Beaconed border

The beaconed border is a stretch of land which makes up the border of The Northern Lands and The Eastern Lands,every two miles there is a tower which can communicate using a system of coded bell rings.The final tower in this chain is connected by a wire to a bell in Bragdon 'Huil allowing almost instant contact,this system is used in emergencies to warn the capital of advancing armies but also more routinely to ask permission for someone to cross the border.In order to pass from the eastern lands into the northern lands your party must proceed to one of the signal towers and state your purpose,you must then wait until a reply comes back from Bragdon 'Huil which will either be a rejection or an approval.
In order to maintain the security of the system the bell code is changed slightly every week to prevent the public from listening in on the messages.
