The Missing Expedition

About a week ago, my research team and I were out exploring the western wilds of Bloodmyst when we were attacked by bloodthirsty spiders. The effect of the crystal contamination was clearly evident as these spiders were massive and extremely aggressive. I managed to escape but my team wasn't so lucky. We must not let the same fate befall others. Go west to the Amberweb Pass and destroy the spiders and their matriarch, Zarakh.
