragedy struck. The Targaryen dragons, bred and trained to battle, had flown through storms of spears and arrows on many occasions, and suffered little harm. The scales of a full-grown dragon were harder than steel, and even those arrows that struck home seldom penetrated enough to do more than enrage the great beasts. But as Meraxes banked above the Hellholt, a defender atop the castle’s highest tower triggered a scorpion, and a yard-long iron bolt caught the queen’s dragon in the right eye. Meraxes did not die at once, but came crashing to earth in mortal agony, destroying the tower and a large section of the Hellholt’s curtain wall in her death throes.

Whether Rhaenys Targaryen outlived her dragon remains a matter of dispute. Some say that she lost her seat and fell to her death, others that she was crushed beneath Meraxes in the castle yard. A few accounts claim the queen survived her dragon’s fall, only to die a slow death by torment in the dungeons of the Ullers. The true circumstances of her demise will likely never be known, but Rhaenys Targaryen, sister and wife to King Aegon I, perished at the Hellholt in Dorne in the 10th year After the Conquest.
