Children of Mana/Star Lake, Topple

It is highly recommended here that you go on a few sidequests, a lot are available at Dud Services, which (for a fee) will give you a task for you to return to an area you have already been. There are also Tess' and Jinn's sidequests to do, which give you levels, armours and money which is a good thing at these early stages in the game.
