The growth in communication crystals being made and sent around the kingdoms was one of the best things from the new Genesis alliance. Not only because they were a shared secret production method from various races coming together, but also because they had sped many things up.
Various merchants used it to be able to communicate with their merchant caravans as they traveled through the wilderness. Others used it so that they could send out guards to different positions that needed assistance with crime happening at that moment.
The usefulness had outshined everything that could be said about how rare and how hard they were to use before Genesis had come together. They had been improved to be used more times in a row without breaking. Be able to communicate more clearly using them. And furthermore, just in general numbers.
