Note: This quest chain was recently reinstated with Patch 3.3; it was previously unavailable after Varimathras' demise during [74] The Battle For The Undercity.
The order has come down, <class>. Sylvanas herself has requested that I send my most 'capable' agents back to the Undercity for a highly sensitive tactical operation.
Unfortunately, my most capable agents were killed over three years ago. In their stead I have a collection of brain dead riff-raff.
<Nathanos stares coldly at you.>
Travel to the Undercity at once and report to the Dark Lady. Do not embarrass me, <class>!
Completion
The Grand Crusader sits safely in the Scarlet Bastion while his forces pour into our lands, desecrate our structures and monuments and murder our people.
The time has come to deal with this pest. You will become the instrument of our reckoning.
