The introduction of the Circuitry Formation Runes to Landeau was something he had never experienced before. Because his Essence Race couldn't reveal themselves, Landeau hardly got any contact with the communication system. At most, he got a few communication badges from Essefy.
Yet, because he didn't understand them, that badge looked nothing but some foreign object. He couldn't figure out why and how it worked. The main reason is that the communication system opened the door to many other improvements.
Let's not forget that while Rean was still in the Dragon Race Territory and watching over the System Sect, he and the others created other types of circuitry formation machines. Within those machines, there were the ones that allowed the building of microcircuitry formation runes. They used the first version to create the next one and then the next one to create another.
And as always, any Golden Tickets and Stones are welcome. ;)
