- ―Trevyr Blackgard
Dyron Blackgard is a recurring character in the third, fourth, fifth and sixth seasons. Dyron is the second son of Lord Trevyr Blackgard of Blackgard and his wife Lady Laenah, brother of Trovan Blackgard, Lucan Blackgard, Eddin Blackgard and Elyse Blackgard, and the "half-brother" of Ardrew Ashes. He is married to Talya Blackgard.
- "Elyse is crying upstairs. I hear horses coming to the castle. Ser Brant, I think it's time you told your lord what everyone seems to know."
- ―Trevyr Blackgard, interrogating Brant Tymber about Dyron's death.
Dyron receives a letter from one of his scouts in Rosby he sent to look after his sister, Elyse. In the letter, the scout describes that Elyse was once again tormented by Marlen. Enraged, Dyron quickly leaves Blackgard and heads for Rosby, before Brant can stop him.
Once en route to Rosby, Dyron finds two carriage drivers in an argument blocking the road. Dyron dismounts from his horse and yells at the carriage drivers to clear the road. One of the drivers turns to Dyron and sticks a blade in his stomach. Intestines fall out from Dyron's abdomen and he falls dead to the ground. The carriage drivers leave and three Blackgard horsemen find Dyron's corpse in the middle of the road.
Dyron's body is taken back to Blackgard where the Silent Sisters prepare him for the funeral. Trevyr arises from his wheelchair for the first time and demands a meeting with the heads of his vassals.
As is tradition, Dyron has been mummified and buried inside the Blackgard Ancestral Tomb.
