Walkthrough

Zelig has analyzed the Onslaught Map from the previous quest and identified a cave the Scarlet Onslaught labeled “Frostmourne Cavern.”

His quest text: “They have labeled the cave as Frostmourne Cavern. Why the Scarlet Onslaught is interested by such things is unknown, but by the look of things, the area surrounding the cave is heavily guarded. Nonetheless, we must proceed!”

Getting to the Cavern

Travel north from Wintergarde Keep, then northwest toward Scarlet Point. The cave entrance is at approximately [74, 23]. The area around the entrance is guarded by Scarlet Onslaught forces.

You will pass through or near the Onslaught’s fortifications at Scarlet Point to reach it.

Inside the Cavern

Upon entering, you receive the buff “Haunting Memories: Surrounded by dark memories.” The cave is linear but not empty. Deathbringer Revenants patrol the path to the altar. Fight through them to reach the back of the cave.

At the rear of the cavern, you’ll find the Altar of Frost. Look carefully at the ground in front of the altar.

Three weapons lie abandoned in the snow: Light’s Vengeance (Arthas’s paladin warhammer) to the left, and a one-handed axe and battlehammer of dwarven make (presumably Muradin’s weapons) to the right. These are the real, physical weapons left behind when the vision you’re about to witness took place years ago.

Activating the Vision

Use Zelig’s Scrying Orb at the altar. The walls of the cavern shudder and shake. Ghostly images of Prince Arthas and Muradin Bronzebeard appear before the altar, along with an image of Frostmourne hovering above it.

The full dialogue plays out:

• Prince Arthas: “Behold, Muradin, our salvation, Frostmourne.”
• Muradin (kneeling to read the inscription): “Hold, lad. There’s an inscription on the dais. It’s a warning. It says, ‘Whomsoever takes up this blade shall wield power eternal. Just as the blade rends flesh, so must power scar the spirit.’ Oh, I should’ve known. The blade is cursed! Let’s get the hell out of here!”
• Prince Arthas: “I would gladly bear any curse to save my homeland.”
• Muradin: “Leave it be, Arthas. Forget this business and lead your men home.”
• Prince Arthas: “Damn the men! Nothing shall prevent me from having my revenge, old friend. Not even you.”
• Prince Arthas: “Now, I call out to the spirits of this place. I will give anything or pay any price, if only you will help me save my people.”
• The ice shatters. A shard strikes Muradin, who collapses. Arthas casts aside his hammer, claims Frostmourne, and runs toward the cave exit.
• After Arthas is gone: Muradin (rising, dazed): “O’ my head… Wh… Where am I?”
• Muradin: “Who… Who am I?”
• Muradin runs out of the cavern, leaving his weapons behind.

Do NOT follow Arthas when he runs toward the exit. This causes the quest to fail to complete. Stay at the altar. Quest completion triggers after Muradin’s final lines.

Arthas simply despawns before reaching the cave mouth. If you miss it, you can reuse the orb after the 1-minute cooldown.

Return to Zelig at Wintergarde Keep. His reaction is immediate: “Muradin lives? Could it be? I must notify King Bronzebeard at once! I need to consult the orb. There must be more information… somewhere!”

Tips

• Clear the Revenants first. The Deathbringer Revenants inside the cave can interrupt your experience and potentially kill you during the vision if you skip past them.
• The vision is a scrying recreation, not time travel. You’re watching an echo of past events through Zelig’s orb, not physically traveling back in time (unlike the Caverns of Time). The NPCs cannot see you. The actual abandoned weapons on the ground confirm that these events physically happened here.
• Horde players can watch too. You can watch an Alliance player trigger the cutscene. While Horde cannot do this quest, Frostmourne Cavern is worth visiting for any lore enthusiast.
• This quest rewards the highest reputation in the chain (+350, compared to the standard +250 for most chain quests), reflecting its importance as the finale.

Lore & Story Context

The Fall of Arthas Menethil

This quest recreates the pivotal moment from the Warcraft III: Reign of Chaos human campaign. Arthas had pursued the dreadlord Mal’Ganis to Northrend, consumed by his desire for vengeance after the Culling of Stratholme. Muradin Bronzebeard, already in Northrend with a dwarven expedition, told Arthas about a powerful runeblade rumored to be hidden in a cave.

Watch Arthas’s dialogue carefully. He begins by saying he would “bear any curse to save my homeland,” but when Muradin pleads with him to lead his men home, Arthas’s true nature reveals itself: “Damn the men! Nothing shall prevent me from having my revenge.”

This is no longer about saving anyone. It’s about vengeance.

Light’s Vengeance, the holy warhammer given to Arthas by Archbishop Alonsus Faol when he joined the Knights of the Silver Hand, lies on the ground where he threw it aside.

The symbolism is deliberate: Arthas didn’t just pick up a cursed sword. He discarded everything he was first.

Muradin’s Survival: Not a Retcon

In Warcraft III, the camera followed Arthas out of the cave. Players assumed Muradin was dead because Arthas assumed it. This quest reveals what happened next: Muradin woke up with complete amnesia.

Nothing in Warcraft III explicitly stated Muradin died. The original game simply never showed what happened after Arthas left.

The Frostborn dwarves of the Storm Peaks later found a wounded, amnesiac mountain dwarf wandering through Dragonblight in a blizzard, following a trail of blood-soaked snow.

When a massive jormungar attacked the party, the stranger transformed: his skin took on a stone-like texture, his hands crackled with lightning, and he smashed the beast’s head with a stormhammer.

The awed Frostborn named him Yorg Stormheart, a name reserved for heroes, and he eventually became their king.

Zelig’s Orchestration

This quest concludes a chain that Zelig set in motion by foreseeing the scrying orb’s significance five years before the player arrived.

The chain progression is remarkable: Zelig sent the player to find the orb (Imprints on the Past), the orb revealed the Forgotten Shore massacre (The Forgotten Tale, The Truth Shall Set Us Free), the freed ghosts’ gratitude led to Orik’s map discovery (What Secrets Men Hide), and the map revealed Frostmourne Cavern.

Every link was necessary. Zelig’s completion text confirms the payoff: he immediately pivots to notifying King Magni Bronzebeard that his brother may be alive.

Easter Eggs

• Warcraft III Audio: Multiple players note that the voice lines in this vision appear to use the original Warcraft III voice recordings, a deliberate nostalgic touch.
• Light’s Vengeance on the Ground: The physical hammer at the altar is not just a set piece. In Patch 3.3, it becomes a quest objective for the Shadowmourne legendary weapon chain (The Sacred and the Corrupt). Players must retrieve Light’s Vengeance from this exact location while defending against waves of ghouls the Lich King sends to stop them.
• Three Weapons, Three Stories: The abandoned weapons at the altar tell the complete story without a single word of dialogue. Arthas’s hammer on the left (paladin faith, discarded). Muradin’s axe and battlehammer on the right (friendship, forgotten). Frostmourne itself is gone, taken.

Cross-Expansion Connections

Muradin Bronzebeard’s Full Arc

• Storm Peaks (WotLK): The player quest chain at Frosthold reunites Muradin (as Yorg Stormheart) with his brothers Brann and Magni. His memories return. He vows to hunt down Arthas: “I’m goin’ after the boy. I’ll make’m answer for everything he’s done.”
• Icecrown Citadel (WotLK Patch 3.3): Muradin serves as a commander aboard The Skybreaker, the Alliance gunship. He directly participates in the assault on the Citadel that began with his “death” in this cave.
• Cataclysm: After Magni is petrified attempting to commune with the earth, Muradin returns to Ironforge as the Bronzebeard clan representative on the Council of Three Hammers.

Frostmourne’s Fate

• Halls of Reflection (WotLK Patch 3.3): Jaina Proudmoore (Alliance) or Sylvanas Windrunner (Horde) attempts to claim Frostmourne from an altar inside Icecrown Citadel. The attempt fails. The Lich King appears and pursues the party through the halls in the most terrifying 5-man encounter in WotLK.
• Icecrown Citadel (Final Encounter): Frostmourne kills the entire raid at 10% health. Tirion Fordring, empowered by the Ashbringer, shatters Frostmourne, releasing thousands of trapped souls, including King Terenas Menethil. The blade that began its corruption here is destroyed.
• Legion: Death Knights reforge the shards of Frostmourne into the Blades of the Fallen Prince, the Frost Death Knight artifact weapons.
• Shadowlands: The Jailer is revealed as the original architect behind both Frostmourne and the Helm of Domination.

Light’s Vengeance to Shadowmourne

• Icecrown Citadel (Patch 3.3): Darion Mograine of the Knights of the Ebon Blade sends players back to this very cave to retrieve Light’s Vengeance. He uses Arthas’s former weapon as a core component in forging Shadowmourne, a legendary axe designed to rival Frostmourne. This cave becomes a quest location twice in the same expansion.

Shadowmourne’s Sealed Chest contains items connecting back to characters central to this story: Arthas’s Training Sword (delivered to Muradin for Muradin’s Favor), Jaina’s Locket (delivered for a Dalaran teleport trinket), and Sylvanas’s Music Box (which summons banshees performing “Lament of the Highborne”).
