Chromie has asked you to accompany Arthas in the Culling of Stratholme. You are to speak with her again after Mal'Ganis is defeated.
1x Mal'Ganis Defeated
The Infinite Dragonflight are not likely to give up so easily. I cannot be certain of what they're up to, but something tells me we haven't seen the last of them today.
In just a moment, Arthas will face a desperate dilemma, and make a momentous decision.
Don't lose focus now, [player]. I needn't remind you how much is at stake. I must call upon you to accompany the prince in his culling of Stratholme.
Arthas must make it through Stratholme alive and you must see to it that he defeats Mal'Ganis!
