This toxin, derived from the fairly common medicinal herb Jacobs Root, has a very subtle but possibly devastating effect. It severely impacts night-vision (not thermal or similar exotic vision types), essentially blinding most creatures after nightfall. Duration of the blindness is proportional to dosage. Even full moonlight is still terribly dark to the victim, and in anything less bright, it is pitch black.
The toxin has a faint, carrot-like flavor and is slightly bitter.
There are rumors that a preparation with permanent effects can be brewed, but requires much tedious effort and additional rare components. It is an effective means to destroy many criminal's livelihoods. Go to Comment
Your point about countermeasures is well made, and could help reduce it's impact. However a powerful nation could get around some of the measures by forging or stealing watermarked paper and then treating it.
The wax seals and Notary are an excellent countermeasure.
Regarding damage transferral, it was not stated explictly, but only minor alterations such as writing will transfer, otherwise the use as a 'backup' copy is not possible. So, I'd say physical damage (tearing, etc) do not transfer at all, and total destruction like burning will simply cause the other sheet to become somewhat scorched but readable. Go to Comment
An ideal companion item for a spy deep within an enemy is the use of a magical quill which writes illusionary text. In reality it writes a plain-text message which due to the paper not transmitting magic, comes through clear on the other side. If someone were to see the local copy, they would see the illusionary text which would appear as something unimportant.
Spells which accomplish the same task are also useful. Go to Comment
A lesser powered (No magic capturing) version of the Book of Transcription made with this type of paper would be even more powerful, being a 'bug' with unlimited range, though the book would be hideously expensive.
Eg. For a 100 page book with standard (8"x11" - yes I know that is not a medival standard) size pages, you are looking at expending the equivilent of 550lbs of gold to produce the necessary twin paper. This is not even touching the cost of making it into a book of transcription.
Anyone of power would be well advised to periodically checking their library for books radiating enchantment they are not expecting. Could provide much gainful employment for lesser wizards of a trustworthy sort :) Go to Comment
A very well detailed location, but there are a lot of references to people and events that are not linked and only mentioned. Some of these sound quite interesting and could use some elaboration or linkages to the posts to make these clear. Go to Comment
The descriptions of the branches seemed detailed and specific enough that I assumed they existed and that there was more to the story.
I was genuinely interested in seeing what, if any, other aspects of the sub and it's implied universe were in place. It was not clear to me that it was intended as a standalone sub not part of a larger world which had not yet been linked in. Go to Comment
