The answer is Neltharion.

Neltharion the Earth-Warder was one of the five dragons who the Pantheon empowered with immortality, in the hopes that they would protect the world from any interference. Neltharion was forever loyal to his queen, Alexstrasza the Life-Binder, and his friends and kinsmen, Ysera the Dreamer, Malygos the Spell-Weaver and Nozdormu the Timeless. Nelthation fought valiantly alongside his draconic brethren during the War of the Ancients and finally banished them to the Great Dark Beyond, hopefully forever.

Exactly where he went wrong is still uncertain. But soon, the creature that was once Neltharion became the evil, insidious force that became known to the mortal races of Azeroth as Deathwing.

The Death Aspect. One of the greatest evils ever to breath the air of Azeroth, Deathwing, or Xaxas, as the elves would call him, is the hellish embodiment of all things chaotic and evil.

Deathwing's career of treachery began long ago. Being one of the five Aspects, he asked the other four to "join" him in diverting some power into an artifact that would come to be known as the Demon Soul, telling them that it could be used to protect the world from the Legion when all the dragons had gone, but he did not transfer his power into it and so weakened the others considerably. The resulting war rendered his race all but extinct, and the Demon Soul was made untouchable to him.

During the Second War, Deathwing ensured that the orcs would come across the Demon Soul, and they used it to subjugate Alexstrasza, the Red Dragonqueen, and commandeer her progeny to their bidding.

Deathwing, too, pledged his loyalty to the Horde, and in return, Goblin alchemists placed adamantium armour over the entire and considerable frame of Deathwing, rendering him almost invincible.

After the war's end, Deathwing found solace at Blackrock Spire, where a clutch of renegade dragons were feeding on any humans who strayed too close to their lair. Ner'zhul suggested an alliance, and Deathwing agreed, taking his followers through the portal to roost on a mountainous island across the Devouring Sea from Zeth'kur. Deathwing was believed to be killed, but he instead was simply working to consolidate his power once more.

Disguising himself as a human - Lord Prestor - he infiltrated the politics of the Alliance, and seemed set up to take over the nation of Alterac and marry into the royal family of Lordaeron.

Meanwhile, he used his many pawns to maneuver the mage Rhonin, who his rival Korialstrasz had been using to attempt to free his lover Alexstrasza, into Grim Batol. Deathwing tried to frighten the Orcs into believing that the Humans were attacking, so that they would move Alexstrasza, and, more importantly, her eggs, north to Dun Algaz, leaving her open for attack and her eggs open to be stolen. Deathwing wished to hatch a fertile female dragon, with whom he could repopulate his dead race of Black Dragons.

His attack, however, failed, the Demon Soul was destroyed, and Deathwing was sent retreating with the four other Aspects on his heels. The few survivors of his dragonflight, believing him to be missing or dead, have made their homes in the Barrens of Kalimdor.

He teleports you near Camp Taurajo if you answer wrong.

As an interesting bit of history behind this quest, if you answered the question incorrectly, you would get a debuff called "Mark of Shame". This would mean that horde NPCs wouldn't talk to you for (I believe) half an hour.

The side effect of this was that you were able to attack horde NPCs. I know of at least one horde guild that got together and killed Thrall in this way.

Just in case they ask a different answer here are the different charrs in book (if you are too lazy)&nbsp Alexstraza: The ancient and powerfull queen of dragons.&nbsp Ysera: the dreamer mortal subconsious emerald dreaming etc.&nbsp Malygos: Spell weaver&nbsp Nozdormu: Master of time and timeless, bronze dragon.&nbsp NNeltharion:&nbsp earth-warden. protector of azeroth.&nbsp

Each time you do this quest, the question you get asked is randomly chosen out of four.

Therefore, the answer you need to give isn't the same for every person.

You have to read the book you got from the barrow den BEFORE you hand in the quest to the tauren dude, because then he takes it off you and you can no longer refer to it.
