From your perspective then, orbital defenses are pointless?
I see you are trying to tear apart the usefulness of static defenses but... to be honest I haven't invested the time or effort into researching FTL comms or drives or any of that. I just took the idea of a networked superfortress spanning the entire orbit of a planet and ran.
I'd slightly accelerate the growth of the flower; also, take into account that a few hours after death, the blood in the body is no longer fluid - hence, thye could us some anticoagulant and preservant (and thus be useful for alchemical blood preservation, too).
Other than these minor issues, a neat piece I might adapt and adopt :)
A hauntingly beautiful flower. I would love to see more on the magical, alchemical, or necromatic uses for such a flower, but that would really be like adding icing to an already superb submission. The reproductive cycle is still a little implausible to my mind -- it would make more sense for the flowers to offer something that attracts the ravens & crows back to the battlefield, so that the seeds may be deposited directly and have a much better chance of success. Other than that, well done!
A good, solid location to use for a lowbie adventure or two, though not a brilliant one. Aside from the singing noise (which I really liked), the mine doesn't really strike me as an interesting or unusual location, which is probably why it feels like something is missing here. The dangers you included are helpful and logical -- just not horribly original.
It's hard to think of new plot hooks that revolve around a mine, but it would be nice to see a few here. It would give us a better understanding of your vision for the place. Adding in some NPCs, terrain hazards and other unique features would also help to spice it up.
