King of Winter and Ice (asoiaf)

While Aegon dealt with Harrenhal, the greater part of his host crossed the Blackwater Rush heading south for Storm's End under the command of Orys Baratheon, with Queen Rhaenys Targaryen accompanying him astride Meraxes. While the Storm King Argilac Durrandon gathered his bannermen to Storm's End, pirates from the Stepstones raided Cape Wrath and Dornishmen from the Red Mountains attacked the Dornish Marches.

Lords Errol, Fell and Buckler, bannermen of Argilac the Arrogant, surprised the advance elements of Orys's host as they were crossing the Wendwater, cutting down more than a thousand men before retreating back into the trees. Rhaenys unleashed Meraxes and set the forest ablaze, killing Lord Errol. Word of King Harren's end having reached Storm's End, Argilac rode north to meet his foes in the field. After being advised through Rhaenys's reconnaissance, Orys fortified a strong position on the hills south of Bronzegate and waited for Argilac's stormlanders.

In what became known as the Last Storm, Argilac attacked the Baratheon and Targaryen forces during a howling gale. The Storm King and his knights broke through Orys's center during their third charge, but they then faced Queen Rhaenys. Meraxes's dragonflame killed the personal guard of Argilac, who was thrown from the saddle. Orys offered him to yield, but Argilac cursed him instead. After Orys slew the wounded Storm King in single combat, the stormlanders threw down their swords and fled.

Argilac's daughter, Argella Durrandon, barred the gates of Storm's End and declared herself Storm Queen. The castle's soldiers, however, eventually delivered her to Orys's camp naked at night. It is said that Orys covered her with his own cloak and executed every man in the garrison for breaking their oaths and dishonoring Argella. Orys took Argella as his wife and chose the words and sigil of House Durrandon for the new House Baratheon. Aegon named Orys the Lord Paramount of the Stormlands and made him Lord of Storm's End.

Following the death of Harren the Black at Harrenhal, Aegon sent his sister-queen Visenya to demand the submission of Crackclaw Point. Its lords understood they had no chance, so they laid their swords at her feet. Visenya took them as her own men, and they would owe no fealty but to the Iron Throne. They bent the knee to her without qualm, and in return she promised them that they would be direct vassals of the Targaryens. This angered House Celtigar as they coveted the lands of Cracklaw Point and wanted them as their reward for their support of Aegon and House Targaryen.

Meanwhile, the two great western kings made common cause and assembled their own armies. From Highgarden marched Mern IX Gardener, King of the Reach, with a mighty host from the Reach. Beneath the walls of Goldengrove he met Loren Lannister, King of the Rock, leading his own host from the Westerlands. Together they commanded the mightiest host ever seen in Westeros: an army fifty-five thousand strong, including over five thousand knights. The Two Kings did not linger at Goldengrove, marching north.

Advised of their coming in his camp beside the Gods Eye, Aegon gathered his own forces and advanced to meet them. He commanded only one-fifth the men and was able to move his host more quickly. At the town of Stoney Sept, both his queens joined him with their dragons, Rhaenys from Storm's End and Visenya from Crackclaw Point.

The two armies came together amongst the wide-open plains south of the Blackwater Rush. House Gardener commanded the center of the allied army, with House Lannister the right and House Oakheart the left. The charge of their knights began to break the Targaryen army, but Aegon and his sisters attacked from the air with their dragons. Over five thousand died in this Field of Fire, and tens of thousands were wounded. Mern and his kin all were all mortally wounded from the battle, ending House Gardener. Loren managed to escape, but he and the Lannister bannermen yielded to Aegon after being captured the following day. Loren was named Aegon's Warden of the West.

Aegon marched at once for Highgarden, hoping to secure its surrender. He found the castle in the hands of its steward, Harlan Tyrell, who yielded the castle without a fight and pledged his support to Aegon. In reward Harlan was granted Highgarden and named Warden of the South and Lord Paramount of the Mander. Harlan also in a bid to secure his rule married the last surviving Gardener, Mern's daughter, Joanna to his son and heir Theo Tyrell before even the arrival of Aegon. But still many houses were not impressed by this move and staked their claim on Highgarden, House Hightower and Florent the chief among them along with Tarly.

Aegon's next planned to secure Oldtown and Dorne, but while at Highgarden he learned that Torrhen Stark, King in the North, had crossed the Neck with an army of northmen some 40 thousand strong. In response, Aegon and his queens gathered the lords and knights who had already yielded to House Targaryen.

When Torrhen's northmen reached the Trident, they found a Targaryen host half again their size south of the river, including men from the Reach, riverlands, stormlands, and westerlands. Some northern lords wanted to attack, while others wanted to fortify Moat Cailin. Brandon Snow offered to assassinate the sleeping Targaryen dragons. With Harrenhal and the Field of Fire in mind, however, Torrhen instead sent Brandon with maesters to negotiate a peace. Torrhen was able to secure many benefits for the North like lower taxes than other kingdoms, better grain prices during winter, support for the Night's Watch, which has till now only been funded by Houses of North and not involving it in the Crown's politics. The following day Torrhen crossed the Trident and yielded to Aegon, becoming Lord of Winterfell and Warden of the North. Torrhen has subsequently been known as the King Who Knelt.

In response to the Targaryen successes, Sharra Arryn, Queen Regent of the Vale, strengthened the defenses at Gulltown, moved a host to the Bloody Gate, and tripled the garrisons at the way-castles which guard the Eyrie. House Arryn felt secure in the Vale. Visenya Targaryen, however, flew Vhagar to the Eyrie's inner courtyard, and Sharra found sitting on the knee of Aegon's queen her son Ronnel, who asked to fly on the dragon. After flying three times around the Giant's Lance on Vhagar, Ronnel Arryn who took off as a King landed as a lord and became the Lord of the Eyrie and Aegon's Warden of the East.

When word of Aegon's Landing reached Oldtown, the High Septon locked himself in the Starry Sept for seven days and nights, seeking after the guidance of the Seven. On the seventh day, the Crone allegedly lifted her golden lamp and showed that Oldtown would burn if the city opposed the Targaryens. Manfred Hightower, Lord of the Hightower, decided not to oppose Aegon by force of arms and House Hightower therefore was not involved with the Field of Fire.

When Aegon and his host approached Oldtown they found the city gates open and Lord Hightower, who did not answer his King's call to arms when he rode with the combined Reach-Westerlands host, came riding forth in submission. Three days later in the Starry Sept, the High Septon anointed Aegon with the seven oils, placed a crown upon his head and proclaimed him Aegon of House Targaryen, the First of His Name, King of the Andals, 'the Rhoynar' (not yet), and the First Men, Lord of the Seven Kingdoms, and Protector of the Realm. This marked the official beginning of Aegon's reign.

Now in control of six of the Seven Kingdoms and known as the Conqueror, Aegon I Targaryen announced he would rule not from Dragonstone or Oldtown, but from the Aegonfort and the new city growing around it, King's Landing. Aegon had melted the swords of those who had opposed him into the Iron Throne, a reminder of their submission to the Targaryens. Queen Visenya Targaryen led the suppression of the Sistermen's Rebellion.

The Iron Islands fell into chaos after the death of Harren the Black. In 2 AC, Aegon led the invasion of the Iron Islands and forced the surviving lords of the ironborn to submit. Aegon allowed them to choose Lord Vickon Greyjoy as the new Lord of the Iron Islands. Dorne remained unconquered, however. Aegon continued the Wars of Conquest in 4 AC, beginning the bloody and unsuccessful First Dornish War.

During Aegon's Conquest, Queen Rhaenys Targaryen was sent to conquer Dorne in her brother's name. Instead of confronting the Dornish spearmen guarding the Prince's Pass in the Red Mountains, Rhaenys flew over the pass on her dragon Meraxes to Vaith and Godsgrace. She found the castles abandoned and continued her journey to the Planky Town, where only women and children remained. At Sunspear, the seat of House Martell, she found Meria Martell, the aged Princess of Dorne, waiting in her otherwise abandoned castle. Meria defied Rhaenys, stating that they would neither fight nor kneel. Rhaenys warned the Princess of Dorne that the Targaryens would return "with fire and blood", but Meria replied simply with "You may burn us, my lady, but you will not bend us, break us, or make us bow. This is Dorne. You are not wanted here. Return at your own peril." Rhaenys departed, but the Targaryens subsequent made no direct attempt to conquer the harsh deserts of Dorne, instead focusing on their main conquests in the heart of Westeros.

As such, Dorne was the only kingdom not to be conquered by Aegon I Targaryen in his initial conquest.
