The True Beginning (5)
External Carving is a process of completing one's Magic Circle while materializing it to the world. This method requires the help of one's other Magic Circles to complete the Magic Circle one wants to finish.
This method was the fastest method any Mage could choose to Carve their Magic Circles. However, if a Mage missed even one step, the Carving process would fail and they would be forced to forfeit the Magic Circle they had been Carving.
Due to this reason, Mage always opted to Carve their Magic Circle without projecting it. This method is called Internal Carving—the safest and most common way to complete one's Magic Circle.
Of course, everything has their plus and minus. Although the success rate of Internal Carving was higher than External Carving, it took a considerably longer time.
This is the reason why there were still some Mages who dare to attempt External Carving; they wanted to advance faster.
