So you want to get off tortage so you can go get power leveled or whatever. There is a way that most people dont know about.
1) Go to the way point 1143, 819
2) Right click the little poster on the back of the building
3) Follow the quest it gives you
4) Your off the island much earlier then with the "normal" exit quest
The developers must have included it for those of us that make multiple characters and dont want to go through those long quests many times. So there you have it get out of jail early
Enjoy.
