Soul Spell: It infects young people and tests them every 4 years. Various rewards are given for the difficulty of the test and the success of the person.
Soul Color: Indicates the rarity of one's soul. The rarer the soul, the more useful the powers gained.
Blue-Red-Orange-Yellow-Purple
Soul Champion: A person who has successfully completed Synraith's test and gained new powers.
Soul Class: Soul Champions become more powerful by fulfilling certain conditions. As Soul Champions get stronger, their class changes.
There are 7 different classes.
Latent - Awakened - Ascending - Transcedent - Paragon - Celestial - Ethernal
Monsters have their own classes.
Decayed - Cursed - Malignant - Corrupted - Fallen - Void - Abbyssal
Synraith: The name of the trials that those chosen by Soul Spell must face.
Warbound Essence: A system of gaining power by killing monsters. When a monster is killed, it transfers some of its essence to the one who killed it. If more than one person makes a concerted effort to kill a monster, the monster essence is distributed among them in such a way that the most useful will gain more power.
If the warrior kills an equal or weaker monster, his powers are instantly added to his essence, and if he kills a stronger monster, his rewards are increased, but not all at once, as receiving these rewards at once would upset the balance of his soul.
A Soul Fracture occurs when a warrior grows disproportionately by destabilizing the balance of their soul. Soul Fracture causes the warrior's growth to be restricted and some abilities to become unbalanced (e.g. more essence than necessary, negative side effects).
Powerful enemies leave "Proof of Conquest" when they die. Warriors can use this evidence for the good of their Academy or for their own.
