The scarabs of Tanaris have very hard shells! Hard enough to use as a building material for lots of things. So many things! In fact, those shells are so useful... the scarabs were hunted all to near extinction! I know where there are more scarabs, and if you promise to bring me their shells then I'll tell you where they are. Promise? Ok, the scarabs have a colony in Zul'Farrak. I guess the trolls don't hunt them for their shells. But you can! Go to Zul'Farrak and get me uncracked shells!
