"Thank you."

"Now to resume our tale of history... After the Voidgods had been dealt with, there was an explosion in the variety of lifeforms on Azeroth, and in particular intelligent lifeforms, due to all the Arcane magic that had been thrown around. Among these were the protodrakes, the ancestors of modern dragons. Now, the thing about protodrakes is that they don't suffer from old age. Unless they're killed, they just get bigger and stronger as they grow older. The Azeroth that was in the process of being shaped by the Titans was still dangerous, so most protodrakes didn't get that old before falling victim to natural hazards or other protodrakes. Most protodrakes that is, except for Galakrond."

"Is there an upper limit to how big and strong they can grow?"

"Galakrond, before he died, was more than seven hundred feet long, nose to tail."

"And he lived longest?"

"Of the protodrakes, yes. And while he was alive... He wreaked havoc. Destroying landscapes, killing other protodrakes, claiming whatever he wished. He survived to run from Titanic intervention at least once, and was clever enough to evade them for a very long time. He was brought down at last by an unlikely alliance- five young protodrakes, clutchmates who survived an attack by Galakrond on their nest, together with the help of one of the Watchers, a lieutenant of the Titans. A mighty battle of daring, courage, and clever trickery," the telling of which eats up a considerable amount of time and this margin is much too small to contain.

"...and Galakrond's bones can yet be seen, in fact, lying where they fell not too far to the west."

...It'd probably count as getting a bit too distracted to go over there now instead of bringing the Lich King down right away. Even if Zera can fly them, Ling really shouldn't tempt herself with a project. And the ancient bones probably aren't going anywhere. 

('Why avoid temptation?' a delightfully smug voice in her head asks. 'You're greedy for knowledge. Go take it.')

"But now we at last come to the crux of the story. For their deeds in defense of Azeroth, the five clutchmates were rewarded by the Titans and granted great power and the mandate of Azeroth's stewardship. The black one, Neltharion, was named Earth-warder, charged with defending and mainting the integrity of the planet and its geography. To the blue, Malygos, maintenance of the world's magic and defense against those who would misuse it. The green, Ysera, gained trust of the ecosystems and the Emerald Dream where a replica of the untamed wild sleeps. To Alexstrasza, the red, leadership of the flights and the sacred defense of all intelligent life, as the leader and organizer of the fight against Galakrond. And finally, the bronze, Nozdormu, was granted insight into time itself, so that the world would not fall from its destined trajectory. This great infusion of power catalyzed the change of the protodrakes into modern dragons, and the clutchmates became the Aspects of the five great dragonflights."

"And you're of the bronze flight?"

"I was."

"You aren't now?"

"The mandate of the bronze is to protect the timeline, to prune off failed branches and prevent outside interference. We were given the ability to move backward and forward through time at will, to better see the shape of what we are to defend. But in doing so, it is inevitable that we find other perspectives, other outcomes. Many that are worse, but some that are better. And within that vast array of possibility, we eventually find the one that makes us question why we devoted ourselves to the primary timeline at the expense of the others."

"I found my critical point and renounced my duty. I am bronze no longer, bound to one destiny. Now... I am infinite."

"Interesting..."

" - The timeline can branch?" 

"Every choice has the potential to change the path."

"But are there multiple timelines existing at once?"

"For a definition of at once that gets highly technical. They exist, I can get there."

"There's a problem one of my allies has that you might be able to help with directly, then."

"I'll make a note to see what I can do."

"Thanks - there were shenanigans with time magic causing a loop involved, and she wants to rescue the versions of her from the other loops."

"Loops, huh. Those can get tricky."

"Would it be a challenge you're up to?"

"Unless I find you tomorrow and say it ends in horrible tragedy, assume that I'm willing."

"Excellent. We'll be very grateful for your help."

"I'm sure you will be."

"And now I think I've kept you here long enough to avoid my past self, so any further conversation you wish will be only for the pleasure of it."

...Very reluctantly: "We do need to bring down the Lich King sooner rather than later..."

"I've no doubt we'll meet again in the future."
