Teros

When Cadance finally burst though the top surface of the clouds, it was with a tortured scream.  Her eyes were clenched shut and she thrashed wildly in the air, kicking and spinning as she tumbled through the air like a crumpled paper airplane.  She finally fell back down to the cloud surface, shrieking as she bounced harmlessly off its fluffy surface.

As soon as her wings splayed out against the cloud, she gasped.  Cadance's eyes opened in an instant, and she immediately swiveled her head around to check her right wing.  It was intact, healthy, and yet wrapped in a familiar bandage.  Cadance blinked in confusion, before finally shaking her head and—with a whimper—standing and beginning to wander in a random direction.

Her lilac gaze stuck on her hooves, she trekked across the seemingly endless surface of the clouds.  The horizon was hidden, the black sky merging seamlessly with the dark edges of the clouds to form an indistinct haze of nothing that Cadance walked slowly towards.  Her slouching pink form was lit by pale beams of moonlight stretching down like celestial spotlights.

Cadance did little to give attention to anything.  Her mind limped between growling shadowy beasts and groaning zombified ponies as her nostrils filled with the phantom stench of a hideous crimson liquid.  She winced with every hoofstep, her right wing dangling uselessly from an injury that wasn't there.

For hours she continued forward, forward, on a path into an unseen abyss.  Whenever she braved a glance at the horizon, her tired gaze was met with only blackness.  Eventually, she felt herself stumbling, tripping over her own hooves as exhaustion began to take hold.

Cadance fell to her knees.  Her head lifted, and she stared unblinking at the blackness.  It was there, in the darkness, she knew they were waiting for her.  In the darkness is where they would be reunited, where Cadance would see her face once more.

The princess began crawling.  Had anypony been watching, it would have been a pathetic sight to see Cadance lurch forward, grasp the cloud's surface in the crook of her hooves, and struggle to pull herself ahead.  The entirety of the sky stretched on forever, into empty horizons on all sides.

The night wore on, and Cadance limped, wandered and crawled her way across the black surface of the sky, until she finally collapsed without a sound.
