Mad King's Reign

A crown forged in shadow, burning the realm from within until only ash remained.

The Mad King's Reign marks the final, fraying decades of Aerys II Targaryen’s grip on the Seven Kingdoms. Once a promising heir who broke the Faith Militant and secured Dorne through diplomacy, Aerys spiraled into paranoid cruelty after surviving the Defiance of Duskendale. His capricious rule—marked by public executions and a grotesque obsession with fire—alienated his family, Small Council, and the nobility alike, igniting the spark that became Robert’s Rebellion.

Lore & Background

Madness crested during the years preceding Robert's Rebellion. Aerys demanded the heads of Eddard Stark and Robert Baratheon after they fled King's Landing, shattering the final bonds of loyalty and ensuring war was inevitable. His refusal to heed reason culminated in the execution of Lord Rickard Stark by fire and the death of his son Brandon as he pleaded for mercy. By the time Tywin Lannister marched on King's Landing under a banner of parley, Aerys had resolved to raze the city rather than yield, commanding his pyromancers to ignite wildfire caches buried beneath the Red Keep.

In Their Own Story

The throne room was cold, yet the air smelled of sulfur and old ash. Aerys sat hunched upon the Iron Throne, his fingers twitching as if grasping at invisible flames. 'Burn them all,' he whispered, his voice cracking like dry kindling. Ser Jaime Lannister stood behind him, hand resting on the pommel of his sword, watching the King's eyes dart toward the shadows where no enemies existed. The smell of burning flesh from a recent execution still clung to the stone walls, a grim reminder that in this court, justice was merely a pyre waiting for kindling.

Reader's Guide

The reign of Aerys II Targaryen dismantled the stability of a dynasty that had ruled for nearly three hundred years. The Defiance of Duskendale is widely considered the turning point; his captivity there shattered his sanity, replacing it with a deep-seated fear of betrayal. This paranoia fueled a reign of terror characterized by arbitrary executions and an obsession with wildfire, which he wielded as both weapon and symbol.

His treatment of the Great Houses united the realm against him. The burning of Lord Rickard Stark and the death of his son Brandon were not merely atrocities—they were the final sparks that ignited Robert's Rebellion, transforming a succession dispute into a desperate war to save the realm from tyranny.

The end of his reign remains one of Westeros' most infamous moments. As Tywin Lannister’s army breached King's Landing, Aerys ordered the wildfire caches ignited, intending to kill everyone rather than let them fall into enemy hands. It was Ser Jaime Lannister, a member of the Kingsguard sworn to protect him, who ended his life with a dagger.
