most of my quest now want me to fight monsters in the first three levels on ekbatan, and I don't know how to complete these quest since there all in the city. what am I missing?
You get the quests in the city but must go into the dungeon to complete them.
If you don't like the quests you were given, you can always decline them.

The old one has been converted to an active archive where you need Admin intervention to get registered. The newer forum, under "Our Forum" on the main website navigation bar, still requires manual acceptance as a method of keeping Spam down.
