Engineering at the expert level breaks into two disciplines: gnome and goblin. Gnome engineering represents by far the superior of the two! It's about the construction of wonderful gadgets and devices that make life better!
<name>, read this manual. If you want to learn more on gnome engineering, then take that manual to Tinkmaster Overspark here in Ironforge. Remember - membership is permanent and prevents joining the other discipline, so make sure you are sure before finishing his task!
Ah, a young engineer interested in pursuing the one, true discipline of engineering! Well forgive my melodrama, friend. While our situation remains dire, it still is always a good day to see another engineer respond to the clarion call of true engineering!
