Im excited to find out more regarding the ashbringer... also, Im still curious about the whole nerubian/qiraji situation. I wanna know more regarding the "dark master" (C'thun in the case of the ones in Ahn'Quiraj, still curious regarding other old gods or wtf c'thun is) and how the hell did both empires evolve in such different ways.
for those who are lore ignorant, allow me to enlighten you:
The nerubians and the qiraji are related. WAY before the great sundering, the war of the ancients and way before night elves existed, a race of insectoids ruled most of western kalimdor (what is known to us today as kalimdor, before it was a single huge continent with the same name, if you wanna know more, go read about the great sundering) this empire was known as the Qiraji empire, they were supported by a dark power (an old god). Back in the day, there was only one other Empire big enough to fight them. For all those who guessed nightelves, taurens or earthen, you are all wrong and should jump off a cliff. The answer is: TROLLS!. believe it or not, they are one of the most ancient races in Azeroth. Anyhow, the then mighty empire, known as the Gurubashi-Amani Empire (hint hint lets see who's a bright cookie) stood up against them and waged war for thousands of years. Eventually, they were able to "Sunder" the Qiraji empire into the Northern Empire and Southern Empire (Nerubians and Qiraji respectively).
Now the question remains, how did two completly separated empires, one at the very top of the world, and one at the very bottom, created similar technologies (destroyers, obsidian creatures, etc) and evolve to look so different one from the other?
