Kel'Dred the Collector

Kel'Dred is a Nathrezim currently serving in the Hellwrath Vanguard under Behamahl the Chaos-Gazer and Fel Lord Kathulon. He gets his title "The Collector" from the bodies he has amassed, switching between each one whenever he so pleases.

The Third War
Kel'Dred was a minor part in the Third War, following the commands of the more upper eschelon Dreadlords, and eventually being slew by Sylvanas' Forces, returning to the Twisting Nether.

The Burning Crusade
Kel'Dred spent many years in the Twisting Nether, before finding a way back into Azeroth. A mortal, Quincy Barolam, the son of a Stormwind Noble, would be seeking to learn about dark powers. He spent tirelessly to study demons and their practice. In Duskwood, he had wished to summon a lesser demon to this world under his control. What he had not realized is that he attracted the presence of Kel'Dred. Using this mortal as a way back, he waited for the human to begin his summoning ritual, and struck. He entered Azeroth, and fell the human. Using his body to influence Stormwind, he took up the name "Quincy Dred". He spent many years trying to influence the Noble House of Stormwind.

Mists of Pandaria
In the discovery of Pandaria, Dred had finally risen to his father's place in the Noble House, and made more attempts to sabotage the Alliance. He tried to hint at war against the Horde, especially with Garrosh's new moves on the world, but to no avail. Eventually, Quincy Dred was found out by a Paladin, Arlandrius McLaughlin, and was killed by Phineas Und Fogg and Arlandrius.

Legion
Kel'Dred finally came back for the full force of the Legion attacking Azeroth. He was at the Battle of the Broken Shore and witnessed Varian Wrynn's death. He was then assigned to Suramar to keep the Nightborne in check and to make sure they stayed fearing of the Legion's power. He tormented anyone who dared speak out against the Legion, and even took some of the Nightborne's bodies as his own way of enjoyment. He eventually started to find this almost like a hobby. He deemed himself "The Collector" for the amount of bodies he amassed. Kel'Dred was eventually forced out of the city when the Heroes of Azeroth stormed the place and forced the end of Gul'dan, fleeing to Argus. After the invasion of Argus, Kel'dred battled the forces of Azeroth and fled to Twisting Nether, refusing to be killed by such mortals. There he encountered Kathulon and joined up in ranks with him.

Hellwrath Vanguard
Kel'Dred now serves under Fel Lord Kathulon and the Darkglare Behamahl as a member of the Vanguard. While he still has his own agendas from time to time, Dred is loyal to Kathulon and plans to keep it this way.
