Deep inside the bowels of the Undercity hides the assassin responsible for the deaths of Bolvar and our brave soldiers at the Wrathgate.
Varian has brought the full might of the Alliance with him to assist in the take down. Join him and Lady Proudmoore in the manhunt and earn your place among the greatest champions of the Alliance!
For too long have the Horde been left unchecked. We allowed their territories to prosper and in return for our generosity they plotted and planned our demise.
Peace? Useless... it's gotten us nowhere. We have lost some of our greatest heroes to "peace." Let us see what battle brings.
Return to Northrend, <name>. Conquer it for your king - FOR THE ALLIANCE!
Notes
Talk to Varian to start the event:
Reporting for duty, your majesty! Let the assault begin!
King Varian Wrynn yells: Hidden inside this defiled city is the wretch responsible for murdering our brothers and sisters at the Wrathgate! He must be brought to justice!
3 minutes:
King Varian Wrynn yells: Soon we march upon this cursed place and cleanse it of its evil taint!
2 minutes:
King Varian Wrynn yells: The hour of our redemption is close at hand! Prepare yourselves!
The manhunt begins:
King Varian Wrynn yells: The march upon the Undercity begins now! Be empowered by your King's strength! Follow me, heroes! FOR THE GLORY OF THE ALLIANCE!
Varian buffs all nearby allies with "Strength of Wrynn", adding 30,000 HP, and a 10k healing on damage taken buff.
King Varian Wrynn yells: Onward, brothers and sisters! Destiny awaits!
The party reaches the sewer entrance.
King Varian Wrynn says: Our descent into the depths of depravity begins! Be on guard! Jaina, lend us your strength!
Jaina casts "Improved Brilliance Aura", which regenerates more mana/rage/energy/RP that can possibly be used and a runspeed buff. At the bottom of the tunnel, the party stops as waves upon waves of enemies are unleashed.
King Varian Wrynn says: What is this?! Stand your ground! Do not give them an inch!
Eventually, Putress unleashes the Engorged Blight Worm, which has 5 million HP. After the worm is defeated...
King Varian Wrynn yells: Solders, fall in! Guard the halls!
King Varian Wrynn yells: Your aberrations are no match for the Alliance, Putress! We're coming for you!
Grand Apothecary Putress yells: This cannot be happening!
Grand Apothecary Putress yells: It will not end like this! I've worked too hard! So many years... I... I will consume more energy!
Grand Apothecary Putress yells: The power washes through me! I see... EVERTHING!
Grand Apothecary Putress yells: MORE SUFFERING AWAITS!
Putress joins the fight with a 7.4M HP pool. Let Varian tank him. He also throws blight barrels for 10k a tick as the failed experiments keep spawning, though not as quickly as before. Eventually he is defeated.
King Varian Wrynn yells: And justice is served!
Varian loots Putress's corpse.
King Varian Wrynn says: What say you now, Putress?
King Varian Wrynn says: Look around you, brothers and sisters. Open your eyes! Look at what they have done to our kingdom!
King Varian Wrynn says: How much longer will we allow these savages free reign in our world?
King Varian Wrynn says: I have seen the Horde's world. I have been inside their cities. Inside their minds...
King Varian Wrynn says: I know what evil lies in the hearts of orcs.
Thrall yells [Orcish]: Mog Osh'kazil gul'rok il mog Ro'th zaga maza TOV'OSH (The Undercity belongs to the Horde once more! LOK'TAR!)
King Varian Wrynn says: THRALL! HERE?
King Varian Wrynn says: ONWARD! We end this now!
Lady Jaina Proudmoore says: Varian, stop! I won't help you do this!
Jaina stays behind as the party moves on. Varian and the remainder of the party reach the throne room, where Thrall, Sylvanas and a host of Warsong Battleguards await.
King Varian Wrynn says: The orcs have a battle cry: LOK'TAR OGAR! It means "victory or death." Fitting...
King Varian Wrynn says: To the throne room!
The king and his group walks in.
King Varian Wrynn says: I was away for too long. My absence cost us the lives of some of our greatest heroes. Trash like you and this evil witch were allowed to roam free -- unchecked.
King Varian Wrynn says: The time has come to make things right. To disband your treacherous kingdom of murderers and thieves. Putress was the first strike. Many more will come.
King Varian Wrynn says: I've waited a long time for this, Thrall. For every time I was thrown into one of your damned arenas... for every time I killed a green-skinned aberration like you... I could only think of one thing.
King Varian Wrynn says: What our world could be without you and your twisted Horde... It ends now, Warchief.
King Varian Wrynn says: ATTACK! FOR STORMWIND! FOR BOLVAR! FOR THE ALLIANCE!
The fight is joined.
Lady Jaina Proudmoore yells: VARIAN, NO! STOP!
Lady Jaina Proudmoore incapacitates all units with a freeze spell.
Lady Jaina Proudmoore says: It did not have to be like this...
Lady Jaina Proudmoore teleports all Alliance forces back to Stormwind.
Tip: After Putress is killed, King Varian Wrynn runs off to the throne room and Lady Jaina Proudmoore stays behind. If you want to see the action, follow the king into the throne room (which is located on top of the Apothecary in case you get lost). If you do not, you'll just be standing around with the Lady for some minutes and are then suddenly transported back to Stormwind.
It seems that even if you hearth/port/etc during the 5 minute countdown, Varian still starts without you. You could leave him to it and do other things then come back. But it may be better to just do it with him, as it is faster and more safe in terms of completing the quest, not getting lost when you try to find him, etc. And of course, the quest is among the most epic in WoW.
Upon entering the fight between Varian, Thrall and Sylvanas, Sylvanas may say her Aggro dialogue but Thrall and Varian will never.
