“This is exactly what I had feared.
Thalen Songweaver's notes on the mana bomb he devised to devastate Theramore were under guard in Dalaran. Few knew of this.
I argued they should be destroyed. But others argued if such a bomb was again created, we would need them to disarm it.
And now those notes are both the problem and the solution.
Thankfully, I have read these notes, adventurer. I will walk you through disarming the mana bomb.”
