To kill Unicorns, or Dark Unicorns? I could imagine Unicorn HUnters in the vien of Dragon Hunters that seek out and attempt to remove the dark blight that they have become. Interesting plot idea for pcs. Go to Comment
While that is a simple question it is not a real easy answer. They have been seen as mounts for powerful demons but whether it is a broken and tamed thing or a power/ respect thing is totally unknown. No good person will be able to ride them regardless. Go to Comment
I would like to think that an iconically good creature such as a unicorn would not easily follow this path, even in the case of the violent death of their mate. A subset may fall into darkness, but I would not think all.
I have a liking large insects. I thought I had voted on this and commented as well, but I guess not.
The detailing of the poison works well for me. The rest of the write up bring the feel of a real animal to the post. We will have an insect/ spider/ crawlie thing scroll coming online soon, and this will be added to that.
