Pool of Tears

I am interested in studying Azeroth's past and I'm wondering if you'd be willing to help? There is a nearby place of historical significance within the swamp that I would like for you to venture to. The Pool of Tears lies to the southeast. It is said that upon its shores and within its depths are buried artifacts of the Atal'ai troll civilization. But beware, it is guarded by Somnus, an ancient green dragon, and his dragonkin, as well as carnivorous fish in the pool itself!
