If we are to destroy Deathwing, we will need the power of the Dragon Soul. To obtain the Dragon Soul, I would have to take you back to the Sundering, ten thousand years in the past... but that time passage is blocked to me.
The creature that blocks us from accessing this time passage is named Murozond. He must be slain, here, in this twisted future, before we can continue our plot to unmake Deathwing.
This is why you were brought here, <name>.
