Character and Appearance
Denys was a "renowned jouster, handsome and gallant and brimming with courtesy".
Denys hailed from a poor branch of House Arryn. He married a distant cousin who descended from the main Arryn branch. Since Denys had "Arryn" as a surname and had married the eldest surviving daughter of Alys Arryn he was considered the next heir of the house after Elbert Arryn. He was named Keeper of the Gates of the Moon by Lord Jon Arryn, replacing Jon's brother, Ser Ronnel. When Elbert was murdered by King Aerys II Targaryen Denys was made heir.
