Hedron Towers allow the Hedron Network of the Kirinal Concordance Zone to be accessed outside of the Zone itself. The presence of Hedron Towers along with the railways are a sign of the expanding power and influence of the Concordance for Survival on the continent of Krosia and eventually around the world. The merchant princes responsible for them have amassed qute a bit of wealth for themselves.
I don't know that much about technology, but I do know that them towers let me watch my hedron dramas even when I'm traveling! I do question the wisdom of putting expensive hex crystals out in the wilderness! The tower owners have to lay out a lot of bilog to cover the costs of security! I hear lotsa stories about ne-er do wells who double dip by working as both security and as crystal rustlers and pirates!
Hedron towers started going up in the past few decades extending from the Kirinal Concordance Zone through the Sovranty of Lozar and now cover most of the Concordant Lands in western Krosia. They have allowed fast communication throughout those regions, not only between the rich and powerful, but between everyday people.
The Hedron Network allows people with Ident-a-hedrons to magically communicate with each other outside of line of sight. It further allows for communication from official Zone authorities to everyone carrying a hedron. Independent companies have also started broadcasting news, music, and simple images for everyone on the network.
With the combined magical and mental links from a third of the continent. We should just be glad that the flayers can't chew crystal.
The construction of hedron towers has led to a new type of crime, Hedron Hijacking. Each tower contains a hex crystal in it worth thousands of bilog in it. Hex crystal is very easy to resell, so raiders and thieves target the towers constantly, disrupting hedron network service for regions relying on those towers. The towers are usually built next to rail lines both for ease of access and to share security with the railroad owners.
A communications and entertainment network that transmits along the network of ident-a-hedrons carried by all sophonts in the Kirinal Concordance Zone.
