Hereditary Evil Raiser Syndrome

Hereditary Evil Raiser Syndrome, or HER Syndrome, was a rare genetic condition. Resulting from Malice, the syndrome was characterized by malicious intent and a destructive personality. Experimented upon by Seth Twiright, the condition became a lasting presence in the Evillious region.

Early History
Resulting from Malice, the syndrome spread among the gods and their kin in the Second Period and the mass outbreak of HERs lead to the world's destruction. With a HER among the surviving 72 gods and kin, the HER was later sealed in Sin along with his fellow twin gods and five kin around BT 528. He later escaped and incarnated in the third world the gods created as a human: Seth Twiright.

Seth's Experiments
Starting around the BT 020s, Seth Twiright developed ghoul children to increase the number of HERs, creating clones, Pale Noël and Kiril. Once he developed another method via seeds of malice, Seth created numerous new ghoul children over the years, causing a surge in HERs rampaging throughout the Magic Kingdom. As the HERs were identified, the Leviantan government attempted to root out the evil raisers and were largely unsuccessful.

Seth later took over the second Project 'Ma' established to eliminate HERs and prevent Levianta's prophesied destruction. The scientist then implanted the ghoul child test subject, Meta Salmhofer, with seeds of malice, creating the human vessels for the twin gods, Hänsel and Gretel on December 27, EC 0. They later escaped from the royal institute and Seth continued experimenting in following projects. At some point, Seth began developing several objects for the purpose of becoming vessels of malice.

When the Levianta Catastrophe occurred in EC 013, virtually all HERs were wiped out in the explosion and resulting destruction caused by Levia-Behemo; at that time, the deceased HERs' seeds of malice were released into the air, causing an extremely low chance for any human to develop the syndrome. After the twin-headed dragon's body fell apart and descended into Held's Forest, its fragments fused with Hänsel and Gretel. Around the same time, Seth transferred one of the surviving ghoul children, Irina Clockworker, from her mortally injured body into a stuffed red cat before dying himself.

Vessels of Sin
In EC 014, Hänsel and Gretel their foster parents, Eve and Adam Moonlit, and split Eve's Original Sin into seven fragments. Using Seth and his fellow god kin as the demons along with Eve's soul, the twins created seven vessels of sin before releasing the malice vessels into the world. Irina then began collecting them to spread malice. In December of EC 135, Irina gave the Lust sword vessel to Cherubim and allowed "Duke Sateriasis Venomania" to contract with the Demon of Lust and propagate to increase the number of HERs.

The Duke successfully impregnated Maylis Beelzenia, Mikulia Greeonio, and Lukana Octo with children that could develop Hereditary Evil Raiser Syndrome. Mikulia's bloodline was later ended with the death of her son in EC 150. Hänsel and Gretel later reincarnated as Arte and Pollo around the EC 290s, becoming the loyal servants to Duke Banica Conchita, introducing the noble to the Demon of Gluttony and killing for her. They were later devoured by Banica around August of EC 325.

On January 14, EC 457, Prim Rogzé was born as a HER. The Queen later gave birth to another reincarnation of Gretel, Ney Marlon, on November 1, EC 482. Afterward, Prim collaborated with Irina to destroy the Kingdom of Lucifenia while allowing the mage to experiment on Ney and use her as Marlon's spy and assassin. Prim was later killed by Ney in EC 505; following Ney's death soon after, Gretel's soul was absorbed into the Glass of Conchita and returned to the new demon Banica's service.

On December 27, EC 595, Hänsel reincarnated as Lemy. Later adopted by Irina posing as "Julia Abelard", the boy became her assassin for the criminal organization Père Noël. After Lemy's final death on January 30, EC 611, Hänsel's soul was absorbed into the Glass of Conchita and returned to Banica's service. Following Irina's clash with Banica and Levia, her soul was fused with Levia's and Eve Moonlit's spirits, becoming the entity of Ma. The new HER then continued collecting the vessels.

Symptoms
A Hereditary Evil Raiser, or HER, is said to be at their core an incarnation of malice, "programmed" to destroy the gods and everything they've created; therefore, a HER's tendencies could include physical violence, human experimentation, destruction, and deceit. As a natural prerequisite, HERs typically attempt to increase their own kind and ensure the continuation of their "mission" to spread malice by any means necessary. They likewise take immense pleasure in performing their actions.

However, HERs could be unaware of their condition and live their lives under the assumption they are normal. Similarly, despite their predisposition toward malice, a HER could still feel guilt over their darker tendencies. As a result, HERs vary in personality and some could attempt to resist the above symptoms as much as possible. In a similar vein, a Hereditary Evil Raiser could hide their symptoms to deceive their peers. In some cases, a HER is also born with Dissociative Identity Disorder, segregating the symptoms of malice to one of the split personalities.

Causes
Originating from Malice, all Hereditary Evils Raisers were created from the same source. A human HER could also be developed by cloning the human's body, thereby copying their entire genetic and mental makeup. A HER could also be born by implanting the zygote with seeds of malice, causing them to develop the genes of malice naturally as the fetus grew and developed. Therefore, HERs could be artificially engineered en masse as with ghoul children.

Following the Levianta Catastrophe, the seeds of malice taken into the air created an environment for a human HER's natural birth. Under normal circumstances, the chance of a fetus being conceived with the HER gene was 1/65530. Similarly, the chance of a fetus with the HER gene surviving birth was 1/9999. As a result, the chance of someone being successfully born with the HER gene was 1/655234470. Despite this extremely low probability, the offspring of one or more parents with HER Syndrome exponentially increased the chances the child would inherit it the gene as well.

As a result, family bloodlines could carry over the gene via seeds of malice throughout generations, though the chances of any given descendant developing the syndrome decreased as the family's blood thinned out over the generations. Additionally, through the manipulation of the vessels of sin and their demons, the probability that the child of a contractor would inherit the HER gene also rose.

Treatment
Originally, those who developed Hereditary Evil Syndrome had no known cure to their condition. In order to suppress the symptoms, Adam and Marry-Go-Round drugs may be administered and, in more serious cases, Clockworker Medicine is given. Despite this, those affected can refuse taking the medication, making it difficult to properly treat them. Later on however, Leviantan priestesses developed a method to remove the genes of malice from HERs, effectively curing them of their condition.
