Myles was a descendant of Ser Terrence Toyne, a knight of the Kingsguard caught abed with one of King Aegon IV's mistresses. Myles was known as "Blackheart" because of the sigil on his shield. He enjoyed the nickname and what it implied, as a captain should be feared by friends and foes alike; if people thought him cruel so much the better. However, Myles was not cruel. A soldier to the bone, he was firm but fair. His good friend Jon Connington considered Myles full of life.
A Dance with Dragons
When Jon Connington arrives at the Golden Company's encampment near Volon Therys, he contemplates the company's golden skulls ringing the captain-general's tent. One of them is Myles Toyne's skull, Jon's old friend. He goes to look at the Myles's skull and sees that death has robbed Myles of his ears, his nose and all his warmth, and that only his smile remains, transformed into a glittering grin.
