The journey from the Endora Kingdom to the Dream Kingdom took over four months.
On the way there, Seth spent the entire time teaching Meg destruction theory. When they reached the plains at Dream’s entrance, Seth had already used almost all the energy left in his piece of divinity to create a fifth shell destruction source inside her body.
The source was quite unstable, but he managed to keep it under control due to the piece of divinity tethered to his will.
Stephen was bored out of his mind the entire way since, despite having to travel with a lovely girl, she kept ignoring all of his tried to make conversation the whole way. Eventually, he gave up and spent all his energy taking her there as fast as he could.
With them arriving at a giant mountain on the Dream Kingdom’s western coast almost five months later, Meg said to Stephen: “This is far enough. I appreciate your help getting me here, and you are free to leave now.”
