You're more than welcome to be mischievous or even down right evil at times if you want to be, though I warn you that your actions will have consequences if and once caught. For example if you want to be a bully, don't be shocked if you find another student shooting a fireball back at you in retaliation. If you sneak into areas you aren't allowed to be, you may draw the attention of a teacher. If you do something truly unwise such as attack a grand master, you may find your new life as a toad a little less than agreeable.

So no you don't have to be good by any means, but you do have to prepare to face the consequences of your actions. What fun would a story be with no conflict, after all?
