The dreadlord Detheroc, and his two brothers, Balnazzar and Varimathras, were left to watch over the Legion's holdings in Lordaeron when Archimonde and the main force of the Legion left for Kalimdor to deal with the fleeing orcs and humans, as well as the night elves who had defeated them in ages past. While Detheroc was the leader of the three Dreadlord Insurgents, he was not necessarily the most powerful.
In the aftermath of the Third War, Detheroc began to notice that much time had passed without hearing a word from Archimonde. One day, Arthas Menethil stormed into the palace and informed them that their Legion was defeated, and that their deaths would seal that fate. They were able to flee before he could strike. Hiding in Tirisfal Glades, they coerced Sylvanas Windrunner into assisting them, and planned a coup to take back Lordaeron and rule what were now known as the Plaguelands. Detheroc and his brothers assumed control of the Capital City and ambushed Arthas, but the resilient death knight battled his way through their forces and fled across the sea to his master in Northrend.
With Arthas gone, Detheroc and the other dreadlords concentrated their power in Lordaeron. When Varimathras asked Sylvanas to join their new order she refused, butchered his forces, and turned him to her own side. Detheroc was not so easily defeated. He used his powers of domination to control the human general, Othmar Garithos, and when Sylvanas launched her next attack upon him he turned Garithos and his forces loose on her. With Varimathras at her side, Sylvanas managed to keep Garithos at bay as she stormed into Detheroc's base and tore him apart.

While leading an attack on Balnazzar in Stratholme, Eligor Dawnbringer remarked that any dreadlord slain on the mortal plane is merely banished to the Twisting Nether and opined that Detheroc and his brothers may return some day. His theory proved true several years later when, just before the battle for the Broken Shore, SI:7 discovered a trap set by the Burning Legion. Before they could warn the Alliance, Detheroc ambushed the SI:7 agents and captured their leader, Mathias Shaw, and impersonated him. Amber Kearnen managed to get away and tried to warn the Uncrowned but Detheroc, posing as Shaw, ordered SI:7 agents to kill her.
As Shaw, Detheroc spoke lies to Anduin Wrynn about the Horde and manipulated the new king into preparing Stormwind's armies to attack them, intent on instigating another conflict between the Alliance and Horde when the world could least afford it. To cover his tracks, Detheroc placed wanted posters of the members of the Uncrowned all over Stormwind, claiming they had conspired with the Burning Legion and offering rewards for their deaths. After a member of the Uncrowned freed the real Mathias Shaw, Fleet Admiral Tethys snuck them and Taoshi into Stormwind during the night. The three rogues made their way to SI:7 headquarters, where they exposed and killed Detheroc.
- It's been months since we last heard from Lord Archimonde. I grow tired of watching over these rotting undead! What are we still doing here?
- Never! This isn't over, human!
- Balnazzar: "Lady Sylvanas. We are pleased that you came."
- Sylvanas Windrunner: "How could I not? For some reason I no longer hear the Lich King's voice in my head. My will is my own once again."
- Sylvanas Windrunner: "You dreadlords seem to know why."
- Varimathras: "We've discovered that the Lich King is losing his power! As it wanes, so too does his ability to command undead such as you."
- Sylvanas Windrunner: "And what of King Arthas? What about his powers?"
- Balnazzar: "Though his runeblade, Frostmourne, carries powerful enchantments, Arthas' own powers will fade in time. It is inevitable."
- Sylvanas Windrunner: "You seek to overthrow him, and you want my help to do it."
- Detheroc: "The Legion may be defeated, but we are the Nathrezim! We'll not let some upstart human get the best of us! Arthas must fall!"
- Balnazzar: "The lich, Kel'Thuzad, is far too loyal to betray his master. But you, on the other hand..."
- Sylvanas Windrunner: "Hate him. I have my own reasons for seeking vengeance. Arthas murdered my people and turned me into this... monstrosity."
- Sylvanas Windrunner: "I may take part in your bloody coup, but I will do so in my own way. "
- Balnazzar: "I, for one, do not trust her. Her heart is still elven. She will never side with us. "
- Varimathras: "Don't be too hasty. She has great spirit, but her hatred for Arthas will ultimately serve our cause."
- Detheroc: "Agreed. Well, if that's settled--let the festivities commence."
- There's been a change of plans, King Arthas. You're not going anywhere.
- Traitor! How could you betray us like this? We could have ruled this land together!
- Come and face me, little banshee!
- You are clever, Sylvanas, but you are no match for me.
- You rebels rush headlong to your deaths!
- I am Nathrezim! My will cannot be denied!
