You find yourself in a stream.

Wet, crisp, and cold, the water rushes along the many stones and grains of sand and over your bare feet.

"HARK!" A voice materializes in your mind. "Welcome to my domain, stranger! Oh. Okay. There's no tower. There was supposed to be a tower. This is really awkward..."
There is, in fact, no tower in sight. As you look around, things materialize into view.

To the North, you can make out a cave that seems to glow with some faint blue light.

To the East, a dark cathedral with spires reaching out in vain for the clouds, with the faint sound of bells coming from inside.

To the West, following the stream, is an...ice floe? No idea how it got there, but the water around it has tiny patterns of ice on the surface

To the South, a small, humble tavern, well lit and well-attended, flowers painted on the wooden walls.

And finally, further South, is a path to take you back home - you can just straight up leave!

"Do enjoy your stay here!" says the voice as it fades into oblivion.
