The art of Sorcery Array fell into the category of Illusions and was considered as a relatively powerful art. Those who wished to learn this skill had to be talented in both alchemy and magic arrays. This requirement alone had discouraged over 99% of all apprentices from attempting it.
In recent history, there were very few Illusionist apprentices in this region, which meant Sorcery Array users were very scarce.
But at the same time, those who did succeed in studying this art could easily benefit greatly.
Under the art of Illusion, there were two categories that were said to be able to create "world illusions"—the arts of Mirage and Sorcery Array.
A "world illusion" referred to certain illusions that contained a complete world inside. According to records, users of Mirage and Sorcery Array were the only ones who could do so.
