Boss icon Malygos Malygos


Boss icon Flame Leviathan Flame Leviathan
This massive armored tank guards the courtyard entrance in Ulduar. The watcher Mimiron constructed the Flame Leviathan as part of his V0-L7R-0N weapons platform.
Boss icon Ignis the Furnace Master Ignis the Furnace Master
Like the other titan-forged creations in Ulduar, Ignis now serves the twisted will of the Old God Yogg-Saron. This imposing fire giant toils over the Colossal Forge, creating the iron armies that will conquer Azeroth in Yogg-Saron's name.
Boss icon Razorscale Razorscale
Veranus, broodmother of the proto-drakes in the Storm Peaks, served the keeper Thorim until she was captured by Loken and twisted into a vicious weapon. Under his master's orders, Ignis the Furnace Master fused iron plates onto Razorscale's hide to enhance her deadly strikes.
Boss icon XT 002 Deconstructor XT-002 Deconstructor
Engineered to patrol the Ulduar scrapyard, Mimiron invested his clockwork creation with rudimentary intellect that suited his duties. XT-002 has come to look upon himself as the keeper's son, and often throws tantrums like a petulant child.
Boss icon Assembly of Iron The Assembly of Iron
The iron legions of Loken are commanded by three fearsome generals, each representing a different titan-forged race. Stormcaller Brundir, Runemaster Molgeim, and the giant Steelbreaker fight in the name of the keeper's true master, the malevolent Yogg-Saron.
Boss icon Kologarn Kologarn
Loken commanded Ignis the Furnace Master to fashion this towering giant to guard the Shattered Walkway. His massive arms allow Kologarn to pulverize any intruders attempting to reach the inner sanctum.
Boss icon Auriaya Auriaya
Ulduar's archivist patrols the Observation Ring accompanied by ferocious cats. Years of solitude have weighed heavily on Auriaya, and the Old God's growing power seems to have destroyed the last shreds of her sanity.
Boss icon Hodir Hodir
The giant Hodir once presided over the Temple of Winter, lending his guidance to the frost giants in the Storm Peaks. Now the watcher dwells in an ice cave in the Halls of Winter, forced to serve the will of Yogg-Saron.
Boss icon Thorim Thorim
For years, Thorim believed that ice giants had murdered his beloved wife Sif. Thorim turned his wrath upon his allies and fell into despair. When he learned that his brother Loken was responsible from the crime, Loken captured Thorim and brought him to Ulduar, where the Old God clouded the keeper's mind.
Boss icon Freya Freya
The watcher Freya has served as protector of all living things, aided by three stoic elders. Though her conservatory remains lush and verdant, she too has succumbed to the Old God's maddening whispers.
Boss icon Mimiron Mimiron
A brilliant innovator, Mimiron has crafted countless mechanisms thoughout the history of Azeroth that have inspired awe and wonder. But since falling under Loken's disturbed influence, this watcher of Ulduar has only constructed machines of war and destruction.
Boss icon General Vezax General Vezax
Strange creatures known as faceless ones lurk in the depths of Ulduar. One of their mightiest commanders, General Vezax, guards the twisted passages leading to the Prison of Yogg-Saron.
Boss icon Yogg Saron Yogg-Saron
The lucid dream. The monster in your nightmares. The fiend of a thousand faces. All must bend to the master's will. Your petty quarrels only make him stronger.
Boss icon Algalon the Observer Algalon the Observer
Loken's death triggered a warning to the titan Pantheon that Azeroth had lost its Prime Designate. Algalon the Observer has been dispatched to evaluate the presence of systemic corruption. If necessary, the constellar will trigger the re-origination of the entire world, wiping out all its current inhabitants.
