Made at Hikaru's request.
Genesis Magic
Origin: Era Valley or nearby, was the magic of non-sage dragons. The dragons eventually developed into sages, meaning they could shift between sage and their true dragon forms at will, same as phoenix. These Dragon Sages used Genesis Magic, and a society developed from it.
Where to Find: Unobtainable... Kinda. Only a select few, today, have Genesis Magic, those select few being Hikaru, K2323, Kai, Koty, and Mokai (Akylos also has traces of it but not significant amounts). If one of these wills it to be, they can rid themselves entirely of Genesis Magic and give it to someone else. When they die, if they have not used a common Genesis spell to declare a heir receiver of their magic, it automatically goes to each of their children. Mokai also developed a spell which caused Genesis Magic to be present in grandchildren of his if they ever were born, instead of his child, fearing that her child would be targeted by those seeking the magic.
So, unless you're a child of one of the five/six above, or a close friend, don't expect even possibly getting Genesis Magic.
Price to Use: Heavy burdens on your spirit. A sort of inner-demon develops, something inside you which tells you to do bad things. Your moral can shift if you're not strong. Most people manage to suppress the 'inner-demon' through strong training in using the magic, but if you begin using Genesis too much and use it beyond the level of your training, this 'inner-demon' develops a body of its own, leaves your body, and basically is an evil-you with a sort of dark Genesis magic bent on destroying everything, especially you. These 'inner-demons' are called Negi and are present for all forms of magic, but Genesis is the most common time when a negi arises because all Genesis users have to deal with their inner-demons.

There's more to add, but I'm running short on time. This is good enough.
