naked on glacier

I kept moving forward, dashing ahead through a pair of house-sized grinders before they could crash together with me in the middle. I whipped to the diagonal for a couple of rows, and the air got colder and colder as I went ahead. I could stand at the heart of a cavern of ice deep within a glacier, naked and wet from the shower and not shiver, but this cold was beginning to get to me. My breath became a large plume, visible in the air, and the floating chips of ice gathered on my eyelashes, making me fear that if I blinked, they might freeze together.
On I went, going over a single smaller block like a hurdler, and the cold got deeper and deeper, and while the Winter Knight had nothing to fear from slipping on simple ice, the fine, powdery sleet coating the cavern floor from all the grinding impacts did not make things easy, even for me.
One hundred and eighty yards or so, and things went relatively well. Then I found out that I had, indeed, miscounted.
I ran for the place where the opening in the row of spinning, randomly slamming grinders should have been, and realized about a step before I got there that it wasn’t coming.
So I pointed my staff at the more battered-looking of the blocks in front of me, focused my will and shouted, “Forzare!”
Unseen force smashed into the block, sending it spinning wildly away from me. The block into which it had been about to smash went spinning after it, as if the two were attracted by mutual gravity. I followed in their wake, as they smashed into a couple of blocks in the next row, and ice shattered into a cloud of mist and flying chips. Something hit my stomach and something else hit my hand. A section of block came tumbling wildly toward me, and I bounded up into a rolling dive that took me a good six feet off the cavern floor, shouting, “Parkour!”
Then I was through the grinders and into the shelter of the archway.
The cold there was a living thing, something that abruptly doubled me over, my body beginning to shudder and tingle. It took everything I had to lift an arm, secure a hold on the lever with my bare fingers, and haul it steadily down.
There was a loud grinding sound, like ancient, ice-encrusted gears beginning to whir together, and an enormous thumping sound that reminded me of explosives going off at a safe distance. The horrible cold faded almost immediately to something merely Antarctic, and I sank to one knee and peered back the way I had come.
