You both step out of the vortex and find yourself standing on the moon, strangely, and more strangely, you can both breath. The raft is gone. 

The girl looks at you, and says, "Welcome to the moon.  I'm sorry I had to trick you. But he needs you. I needed to use this quantum vortex transport device to get you here. " It turns out to be a quantum vortex transport device. "This wasn't a raft and staff at all. What you saw wasn't actually a raft, but a tear in the space time continuum."

You might be able to breath, but you are cold. You are not dressed correctly for this atmosphere. You have on a long sleeve shirt and pants, but they are loose, and you could do with a coat. 

The stars above you feel condensed, and even at this distance, strangely claustrophobic. The universe above you is far, but it feels like you could grab it by reaching up. 

The moon is gray and seemingly lifeless, but at closer look, it isn't.

"Follow me into the castle," She says.

The castle looks forbidding, and you really feel uncomfortable walking into a place you don't understand.
