Did.. did so few know about arithmancy networks? Considering the numerous bobbing heads, that seemed to be the case. I wanted to release a sigh but kept it internally instead, these were supposed to be the leaders or at least voices of said leaders of the world. "Arithmancy can be layered and separated to allow personal networks to be used. It required a strong magical source, but works similar to computers in the non magical world." I pulled out my hand mirror and showed it to everyone. "For example, this hand mirror allows me to communicate with those on a personal network of hand mirrors. The same principle could be applied to the Crystal Teleportation System, but defeats the purpose of a free transportation system across the world."
