The Price for Freedom

For everyone stuck on the mysterious Empress' airship, whether they're aligned with her or not, they haven't tasted true freedom in months or even years. In a post-apocalyptic world, nobody is safe, not even the top crew members. Even if most of them could leave, their worlds are destroyed beyond living. 
 
Humans, monsters, animals and everything else in between are getting restless as rumors of a revolution linger in the air. A ragtag group of 13 rebelling crew members and prisoners barely escape with their lives. Some of them want revenge on the flawed system that broke them, while others want to go back to their hero roots and save the world. There's just one problem. Most of the heroes are shells of their former selves. On top of that, the rebelling crew members don't know how to be heroes.
 
Regardless, there is one thing everyone has in common, heroes and villains alike. The fear of their newfound freedom being ripped away from their very eyes.
 
The price for freedom is a strong, yet terrifying thing. Some will even kill just to keep their freedom. Bloodshed and death is very common in this dark world. How far are you willing to go to keep your freedom?
