Glorazia

 Glorazia is a virus native to the habitable moon of Uingffh. It is a very erratic and dangerous virus due to not having any definite symptoms - they vary wildly between individuals and can range from no symptoms at all to total organ failure. This makes it very infective and easily-transmissible. Tabulons (the native sentient species of Uingffh) are the main host of Glorazia, but any species of fauna can contract the virus, which spreads through close contact or eating infected food or water.

In the year 0024 SC (2074 on Earth), a major outbreak of a strain of Glorazia called Glorazia-24 occurred which caused nearly 2 billion deaths, nearly a fifth of Uingffh's population, and infected over half of all individuals on Uingffh. It was so severe and unpredictable that it spread to numerous other planets and moons as well, including Earth. Furthermore, Uingffh itself was experiencing multiple other disasters at once including an asteroid impact and hyperactive tropical cyclone seasons. These combined with Glorazia-24 caused a mass extinction event on Uingffh that eliminated 25% of all species.

Though the Glorazia-24 outbreak is the most well-known, other outbreaks of Glorazia occurred during the years 1846 and 1529 through the strains Glorazia-46BH and Glorazia-29BH respectively. However, both strains were not as severe as the 0024 SC strain and were quickly contained.
