In 42 AC Lyle 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.
According to several chronicles of the event, Ser Harys lost his arm to Lord Lucifer Massey, one of the king's champions. One of these accounts state that he then tossed his battle-axe into his remaining hand and buried it between Lord Lucifer's eyes. Other chroniclers suggest Death's Head Harry simply died.
