Drop pretty good loot
There are not a huge amount of quests though and some, such as Enemy in the cheap Metin2 Yang and the campaign quest Kaidan Prisoner will take you into the nearby group only area of the Kaidan Mines. I suggest you not try to venture in here without at least a few friends because it is a pretty tough little spot. If you are looking to grind a little in this region, the Ancient Caryatids are a nice choice. They give decent experience, drop pretty good loot and respond quickly.
