Erryk was the twin brother of Ser Arryk Cargyll, who was also a member of the Kingsguard.
After the death of Viserys, Erryk joined Ser Steffon Darklyn and Ser Lorent Marbrand in siding with the blacks and joined the Queensguard of Rhaenyra Targaryen, instead of supporting King Aegon II Targaryen. Erryk slew and was slain by his brother during the Dance of the Dragons, as they had chosen opposite sides in the civil war. They supposedly had tears on their cheeks when they gave each other their mortal wounds.
