there was a cracking sound that was first felt in the bones

I am a very Zen person generally, so whenever I feel anxious or out-of-place, I try to figure out why. This is one of those places. I felt like I wasn't supposed to be here as the ice towers turned and folded above me, cracking and pulling apart into an azure-blue glow. Everything was moving all the time, and I felt seconds away from falling into a crevasse and getting stuck forever. It was beautiful, ephemeral, and I removed myself from the ripping as quickly as seemed natural.
