Geirrvif at Valhalas has challenged you to defeat Carnage.
Should you succeed, speak with Gjonner the Merciless overlooking the southern lip of Valhalas.
- Carnage Defeated
You've been successful up to this point, <name>, but what you must face to continue to battle within Valhalas is a gigantic horror beyond imagining.
I must warn you to turn away now. Carnage is a mountain of flesh constructed by the Lich King's most fiendish minds.
I do not see how you and your friends will defeat it. However, the choice is yours.
