1) click on the RPG link at the top
2) make a name and profile
3) go to character and after the thing that says last seen disney castle-grand hall click it
4) talk to mini and get the warp sphere thing
5) go to the gigas hall and get a sword and armor and maybe potions
6) go back to the grand hall and go to the malus hall and talk to donald adn ask about the heartless and go to the cellar and fight heartless
7) once you get a gate pass go back upstairs adn into the grand hall again, then go to the south gate and talk to the NPC there and say i have a gate pass adn you can get to traverse town from there
i sugest that you fight alot and get to atleast lv2 before you go to traverse town
also you should find someone who would be willing to train you
