I am the King Under the Mountain, and I am the first to comment on this thread.
I really enjoyed this piece, and only partly because I'm currently on anticoagulants and therefore bruise like woah. Mostly, I enjoyed it for its tone. It's wonderful, dark, weird, rural, apocalyptic tone. Every word was perfectly placed. The transformities of the townsfolk - and the way they reacted - were beautifully, deliciously wrong.
Most of all, though, I liked the justice. Oh, give me justice. Give me hot, dark justice, smelling like coals and tasting like copper. Give me justice as it is meant to be: the innocent walking free, the guilty broken so profoundly that they are become innocent once more in their suffering, the punishment fitting the crime. Science fiction and fantasy can do happy endings, and they can do sad endings, but nobody does justice like horror.
