Ceresfan
Ceres was just minding his business in the Asteroid Belt one day, when something completely unexpected invaded their Solar system, some sort of infection, and the road ahead wasn't looking so bright...
NOTE: This includes elements from The Moon Woke Up. Also, some writing style deliberately changes as the story progresses in order to address changes in Ceres as the story goes on.
No ships.
(WARNING: Character deaths are involved, there is twisting and turning when becoming infected)
There is also attempted suicide.
