These are all the side quests in the Ancarian regions of the game and the towns are listed in alphabetical order... all can be done in SP and most in MP. All the quests are listed by the location that you start them in.

how many quests in that region
* There are a few quests that I did not mark that require you to escort someone but they are short walks with little or NO monsters between so you should have no problems.
Huge thanks goes out to harper_6w5 for listing the Underworld only quests for me!
