- "The Rakghoul outbreak will be catastrophic, billions will be infected."
- ―A Republic informant
The Rakghoul Plague is a horrid disease that transforms anyone who is infected into a Rakghoul. A serum for the insidious disease was discovered by Republic scientists three hundred years before the events of The Old Republic. The serum might not have survived the bombardment by Darth Malak.
During the Cold War, the virus spread among several worlds in the Tion Hegemony. After the annihilation of all civilized life on the world of Kaon, both the Galactic Republic and the Sith Empire sent parties to locate the source of the virus, to rescue their stranded people and to forge an alliance with the Tion Hegemony.
There is an outbreak of Rakghoul plague on Alderaan. All those strong enough to combat the creatures are ordered to visit the planet and kill any infected beings. All civilians are advised to stay away from the planet. If the disease spreads off-world, the Empire will begin full-scale bombardment of Alderaan.
