I left the game for a little while and when I came back I didn't have a main quest. I used quest finder(only took me to side quest) and looked up the worlds quest online and tried to figure out where I was that way, but none of the npc would talk to me or I wouldn't have access to a area( chamber of the mind). I don't know what to do next. please help me.
You have to try to trace your steps. If you can't remember when you've been, look up the storyline quests and see each quest giver one by one until you find where you left off. This has happened to me on more than one wizard. If you do that and still can't figure it out, you can ask for help from W101.
