|Alias||Willam the Wanderer|
|Allegiance|| Faith of the Seven|
|Died||In 42 AC, at King's Landing|
|Book(s)||The Sons of the Dragon (mentioned)|
In 42 AC, Ser Willam was stationed at the King's Landing chapter of the Warrior's Sons, based in the Sept of Remembrance. He fought in the trial of seven in which seven of the Warrior's Sons faced King Maegor I Targaryen and his six champions.
Ser Willam and Ser Damon Morrigen were the last Warrior's Sons standing against Maegor, whose six champions had all been killed. Badly wounded, the two were killed by Maegor with Blackfyre, the king's Valyrian steel sword. As he fell, however, Ser Willam dealt the king a terrible blow to the head, cracking his helm and leaving him insensate. However, this was not enough to kill him and Maegor was declared the winner.
