I am fairly sure this has been discussed before, but not in-depth on this forum. So I’ll ask, what would happen if a Flood outbreak occurred in the Star Wars galaxy? Would they be able to contain the infection, or would they be consumed, etc. What would happen? Answer can be any era (Republics, Empire, etc.), and any scenario.
Example Scenarios:
1. A backwater spaceport planet in the Outer Rim. At a local bar, the shady patrons are interrupted by a loud noise in the sky. They look towards it and find themselves looking at a strange dark violet/blue sphere. As the sphere disappears, a strange bulbous purple ship materializes, unlike any kind they’ve seen before. Emanating from the ship is an ominous trail of brown clouds. As the CCS Battlecruiser, Indulgence of Conviction, crashes onto the surface, some of the populace begin trekking toward the ship for a closer look. They should have evacuated immediately, for the entire planet was already endangered of being lost.
2. On Coruscant, an excavation team stumbles across an old container of suspicious dust. The container is accidently dropped and breaks, exposing the workers to the dust. Although they don’t feel 100%, they shrug it off and continue as normal. Little did they know, the situation was far worse than anyone could imagine, as that night, they began to undergo a horrible transformation.
I think that the Flood has a large edge in this situation, especially if it’s a surprise attack, as the Flood spreads fast through unprepared and unaware civilians. Especially if they begin on Coruscant, as the planet is full of spaceports, trillions of potential hosts, and plenty of other diseases, slums, and lowlifes, mostly ignored by the rest of the population, which would perfectly mask the disease until it’s too late. Other things to keep in mind are how powerful the Gravemind would become if the Flood were to infect a Jedi/Sith. Most critically, in the SW universe, faster-than-light crafts are common, cheap, extremely widely-owned, simple, and much faster than slipspace. This gives the Flood incredible, quick access to anywhere else in the Galaxy.
