Beginning Commentary: And now, a passage written by yours truly.
Lore: Mana
Mana is that of energy: living beings are created from, infused with, and die after exhausting it.
Humans began wielding magical powers decades, perhaps even centuries after the Manaketes welcomed and accepted them onto the surface. It is similar to breathing fire, as they would instruct.
This breathing of fire, along with taming the very strike of lightning, harnessing the powers of the wind, and surviving off the coldest of winters, were spells under the category of anima. Normally, when Mages use anima magic, they use the element best suited to their personality. If they are calm and collected, they use Wind. If they are passionate, yet fierce, they use Fire. So on and so on.
Alongside anima, there is light and dark magic. As is in fairy tales of old, light magic heals the user along with others as dark magic revives the non-living. Light conquers darkness as darkness conquers anima. So then, why does anima conquer light? Would light not be required to see the creations that anima has produced? Alas, it is hard to tell.
It is also hard to tell as to why there are few traces of light and ice magic. Some believe that those practices perished when the Great Calamity occurred, wiping out nearly every Divine and Ice Dragon known to existence. Others believe that there exists a Magic Council that approves of which forms of mana are acceptable to use. There are those who believe light magic simply converted to basic healing, and then there are those who believe that ice magic will ruin the lives of future Dragons and wyverns everywhere. To each their own.
Harnessing the powers of mana, though, is dangerous. Mana is unstable even to this very day, and tends to become a parasite, feasting on the user's energy until there is no more, if not properly trained. Humans have combatted this by strengthening their mana links and training them immediately.
Mana links are what they sound like: connections between the human body and the source of mana it wields. Each body is given a mana link, but it is weak from birth. This is how humans can breathe, create fire, and react to when it is cold or struck by lightning. They can be awakened under any given circumstance, either tragic, life-threatening, or even down right hysterical like a sneeze.
For those who struggle to awaken and harness their mana, they result to artificial means: creating a new mana link. In order to do this, an experienced Mage must give the struggling beginner ink for which mana can reside in. This ink will be painted onto a certain body part and will stimulate the original mana link briefly. However, the magic used will be limited, as the mana is concentrated in that one body part and is not flowing through the whole body. This can also be quite dangerous, as the original mana link will malfunction. Malfunctions might include loss of breath, unnatural body temperatures, lack of energy (whether it be apathetic tiredness or no movement at all), or even death. Be careful with its use!
