Salvation came with the arrival of a group of heroes who, according to Deckard Cain, had slain Baal's brothers, Mephisto and Diablo. Larzuk was skeptical, but directed the heroes to deal with Shenk the Overseer, a demon who Baal had left in command of the siege of Harrogath while he scaled Mount Arreat. The heroes succeeded, and Larzuk apologised for underestimating them.
Next, the heroes were sent to rescue Qual-Kehk's men, who had been taken prisoners by the demons. The heroes again succeeded, and Larzuk admitted that he was beginning to find Cain's tales of their past heroism more and more believable.
The race to stop the last of the Prime Evils continued, as did the heroes' actions. Larzuk learned how their elder Nihlathak had betrayed them. He also learned how the heroes had been forced to defeat the mountain's Guardians, a deed for which they gained his enduring respect. Eventually, the heroes defeated Baal himself, but at the cost of the purity of the Worldstone, which had to be destroyed. Larzuk was eventually killed in the resulting explosion.
Just so you know...The gold you pay me doesn't line my pockets. Much of it goes to buy the raw metal I need to melt down for weapons and armor. The rest -- well, all I can spare -- goes to Malah and Qual-Kehk for other supplies.
As we speak, Harrogath is under siege by Baal's demons. Catapults rain death just outside the town walls.
Baal himself travels up the sacred mountain, having left in charge here one of his most vicious generals, Shenk the Overseer. A ruthless taskmaster, he lashes his own minions into suicidal frenzies on the battlefield.
If you wish to prove yourself to us, destroy the monster, Shenk, that commands those infernal catapults outside Harrogath. If you manage to do this, return to me.
Uh... Did I mention there were catapults?
What's the matter, hero? Questioning your fortitude? I know we are.
You're an even greater warrior than I expected... Sorry for underestimating you.
As a token of my appreciation, I will craft sockets into an item of your choosing, and from now on, you'll get the best price for all my wares.
I crafted the swords and armor for Qual-Kehk's men. They were like brothers to me. I can't imagine the pain they must be suffering.
Save them if you can!
As a kid, I used to play soldier among the barricades on the mountain. There's no easy way through that maze of walls.
Since your arrival, Cain has spoken of your deeds in the Southern Kingdoms, defeating both Mephisto and Diablo. At first, I scoffed at his tales, but I'm finding them more believable with every passing day.
Larzuk was young, passionate, and a "firebrand," who took pride in his ability to craft the finest instruments of war. According to Anya, Larzuk would have been married long ago if not for his work as a blacksmith. For his part (going by dialogue options), Larzuk appeared to be attracted to the Amazon hero, suggesting that after the siege, they travel to the Skovos Isles together.
Larzuk's ideas appeared to be well ahead of his time, or indeed, the technological level of Sanctuary as a whole. His suggestions to Qual-Kehk and Malah were basically those of cannons and hot air balloons respectively, while Nihlathak also suspiciously mentions to the Assassin that Larzuk claims to have avoided Red Fever by washing his hands before meals.
