Aegon's Conquest

Fire and blood forged a unified realm from seven warring kingdoms.

Aegon’s Conquest shattered the feudal fragmentation of Westeros, binding six independent kingdoms under one crown for the first time in recorded history. Commanding three dragons and his sisters-wives, Visenya and Rhaenys, Aegon Targaryen turned the tide of warfare with fire and blood, leaving only Dorne standing against the new order.

Lore & Background

The campaign was defined by the psychological terror of dragonfire, rendering traditional shields and walls obsolete. At the Field of Fire in the Reach, Balerion's flames incinerated King Mern IX Gardener and his entire host, extinguishing House Gardener forever; Highgarden surrendered immediately after, elevating House Tyrell to Wardens of the South. While most lords bent the knee or burned, Dorne's princes vanished into red deserts and mountain passes, utilizing guerrilla warfare to repel invaders. Though Daeron I briefly conquered Dorne in 157 AC, he was killed by a rebellion shortly after, allowing Dorne to regain independence until it was permanently united via marriage alliance under Daeron II around 203 AC.

In Their Own Story

The wind howled across the Blackwater Rush, carrying the scent of sulfur and wet ash. Aegon stood atop his black dragon, Balerion, looking down at the retreating armies of the Riverlands. Below, the charred remains of Harrenhal still smoked, a monument to the folly of defying dragonfire. 'Seven kingdoms,' he murmured to Visenya, who soared beside him on Vhagar, her armor gleaming in the grey light. 'One throne.' The silence that followed was not peace, but the heavy, expectant quiet of a world holding its breath before the dawn of a new age.

Reader's Guide

Marking the dawn of Targaryen rule, Aegon I landed on Blackwater Bay with three dragons, raising King's Landing as the new capital. The conquest relied on overwhelming aerial dominance; traditional armies could not withstand the beasts. In the Reach, the fall of House Gardener allowed House Tyrell to rise as Wardens of the South. Following the campaign, Aegon forged the Iron Throne from the swords of his vanquished foes using Balerion’s fire and established the Kingsguard to protect the monarch. He reorganized the realm's administration, laying a foundation that would define Westerosi history for generations. Dorne remained unconquered throughout this era, its Martell lords using hit-and-run tactics to frustrate Targaryen occupation until Daeron I's campaign centuries later.
