I believe the quest is number 12 or 13. I don't know for sure because my save got corrupted and i can no longer open it. I do know it is one of if not the final quest for Larklast. It was given by the priestess you get for killing the evil god.
There was no Quest 7, I still want to know about it and it was definitely quest 13 that won't work. It was given by Chryseis, the priestess on the dead god of Larkast
thinking about starting over b/c my save got corrupted and I can't get to the third town anymore, but I think I'll wait until they put more work into it.
