This quest is not available in game.
Steal the four Mana Bomb Code Sheets and deliver them to Sergeant Chawni at Stonebreaker Camp in Terokkar Forest.
As I was saying, we've just received some further intel and there's a much larger problem at hand.
The blood elves are hard at work on the construction of a second bomb at Firewing Point. I cannot stress strongly enough the implications of them completing and using such a device on Stonebreaker Hold!
My scouts tell me that they are guarding the codes to the device in the four smaller buildings ringing the central courtyard. Get in there and retrieve those codes before it's too late!
