Elphaba bit her lower lip in worry as she looked up at Dejah. "There is a spell to travel to different worlds. However...they name of the world must be said in the same language. I have a few books on the language, but my greatest concern is that what if what I call my home and its actual name are two different worlds?" She answered truthfully. She rubbed her arm a bit absently. "I would be fine not going back to my home, but I am scared to travel to another world. One that might be more hostile than your world."
