- The Rim: you are hurtling at an indescribable speed around the edge of a howling, impenetrable darkness, the skin on your face pulling with the force - and you're drawing nearer to the event horizon with each orbit.
Shadow land: the shadows cast the reflections, not the other way around.
The sea of holes, or Holey Sea.
Flatland: a 2 dimensional space, moving through time. You have only length and area - not volume. A line that points at you is invisible.
The inside of an ENORMOUS sphere; every minute or so you fall through the empty center, oscillating like a weight on a spring.
The void: It's dark. You don't even know what you're standing on - when you bend down to touch the ground, there's nothing there.
The miniverse: you're floating in space, and you're about twice the size of that planet 20 paces thataway.
Planck's Indiscretion: the empty space between all matter is exaggerated to the point where all that can be observed are quanta connected across emptiness, you being one such quanta.
The Apocalypse: the sun dominates half the sky, the heat is unbearable, the noise of the storm is deafening, the grass is catching fire.
The Meta: you are on an immense flat surface. There are impassive mountain-sized titans observing you from over the horizon. In fact, there are exactly as many of these colossi as are at this gaming table, right now...
