Terminology

Below are some of the most important terminologies used throughout Lyirnia.
  Sorcery: Used for any kind of magic, no matter where it comes from. Any who practice magic are called "sorcerers" and use sorcery.
  Demon: Pretty much any monster is often called a demon. Despite actual demons existing and whatnot, most people do not realize perfectly "natural" monsters are not the same, and often get called as such
  Blackstone: A term used for the strange black stone used in Aquilian ruins. No one actually knows where to get Blackstone, or how to make it, hence why only these ruins have the distinctive black coloring without using paint.
