Early Life and Reputation as the Tall

Physical Presence and Status

Duncan earned his moniker from his extraordinary height, which set him apart even among knights and lords. His size and strength made him a formidable jouster and a respected figure in tournaments across the realm.

Service to the Crown

As a member of a cadet branch of House Targaryen, Duncan served as a hedge knight before earning royal favor. He became a close companion and sworn shield to Prince Aerys, demonstrating loyalty that would later complicate his fate.

The Accusation and Trial by Combat

Murder of a Stableboy

The case that doomed Duncan began with the alleged murder of a stableboy linked to House Clegane. The accused was Ser Gregor Clegane, whose brutal reputation made him a natural suspect in the violent death.

Demand for Trial by Combat

Under the old right of trial by combat, Gregor Clegane challenged any knight to fight in his place. Duncan, bound by honor and duty, accepted the role of champion despite the obvious danger posed by Gregor's size and ferocity.

The Trial by Seven Combat

Rules of Trial by Seven

In a Trial by Seven, each side selects seven champions to represent them in combat. Duncan stood with allies from the Faith and the court while Clegane relied on brute strength and the favor of the king.

Battle Outcome

During the brutal contest, Duncan was grievously wounded multiple times, suffering broken bones and deep cuts. Although he fought valiantly, he succumbed to his injuries shortly after the match, marking a turning point in the reign of King Aerys.

Political Consequences of Duncan's Death

Royal Authority and Pardon Denied

King Aerys refused to grant Clegane a royal pardon, which many believed was a calculated move to show strength. This decision deepened existing tensions within the royal court and fueled whispered dissent against the Iron Throne.

Impact on House Targaryen

The loss of Duncan damaged the prestige of House Targaryen among the nobility. It also strained relationships with trusted retainers and hinted at the growing instability that would eventually lead to open rebellion and the fall of the dynasty.
