“You were right to bring this to me, Vikstone. You must venture to Gjalerbron and slay that wyrm and its master, Wyrmcaller Vile! Even now, as we speak here, the frost wyrm may be on its way. However, if I’m reading these plans correctly, blowing the wyrmcaller’s horn on his platform, outside in the rear left area of Gjalerbron, will call Glacion back. When the creature lands, destroy it!
And Vikstone, please bring me the horn. We wouldn’t want it falling back into the wrong hands.”

Story Context
This is the payoff to the intelligence you delivered in Gjalerbron Attack Plans. You intercepted the Scourge’s offensive blueprint, and Mage-Lieutenant Malister has decoded it. His urgency is genuine: the frost wyrm could already be en route to Westguard Keep.
But Malister is more than just panicked. He is a tactician. He reads the plans and identifies the weakness: the Wyrmcaller’s Horn is what controls Glacion. Kill the handler, steal the horn, and you can summon the weapon back before it reaches your base and destroy it on your terms. It is a preemptive strike disguised as a defensive mission.
Malister’s reaction when you return captures genuine relief and something close to awe: “Once again you’ve saved Westguard Keep from certain doom. What a curious man you are. If only there were more of you.” The “once again” acknowledges that this is not the first time you have bailed out the keep, and the “if only there were more” reflects the reality of the Alliance’s thin presence in Northrend. They are undermanned, and the margin between survival and annihilation is measured in adventurers.
The Horde version carries a different tone. Celea Frozenmane at Camp Winterhoof is more practical about the situation: “Your instincts were right to bring this to me, but my wind riders cannot fight a dragon.” The taunka do not have the arcane firepower to deal with a frost wyrm from the air. They need a ground solution. And her completion dialogue carries a note the Alliance version lacks: “You have saved Camp Winterhoof from certain doom, not that we’ll be staying here much longer.”
The taunka already know this outpost is temporary. They are nomads displaced by the Scourge. You did not save their home. You saved them enough time to keep moving.
Lore Note: Wyrmcaller Vile and the Vargul
Wyrmcaller Vile is classified as a vargul, a specific type of undead vrykul. The vargul are not elite Scourge soldiers. They are the rejects. In the vrykul hierarchy, warriors who prove themselves in the trial of ascension at Jotunheim in Icecrown are elevated to the Ymirjar, the Lich King’s elite warrior caste.
Those who fail are raised by the Val’kyr into a lesser form of undeath as vargul. They retain enough intelligence to resent their fate but not enough status to refuse orders. They are given the jobs the Lich King considers beneath his real soldiers.
Controlling a frost wyrm is apparently one of those jobs. The fact that a vargul is the one holding Glacion’s leash says something about how the Scourge allocates resources. The frost wyrm itself is a terrifyingly powerful weapon, but its handler is expendable.
The Lich King does not waste an Ymirjar on babysitting a dragon at a recruitment center. He gives the horn to an undead failure and tells him to point the weapon at the nearest enemy base when the time comes.
Players will encounter the vargul/Ymirjar distinction on a much larger scale in Icecrown, where the trials at Jotunheim and the elite forces at Ymirheim form a major quest hub.
At Gjalerbron, you are seeing the Scourge’s caste system: the frost wyrm gets the prestige, the Ymirjar get the glory, and the vargul get a horn and a platform.
Lore Note: Frost Wyrms in the Lich King’s Arsenal
Frost wyrms are reanimated dragon skeletons raised by Scourge necromancy and encased in ice. In Warcraft III, they were the Scourge’s ultimate air unit. Glacion at Gjalerbron is one of the earliest frost wyrms players encounter in Northrend, and its presence at what is essentially a vrykul awakening facility reveals how seriously Arthas takes the operation.
The frost wyrm pipeline escalates dramatically as players push deeper into Northrend. In Dragonblight, the Scourge raids Sindragosa’s Fall to harvest blue dragon bones for mass frost wyrm production. The Frostbrood are the elite results of this program.
And at the top of the chain is Sindragosa herself, the former consort of Malygos, killed 10,000 years ago and raised by Arthas personally as the most powerful frost wyrm ever created. She serves as the penultimate boss of Icecrown Citadel.
Glacion is a footnote in that larger story. But footnotes still kill people. If you had not intercepted those attack plans and climbed this platform, Westguard Keep would be rubble.

Vikstone's War JournalMalister had regained his composure, though his hands still trembled slightly as he studied the attack plans.

“You were right to bring this to me. You must venture to Gjalerbron and slay that wyrm and its master, Wyrmcaller Vile! Even now, as we speak here, the frost wyrm may be on its way.” He traced a finger across the parchment. “However, if I’m reading these plans correctly, blowing the wyrmcaller’s horn on his platform, outside in the rear left area of Gjalerbron, will call Glacion back. When the creature lands, destroy it! And please bring me the horn. We wouldn’t want it falling back into the wrong hands.”
The platform jutted from Gjalerbron’s cliffs, exposed to the wind and the moving shadow above. Wyrmcaller Vile stood at its center, robed in black, the horn hanging from his belt.
His first spell cratered the stone where I’d been standing. His second caught my shield, frost crawling across the metal. I kept moving, and the third spell died in his throat. He folded around the impact, and the follow-through put him down.
I blew the horn.
Glacion answered.
It came down with bones gleaming with rime, eye sockets burning with blue fire. The first pass of its breath turned the stone around me white with frost. I rolled clear, feeling my joints stiffen. It wheeled, came again, and the platform shuddered under the beat of its wings.
The third pass, it landed and decided to kill me on the ground.
Its jaws snapped shut on empty air as I drove beneath its skull, mace rising in an arc that caught the back of its head and neck, at the joint where jaw met spine. The wyrm screamed. I didn’t stop. Blow after blow, targeting the same spot, until the bone gave way entirely.
Those burning eyes flickered once, twice, then went dark.
I stood, breath ragged, frost coating my armor in a layer that burned where it touched skin.
Malister took the horn gingerly, wincing at its touch.
“Wow, that horn is cold! Once again you’ve saved Westguard Keep from certain doom. What a curious elf you are. If only there were more of you.”
South of Westguard somebody had left unstable ore scattered along the road to Steel Gate while the dwarves who mined it were behaving very strangely, so Danger! Explosives!
