Granted, but as soon you take your first step, Oz collapses, burns to the ground, get flooded, get sucked up in a black hole, and vanishes. Then you get transported to a journey around the world crashing into every mountain in the way, including Mt. Everest, K2, Kilimanjaro, Elbrus, Mont Blanc, Kebnekaise, Mount Olympus, Denali aka Mt. McKinley, Erebos, and finally you get stranded on Olympus Mons.
