The Forgotten Royal Bastard Who Conspired
Sir Roger Clarendon was a royal secret, born as the illegitimate son of a famous prince. Despite his noble blood, he eventually turned against the crown as a plotter.
As the son of Edward the Black Prince, Roger occupied a strange social space between royalty and commoner. His decision to join a conspiracy against his own half-brother, King Henry IV, shows how unstable royal legacies could be. He was eventually executed for treason, marking a bloody end to his hidden life. It is rare to find such a direct blood link to a legendary warrior prince ending in a plot against the throne.
