Well you'll definitely go into Azteca, and to get those 8 levels with the somewhat low xp the Avalon provides it would probably take anywhere from 7-12 days depending on your school and skill. A good storm can fly through worlds, while a bad one can get stuck on one thing for ages. While a good ice wizard probably won't get stuck on much, but will take longer to finish each enemy. It all depends on how good you are.
