A truly rich and detailed story. Here is an edited version with added inner thoughts to give more depth to the characters.
With the press of a button, a man and Xerxez vanished, plunging into another multiverse. Xerxez felt a jolt of shock. Such incredible energy... but it's just teleportation. He knew his physical body was back in his own world, drunk, asleep, and sprawled among bottles. But as he looked down, he saw nothing. His physical form was gone from the mortal realm, and now he was here, in this man's dimension, traversing a new multiverse.
