Richter's Syndrome
Richter's Syndrome was a contagious and fatal disease. It could become airborne or could be passed through contact.
The first symptoms are cramps, fatigue, fever. This is followed by excruciating agony. They say it’s like being boiled alive due too every nerve cell in the body will be screaming out in agony. It’s not unusual for victims to beg for death. This is followed by an uncontrollable, primal fury and eventually death. (AUDIO: Cobwebs)
The virus also mutates that any ordinary vaccine is ineffective against it. The cure for Richter's Syndrome was created by Nyssa and Adric Traken who adapted a vaccine that Nyssa had created with data for how the virus mutates calculated by Adric over 25 years. (AUDIO: Prisoners of Fate)
