I am writing something and I need help.
Basic premise:
A race is currently enslaved by aliens and have been relocated to a planet in a system near their masters.
They have a population of about one billion.
My problem is that, one, I don't know what the alien overlords do with their slaves, and two, I need the slaves to some how get their hands on military grade space ships and fight their way to their home planet.
There are other, mostly neutral factions in this universe, including an alien race at war with the overlords. I can see them helping the slaves, but I can't really imagine them just giving them a fleet of warships.
Please help me.
Simple:
The slaves crew the starships of their masters, and are usually kept in line with beatings and threats of genocide. They've never been able to rebel before, because there simply isn't a large enough concentration on each ship. But they have a big elaborate plan (you'll need to figure it out) to get enough of their people onto enough vessels to be able to effectively take them over all at once.
Bam, you have your fleet, your rebellion, and means to stage any number of other missions, perhaps to capture more resources in order to evacuate your people, etc. etc.
The plan: They subtly provoke a bigger, meaner race into attacking the masters, and so the masters crew the front-line warships almost exclusively with slaves because they know they'll be blasted first. When the battle comes, the slaves take their new ships and bug out, leaving the main force of masters-controlled ships to be wasted by the other guys.
Alternately, the slaves' new planet is a giant factory where starships are built, and the slaves are the builders. With very careful long-term planning, they manipulated schedules so that a great many ships will be space-worthy at the same time. Unfortunately, most of the ships they are using are un- or lightly-armed. They load up as many people as they can and embark on a campaign of capture and destruction.
Alternately, the slaves use their knowledge of advanced particle physics to whip up some really cool and destructive illusions, and send a pair of emissaries to the masters' leader to negotiate for their freedom.
