Paw, Claw, Beak, and Hoof

Narne's takeover of Crossroads was a catalyst for change among all 4 of the Corners. It forced the world and its people from a place of complacency to a place of action. The Eastern Corner with strong identity but little to no organization was the first to fall under the warlord's wiles. The Southeastern Coastal cities not only provided Narne with the means to achieve her goals of destroying Crossroads but have continued to pirate supplies from sea merchants and provide Narne with both the numbers and magical power she needs to continue her take over of the East. However, groups of people began to gather together to both save the numerous villagers and traveling clans of innocent Eastern Corner people from the horrible fates that would befall them as Narne's troops pushed further East towards the capital of Súiltine. With over have the Eastern Corner under Narne's in the present day, the outlook for the Eastern Corner is not good. However, there is a leader among them that has taken on the monstrous task of coordinating both the rescue operations and the fight to push Narne back. That leader is simply known throughout the 4 Corners as Fox.
In the Southern Corner, the dawn of industrialization has caused a deeper rift between the Nobility Class and the Working Class. The rich continue to get richer while preying on the poor. Over time, the dissatisfaction of the Working Class grew to the point of the people organizing a rebellion against their Noble oppressors. Led by a mysterious individual simply known as the Badger, the Unbound Uprising, or often call the Resistance has been working at coordinating efforts across the entire Southern Corner in order to bring about change and equality.
After considerable communicating through common contacts, both The Badger and The Fox made a realization. A decade of fighting Narne and of all the resources the Southern Corner working class has been forced to break their backs over, none of it has reached the front line- ever. If the nobility has been spending a decade lying over their contributions to the war effort, what else have they, and other Corners' governments, have been lying about?
And so, the Eastern Resistance and the Southern Uprising combined forces and then began to seek audiences with leaders of the other 2 Corners to create a further united front. It took considerable time, but at last, as of the current date, all 4 Corners have begun talks of uniting together to assist the Eastern Corner in the fight against Narne. Yet, communication is no easy task.
With the Southern nobility most likely allied with Narne and her armies, the chance of having magical communication intercepted is very high. Combined with the incredibly dangerous occupation that is using any magic in the Western Corner and the secretive nature of the Northern Corner's main leadership, there needed to be a code and a method to communicate. Thus the code of Paw, Claw, Beak, and Hoof was created. Its creation is credited primarily by Fox and their number one confident commonly referred to as Bear as a way of transferring messages between companies of fighters across the Eastern Corner. The dictionary and its versatility were altered when the other 3 Corners' Resistances were added into the fight.
The language combines the art of language metaphor, a form of communication unique to the Air Touched and Fey creatures native to the Western Corner, to hide messages within everyday communications along a collection of symbology and color-coding to designate who the communication is from and who it is intended for. To an outsider, the handwritten messages simply appear to be a blank piece of parchment. Yet, with a simple chemical reaction or a hint of magic, the words will be revealed to the intended recipient.
The communications are transported via couriers from the Privateer Guild. While it is no easy task for any resistance member to learn it, Paw, Claw, Beak, and Hoof makes the perfect way to get the word across with Narne or her allies none the wiser. In order to notify a recipient that they have a message, one in the know must simply look for the paw print, the claw marks, the beak impression, or the hoofprint on the courier container. This could be something as mundane as a map case or a book, or as elaborate as a magically locked treasure chest. The Courier will most likely have little to no knowledge of what the item could contain, simply that the buyer will or should know exactly what the item should cost in order to pick up their correspondence. The recipient looking to "pick up their mail" will have to say the phrase, pay the right price before the Courier will sell the message, and from the outside looking in nobody should ever know that it is something beyond that simple.
