Erryk and his twin brother, Ser Arryk, were physically identical, even their fellow Kingsguards could not differenciate them.
After the death of Viserys, Erryk followed Ser Steffon Darklyn and Ser Lorent Marbrand in siding with the blacks and joined the Queensguard of Rhaenyra. His brother Arryk, however, supported Rhaenyra's rival, King Aegon II Targaryen.
Ser Criston, the Lord Commander of Aegon's Kingsguard, tasked Arryk with infiltrating Dragonstone in the guise of his twin, Erryk. It is uncertain whether he was to kill Rhaenyra or her children. The twins came upon each other in one of the hallways of the castle's citadel and fought to the death. According to songs, the brothers professed their love and died in one another's arms after fighting for an hour. Mushroom, however, claims they called each other traitor and were both mortally wounded within moments.
