A Prison Without Jailers
Mimiron noticed abnormalities among the titan-forged and began to investigate. Loken sabotaged his workshop before that inquiry could expose him. Mechagnomes saved the inventor’s spirit in a mechanical body, but the attack removed a threat to Loken’s control.
Other keepers were subdued by force. Freya was overcome, and fire giants helped bring down Hodir’s defenses. Yogg-Saron imposed his will on guardians who had once helped secure his imprisonment.
Loken took command while Ulduar closed itself away. Its halls, gardens and workshops remained, giving the place the outward appearance of continuity. What had disappeared was the independence of the beings entrusted with its purpose.
