|Title||Lord of Duskendale|
|Spouse||Lady Serala of Myr|
|Book(s)||A Feast for Crows (mentioned)|
According to semi-canon sources, Lord Denys asked King Aerys II for certain rights for his citizens and a new town charter for Duskendale. The king refused and Denys refused to pay taxes to the crown. This led to an escalation of events that saw the capture of Aerys and the death of Ser Gwayne Gaunt of the Kingsguard by Ser Symon Hollard during the taking.
Denys continued his defiance, even as the might of the Seven Kingdoms, led by the King's Hand Lord Tywin Lannister, sat outside his walls. Tywin's forces were strong enough to storm Duskendale, but Denys threatened to kill the king if that happened. The Defiance ended when Ser Barristan Selmy sneaked into the Dun Fort, the seat of House Darklyn, and rescued his king. Denys, no longer having a hostage, immediately opened his gates and begged for mercy. He was beheaded, as was the rest of his family, while his wife, Serala of Myr, was burned. Denys was still young at the time of his death. Not one lorldly Darklyn remained alive.
Despite the woe he brought on them, Lord Denys is still loved by the people of Duskendale, who blame his wife Serala for the Defiance and thought that nothing would have happened had Lord Denys instead married a Stokeworth or Staunton. It was said that Lady Serala had filled her husband with Myrish poison and enslaved him with her lady parts, until he rose against King Aerys.
