Magical Power

Magic is a mysterious energy that humans, elves and beastkins can use in the new world. In this world, dark knights utilize magic to strengthen their swordsmanship.

History
It is theorized by the Cult of Diablos that 10 millions years ago, the world of "The Eminence in Shadow" originally did not possess magic. That is until the realms collided, with one of these realms pouring magic into the world. The Dragons went extinct due to their inability to adapt to the magic while the humans, elves and beastkin thrived.

Capabilities
In the New World magic is used by enhancing physical strength speed and stamina, it is also used on swords. Magic is rarely used on other items. Magic can sometimes physically manifest itself depending on the users' skill, giving off colors and other visual depictions. People who can do this can create Special Techniques, what kind of power they possessed depends on the one who creates the Special Technique

Weaknesses
Constant abuse of magic would result in magical overload in which the users suffer horrendous mutations unless they find a way to control their magic.
