I don't get this. Why is Grizzleheim the last world if you can get there at level 20? I mean, other worlds you need to be more than level 20 to get there. I think Grizzleheim should be the third world, Wizard City, Krokotopia, then Grizzleheim. Is it the newest world they made so far? I looked at https://www.wizard101.com/game/worlds/grizzleheim and there is no world after it.
