Lycanthropy

Overview
The Lycha Virus, otherwise known as Lycanthropy, was created by the Mad God Lycha after being tricked by his older sister, Arai. It was created to manufacture the perfect beast in an effort to win a wager Arai had made to Lycha, who goaded her brother into creating the virus in an attempt to damage the Human population, and as such will only affect that race.

Symptoms
Upon infection via bodily fluid contact or direct injection of the virophages, Lycanthropy will take at least one full rotation of the lunar cycle to completely infect its host. Once the infection is complete, it begins to change the human into a bestial, mindless hunter that has many wolflike body features such as fur, sharper and longer teeth, thick hide, claws, a tail, around a two-foot increase in height, around 85-95lbs increase in weight, elongated snout, arms, legs and fingers.

Post-Cure
After Queen Mirah manufactured a cure for the Virus, those who had already been infected were only cured of their mental symptoms, their physical symptoms still remaining. These symptoms had changed their DNA, forcing the mutations to be passed on to any offspring, as well as limiting the infected to only being able to procreate with one another, instead of the host race. See: Werewolves.

While the Virus still exists to this day, it is curable and will no longer leave the infected individual with the physical symptoms post-cure.
