Grand Maester Gawen, as depicted in Game of Thrones: Histories & Lore
Gawen was a maester of the Citadel who served as Grand Maester during the reigns of Kings Aegon I, Aenys I, and albeit briefly, Maegor I Targaryen.
Gawen served as Grand Maester for King Aegon I Targaryen, succeeding Grand Maester Lyonce in 12 AC. Gawen and Ser Osmund Strong, Aegonâs Hand of the King, were charged with raising walls around Kingâs Landing.
Gawen continued to hold the office of Grand Maester during the reign of Aegon Iâs heir, King Aenys I Targaryen. When Aenys fell ill at Dragonstone in late 41 AC, Gawen despaired of improving the kingâs condition.
Following the death of Aenys I, the elderly and grey-headed Gawen protested the coronation of Aenysâs half-brother, Maegor I Targaryen, by his mother, Visenya Targaryen. Gawen stated that following the laws of inheritance the crown should pass to Aenysâs oldest son, Prince Aegon. Maegor beheaded Gawen for his protests with Blackfyre. After Gawenâs death, there were no further protests at Dragonstone. Gawen was the first of three Grand Maesters who were executed during Maegorâs reign, the others being Myros and Desmond.
