I just found the Chieftain's son and I just got the imp village.
1st question...I didn't finish search the entire are around the citadel before the little imp took me across the lava. Should I go back over there and search that whole area?
2nd question...Once I was in the imp village I decided to go the first battlefield. As soon as I got there I was teleporter near some abbey by a necromancer. He wanted me to find some crystals or something. Next thing I know I'm talking to a witch about some paladins. Anyway I pressed the enter battlefield button again and it took me out of there. How do I get back to, where I was, so I can solve that necromancer, paladins quest?
