Vampire

A Vampire is a Serenza that has been infected with Cosa-Raktazé, an affliction that causes a hypersensitivity to sunlight, heat, and fire of any sort, including sensitive eyes and skin, as well as internal systems. Their bodies also react very poorly to purified and refined metals, including Kaina-za, which can cause severe illness or even death. Most notoriously, the disease also causes the victims to crave blood and chi from uninfected Serenza, which often makes them pariahs from civilized society. It also gradually deteriorates all but the strongest wills and turns them into feral monsters that are (in the words of other vampires, even) "best put out of their misery".

While the affliction carries many drawbacks, it oddly enough also has perks such as heightened reflexes and reaction times, as well as an increase of strength and agility. Some vampires even gain the ability to conceal themselves with invisibility, although these abilities are less effective in the sun. While they are weak to fire and light under normal circumstances, the chi-infused elements used by elementalists will actually empower them because they can directly infuse the chi into their system and convert the energized elemental matter into further chi energy to bolster their own skills. As such, Fireformers and Lightformers do not have an advantage over vampires in combat.

History
While many people blame the Jalenga for creating vampirism, it was not actually their creation. Rather, in an attempt to eradicate two other diseases they had discovered (one of which caused hypersensitivity and the other of which caused a craving for meat and blood), vampirism was an unintended byproduct of a mutation caused by external stimuli. These individuals were indirectly responsible for the Jalenga to begin their work on the mutagen that would eventually lead to the creation of Zaderism.

While the Jalenga did eventually design a cure for vampirism, it was rare and the vampires themselves were elusive enough that administering it to them was difficult. Some leaders operated under the pretense of having the cure in order to draw vampires in out of the woodwork, only to slay them on sight. As such, the level of distrust between Vampires and other Serenza exacerbated instead. Similarly, as the Jalenga worked on their cure for vampirism, they also were successful at creating Zaderei. While these abnormal individuals had a slew of different traits from other Serenza, they were also immune to vampirism. the cure involved Zaderic blood as a result, but there were more steps and ingredients to the solvent that would cure the disease, all of which were lost to history after the Jalenga's disappearance.
