Denys was one of the knights present at the Tourney at Ashford Meadow. He rode under the banner of House Marbrand. His name was given in the roll of arms.
Denys was commanded to arrest Lord Walderan Tarbeck by Lord Tytos Lannister, after the movements of Walderan angered Aegon V. Denys was attacked during the night by the force of Lord Roger Reyne, however, who cut down the old knight. Ser Reynard Reyne then convinced Tytos to pardon Roger, saying that he thought Denys and his men were outlaws.
Behind the Scenes Edit
In the unabridged version of the Westerlands chapter in The World of Ice and Fire, Denys is listed as the father of Jeyne Marbrand, who would marry Tytos. He became a firm supporter of Tytos as a result. In the published edition, however, Jeyne's father was Alyn Marbrand, who has "some relation" to Denys.
