Through the miracles of Google: There's a <a href="http://www.ee.surrey.ac.uk/Personal/R.Clarke/sema4/" target="_blank">famous chain of semaphore towers</a> between London and Portsmouth, spanning a total of 108 km with 15 towers. That works out to about 4-5 miles per tower. Other sources claim <a href="http://www.sil.si.edu/Exhibitions/Underwater-Web/uw-optic-02.htm" target="_blank">about 20 miles</a> between towers, a <a href="http://interconnected.org/home/2003_01_12_archive.shtml" target="_blank">network covering 4800 km with 556 stations</a> (5.6 miles/tower), <a href="http://www.questacon.edu.au/assets/pdf/Captains_Code_-_Semaphore_Flags.pdf" target="_blank">25 km apart</a> (15.5 miles), or <a href="http://library.thinkquest.org/26451/contents/other/semaphore.htm" target="_blank">5-10 miles apart</a>.The longer distances are made possible by the use of telescopes. Let's say a maximum of 5 miles without the use of a spyglass. That means that I would need at least 2-3 signal towers between Traders Roost and Mor's End (16 miles). That sounds like a bit much. Maybe I should invest in two MW spyglasses and skip the intervening towers...On the other hand, a signal fire at Traders Roost could probably be seen from Mor's End at night. We might even be able to send messages by covering the light from the fire with some sort of shutter / wooden board etc.Anyone know of any existing magical items that would provide some form of communication at these sort of medium-length distances?</blockquote>
