Paper Dragons are not truly living creatures. They are pieces of parchment enchanted by magic, and as such, are very vulnerable to fire. However, they behave almost like dragons. The only place where their behavior differs is breeding: paper dragons cannot breed.

Code is a very careful dragon and has learned much about remaining unseen as it goes about making its deliveries. All messages that it delivers are written upon its body in an invisible ink and written in a code that few know but many would like to. The messages are ones of critical importance and this has made it feel important but also very shy of other dragons. Always it has to be careful and even when nothing is written upon it, still it remains well away from others, usually staying in the vicinity of the General or other high ranking officials, ones that it knows will not have any reason to detain it and try to force it to reveal what it knows.
