This is a neat little submission. A little madness, nice tragedy, bit of a hostile planet scenario. Overall: Thought-provoking. I could see using this on a smaller scale as well, in a fantasy setting. Far Ocean, God-From-Beyond-the-Stars with complete control of it. Turns out it's just lonely, wants to babble at people, and thats why no one makes it past the Edge of the World Waters. Cool.
As the others said, I agree with the others.
Hulking magi-mutants frenzied by religon. Not bad. It's been done but that's not a problem. The thought of an entire month without sleep is horrifying, especially when combined with the thoughts of what kind of stimulents, magical, physical, and chemical, these Samites would have to employ to achieve that without killing the subject. Not bad at all.
Hm. A hammer that lays down an area of darkness. Interesting item, never would have thought to use a hammer for something like this. The story is decent as well, I love the idea of a prisoner miner busting into a secret chamber. That's good stuff. Why is all the text bold? No point deduction, but it's ugly and cramped (in my opinion). You also have 3 or 4 blank lines at the top of the page, why? Do some formatting, pretty it up. But, the all important content is still nice.
