The Void is a dark, powerful and unstable energy that co-exists with the Aether to keep the world in harmony. The Void energy can be used, however the cost of doing so, varies from each individual and the quantity of energy they need. Mind, body and soul can be affected (independently or various at the same time) by this energy, getting eroded or achieving forbidden knowledge that leads to madness.

The Aether is a pure, easily manageable and stable energy that is easy to use, however it requires a high level of mastery to use at full potential. This energy has no side effects, but it's considered weak due to many users unable to unlock the true potential of the Aether. However, achieving this mastery has the risk of being self-aware to dangerous levels. While Void is usually focused on destruction and distorsion of reality, Aether is usually focused on healing, creation and being in harmony with the universe.

Sin has been existing since the first second the universe came to life. However, not everyone is able to obtain Markings of Sin. These markings appear on the sinner's body whenever they surpass a "limit" of the weight of the sins they can stand, this "limit" is specific to each person and is usually pretty high. However, only a few of these sinners have the "honour" of being those who would be refferred as the Seven Deadly Sins, since only them will have a single mark that will be their signature for the rest of their lifetime. All of them have unique shapes, but are usually located in similar places.

The descendants of these sinners have Heritage Marks of Sin, wich are not gained by surpassing certain limit. Instead, this markings are installed in the descendants, and start showing up as the inidividuals grow up. Unlike the Markings of Sin, these markings usually mix various sins, instead of having an individual marking in a different place for each sin.
