The Dragonflayer clan is a vrykul clan under the control of the slumbering King Ymiron. They have taken up residence in Utgarde Keep, on the shores of Lake Cauldros, within the Howling Fjord of Northrend. Ingvar the Plunderer commands the clan's dragon-riders in their attacks against the town of Valgarde.
Thousands of years ago, the Dragonflayer clan fought the jalgar and drove them from their lands. They found themselves afflicted by the curse of flesh and their king, Ymiron, blamed the absent Keepers for it. He ordered the weak and ugly children born to Dragonflayer women be killed, but some vrykul could not bear to do it and secreted them away to Tirisfal Glades, where legends told that other vrykul had fled there with Tyr long ago. In an effort to stave off the curse of flesh, the Dragonflayers went to sleep beneath northern Kalimdor in facilities such as Gjalerbron.
Attacks on Alliance Settlements
They began attacking Valgarde, the primary Alliance forteress in eastern Northrend. They captured a number of Alliance soldiers and either left them impaled  or imprisoned in Wyrmskull Village.
Into the Utgarde Catacombs
Some Dragonflayer pitted their prisoners against powerful vrykul gladiators, then threw out their corpses for a necromancer to raise as ghouls when they lost.An Alliance force entered the Utgarde Catacombs where this was taking place, freeing the prisoners and defying the vrykul champions in . They also took the .
Queen Angerboda was found by the Forsaken to be awakening her husband King Ymiron. She was killed before she could finish the task and the Lich King spirited the still-dormant king away to Utgarde Pinnacle, promising that if her killers were foolish enough to follow him there, he would have the chance to avenge his wife.
Plague of Halgrind
The Royal Apothecary Society designed a new Forsaken Blight, capable of killing all life in Halgrind. Thorvald, the chieftain of the town, fled when the Forsaken took the city. The remaining vrykul, while not dropping dead from exposure, found themselves trapped and slowly killed. He was killed later for his blood.
The Dragonflayers in Voldrune in the Grizzly Hills imbued talismans with flame to control proto-drakes. As the vrykul prepared for war, they were killed by adventurers who took command of Flamebringer to kill Thane Torvald Eriksson.
Utgarde Keep instances
Adventurers ventured into the halls of Utgarde Keep and its pinnacle to permanently remove the threat posed by the Dragonflayer. Despite fighting alongside a few members of the Ymirjar, the elite army of vrykul loyal to the Lich King, they were almost entirely wiped out. In the end, even their king, Ymiron, would fall at the invaders' hands.
