Morgil's death, as depicted in Game of Thrones: Histories & Lore
|Died||In 172–183 AC|
Ser Morgil is renowned for slandering Queen Naerys Targaryen and being killed by her brother, Prince Aemon the Dragonknight, in trial by combat. According to Grand Maester Kaeth's Lives of Four Kings, these accusations were instigated by Aegon IV himself, who was at the time quarreling with his son and heir, Prince Daeron.
Well, the singers embroider everything, but there was a Ser Morgil and he did accuse Naerys of various things... probably adultery and treason with Aemon, but I haven't nailed all that down yet....
