Denys is an old man. He has blue-grey eyes and a long white beard. He has lost almost all his hair and his face is deeply lined. He still has his teeth and is graceful in his movement. In his communication with other people he is very courteous. He is considered cautious and chivalrous.
Denys was born at Seagard as a member of the Mallister family. He was a squire at twelve, a knight at eighteen and a champion at twenty-two years old. He has been the commander of the Shadow Tower for thirty-three years. He had been a candidate in the two last elections of Lord Commanders of the Night's Watch.
A Storm of Swords
Denys is a leading candidate to become the next Lord Commander of the Night's Watch to replace Jeor Mormont along with Cotter Pyke. Because the support between them is divided, Janos Slynt appears as a potential alternative. Though Cotter and Denys hate each other, both agree that Janos would be a worse choice. They are persuaded by Samwell Tarly to support Jon Snow instead.
