First of all, what is a " word tree"? The world tree which I'm assuming you're talking about is Bartleby, the oldest living thing in Wizard City. You've got to be a member to have access in there. Or, you could become friends with someone and if they're in the world tree, just teleport to them and you should be inside the world tree. Then, you see a spiral like door, and when you press " X ", you see the worlds you have access to. Ta-Da! You're inside the world tree!
you have to finish the quest in wizard city and you will get a quest from the headmaster to go to the world tree and go to krokotopia
You have to comeplete the world your in. After you complete it, you'll get a quest from Merle Ambrose. He gonna give you a quest to the next world.
