I hesitated at the doorway, or what one might consider close to a doorway. It had the typical archway with delicate motifs, the whisperwood doors polished to a near translucent sheen, and...nothing behind them. Well not nothing, rather it was the presence of something with the quality of nothingness. Mist.

Before me braids of gentle moisture clung to the air with tenacity, afraid that if they might let go they'd drop beneath world. I too was afraid, the floor was nothing more than near homogenous miasma that ensorcelled the hallway. But fortune favors the winged.

I leapt, giving myself not a spare moment to contemplate an unknowable fate. I landed, harder than I might have feared, but softer than I would have liked. I sunk, into the hazy floor, my weight was in league with the tricksters mist and I was powerless to stop them. I flapped and flailed my arms in hopes of grabbing anything tangible, but those too were swallowed.

I found no purchase on gravity or direction and spun sluggishly through the air. The humidity permeated everything in this place, swallowing up any last remnant of space. Then my body erupted with alarm, my hopes realized by a hard slam into something solid. I pushed up my head to view my savior.

The room was titanic, the mist just thin enough to give the impression of boundless extents. The constant pitter-patter of rain playing the most complex symphonies I had ever heard. The stone I found myself on was one of nameless ranks extending in either direction forever into the mist. Beneath the rocks sat a pristine pond extending away constantly dancing to the droplets disturbing its shallow placidity. 

I picked a direction, what else was there to do? Fly through the roof? I had to use what was afforded me, my legs. It may have been minutes or hours leaping from one flagstone to the next. My feet were sore from each impact, a fact I did not take for granted. But something had changed, the sound of rain was faint in my ears and memory and so was the feel of stone.

I flinched when I saw my feet wrapped in velvety clouds. Like sediment kicked up in the river the mist twisted through the clear air lazily with each step. A breads width apart on either side the walls and even ceiling were made of the same writhing solid mist. One more step and the atmosphere had shifted once more. Though my senses couldn't comprehend it I knew in my core that I stood atop an immeasurable peak. The Mist formed a universe worth of space around me with the mist forming its boundaries, infinitely close and distant all at once.

I closed my eyes and took a long, deliberate breath before falling. There would be no ground this time to break my reverie, only endless mist in an empty sky.
