OH! I like this a lot! It has a strange quality to it, but it is good. The way you make the situation seem so dire and depressing, but the feel the story gives me tells me they will survive and pull through. It is really good.

This definitely feels like there should be more to it.
I liked the set up at the beginning, it seemed quite epic, and I loved the idea of having fairies in armour.

Lilith says ok a lot though, and I didn’t think that really went with the style of the rest of it, or the fact that she was in charge of an army.

There were some really good ideas in here though.

Did spot one typo:
looked down out of reflexes – should just be reflex.

Interesting. I liked the imagery near the start, and the dialoge was both military-formal and fantasy-spiritual, an interesting mix.

I like the cliffhanger ending, showing the expanse of what they'd have to fight, and the vague hopefulness of fighting back against the dead hordes.

But still, I think continuing on with it couldn't hurt at all.

This is nice for a one-shot. If you want to continue, it's your choice. Some of the names sound Chinese. Your prose is excellent; your description is balanced, and you've got a good story to tell. Well done, man.
