Name: Rattus Conversion Plague
Species: Norvegicus pestis-Y.R (A)
Rarity: Currently 25 - 50 subjects in experiments
Behavior: The Rattus Conversion Plague behaves almost identically to the bubonic plague that is half of it's genetic parent (the other half being Immortal Lab Rat subjects). The primary difference is that the characteristic buboes of the plague serve as incubators that then give 'birth' to rats, typically coinciding with the psychical 'death' of the host. The mind of the host is then transferred across any and all rats that were bred in the host's body. Although these rats appear sterile, and cannot bred (or simply do not wish to) breed with actual lab rats, they can breed amongst themselves.
The rats are slightly smaller than normal mice, and appear just as easy to kill. However their bodies are covered in Norvegicus pestis-Y.R (B) and their saliva carries Norvegicus pestis-Y.R (C).
Location(s): Exclusively found in Tombstone laboratories
Key Points:
- Incubation period of 2–6 days, when the rat cells are actively replicating.
- General malaise
- Fever
- Muscle aches
- Gangrene
- Headache and chills occur suddenly at the end of the incubation period
- Extreme weakness
- Swelling of lymph nodes resulting in buboes, the classic sign of bubonic plague.
- Death can occur in less than 2 weeks, with rats bursting from the buboes.
Appearance: The initial symptoms of the plague appear identical to the bubonic plauge right up to death. Post death, the affected will appear as a swarm of small rats, the were the color of the hosts' hair.
Name: Forced Microscopic Chimera Nest Virus
Species: Norvegicus pestis-Y.R (B)
Rarity: Tested on 78 subjects in highly controlled settings
Behavior: Virus occurs when handling the bodies of those deceased by Norvegicus pestis-Y.R (A), aggressively causing necrosis of the skin and removing all feeling to the external world, before the mutated chimeric cells will attach themselves to the blood cells of the host and grow. Subject will experience intense pain in the veins as the viral cells grow from microscopic, to the size of dwarf baby rats, draining the subject of their blood and eventually eating their way out of the host's body.
The microscopic chimeric rats breed incredibly fast, being able to go from one rat to several thousands, crowding all paths of blood in host's body in a matter of hours. When the veins or 'nest' is nearly full, the subject will be unable to bleed, and instead bloat with the rats and bleed out their waste. Experiments have yet to be tested on Immortals or Hollow.
Location(s): Exclusively found in Tombstone laboratories
Key Points:
- Severe necrosis
- Chills
- Coughing
- Chest pain
- Rapid breathing
- Dyspnea
- Hemoptysis
- Lethargy
- Hypotension
- Blindness
- Internal bleeding
- 100% mortality
Appearance: Initially starting as microscopic cells, invisible to the human eye-- these chimeric organisms will, if given the chance, grow to the size of anything from a flea to baby mice inside the veins of the host, before crawling out and swarming to search for more blood.
Name: Black Prions
Species: Norvegicus pestis-Y.R (C)
Rarity: Tested in several thousand criminals, volunteers, and mental health wards.
Behavior: Black Prions-- the result of combining rat neurons, the bubonic plague, and mad cow disease-- is perhaps the most interesting ailment created thus far on Tombstone in the Norvegicus pestis-Y.R A through D experiments. In that, it results, physically in creating what might be the next stage of human evolution. The mind of these subjects can slow down time from their own perspective, create fire and move objects with their minds, as well as a myriad of other side effects, such as no longer needing to eat due to developing sudden photosynthesis and reaching a peak of human physique that will increase physical life, theoretically, to several hundred years.
However, to reach these side effects, subjects must first be exposed to what has been dubbed 'Temporal Displacement Syndrome' or more commonly called, the 'stun' when injected with the Black Prions. From a bystander's viewpoint, the 'stun' lasts all of five seconds. From the subject's viewpoint, however, the 'stun' last more than several quadrillions of years.
The subject, when injected, will immediately experience a disconnection from their mind and body, what they experience as a second, will actually, from our perspective, be a single Planck time. Each Planck time, for them, will exponentially increase in time experienced, in complete mental isolation, 1 second will stretch on for trillions of years, as 1 second becomes several thousand hours becomes several million years and continued to exponentially stretch on, with each plank second ticking down. Subjects must experience 5 seconds, before returning to our frame of time, and by that point their minds have long been lost-- or perhaps truly found-- from several life times of several Universes in complete isolation. They all use their new powers to kill themselves in the first Plank time of the first second they return.
We have not calculated the exact length of time spent in isolation.
However, for reference, one second is approximately 10000000000000000000000000000000000000000000 Planck times.
Location(s): Exclusively found in Tombstone laboratories
Key Points:
- Those afflicted will experience perfect physical health and significantly increased lifespans, it is believed to increase their lives by upwards of 500 after the 'initial stun.' Theoretically, these individuals exposed to the 'initial stun' would develop near psychic powers, and would be able to 'slow' time from their own perspective
- Complete mental breakdown. The synapses of the brain become frayed, the myelin sheath is gone-- in 5 seconds, all outside influences are removed and you are faced with your true 'self'-- it is believed that exposing to human to absolute truth is what leads to the subsequent suicidal insanity. It is also theorized that knowing truth, even only one, any thinking being realizes that death is a logical alternative to existence for the sake of existence. This has not yet been cured.
- Near instantaneous suicide, typically committed by clawing at one's own face and throat.
- True enlightenment is reached. Becoming mentally older than the universe gives one complete and absolute clarity.

Name: Black Rat Synthesis
Species: Norvegicus pestis-Y.R (D)
Rarity: Currently the strain is only found in two beakers. Currently untested.
Behavior: Theoretically. This synthesis would give those afflicted with Rattus Conversion Plague to switch between being human and a swarm of rats. This was made using Immortal blood, it is currently untested.
