Recently, my fortress has been attacked by a Forgotten Beast with the label of "Beware it's poisonous vapours!".
I set up a save, with view to scum if it manages to destroy my army. However, it was swiftly beaten down by two swordsdwarves, even before anyone else or their wardogs could turn up.
However, it was able to get off two directed poisonous breath attacks: One even before a blow was dealt.
I knew that something was going to happen to those two, and decided to wait and see what form the poison took before scumming.
With no visible wounds, my Swordsman-turned-Administrator walks straight into the hospital, and promptly rests.
I look at his wounds, and see nothing.
The other swordsman follows him in.
As well as another two dwarves who were very far from the combat.
This is when I start placing all my attention on these guys. Turns out they are spraying out miasma, despite not having any visible wounds.
Then suddenly, by chance, I Z'd on a dog. Both of it's eyes were rotten.
Went back to my other guy's thoughts screens. All have eye rot.
My chief medical examiner had surgery planned on one of them, but instead decided to climb into the bed next to them and have his eyes rot.
This is what convinced me that it is actually infectious.
It doesn't seem to have spread to my permanent hospital resident, however.
I'm simply wondering a few things.
How bad is dwarvern blindness?
Can I expect the disease to spread to the entire fort?
Will the rotten-eyed wake up without treatment, and will the rot spread to, say, the brain?
