From Village go left up corner, go right, go all the way up past camp of enemy and fight enemies, You will get note named "Note from Zaratras?" something like that, sorry if I mistaken the name. Read note go back to village and talk to Gajah. Later in Village is building (look picture) go there and talk to Guy in right up corner. You will start mission and you will have to defeat boss, when you beat it and after talk with Gajah just come to Gajah house door and game will ask if you are sure you want to go to Act 2. I think that's everything, I was writting that from memory but I don't think I missed anything. Good luck
