Solomar isn’t a normal planet.
There isn’t a culture on Solomar or really any history to speak of. Unless you think being dropped from the thermosphere and scrapping by on a half-destroyed planet is culture, the only thing you can say about Solomar is that it is the worst kind of hell.
It’s the hell I grew up on, anyway.
If you think about it, we’re kind’ve stuck. There is no transportation off the planet. There’s no contact with the greater galaxy. Our nonexistent overlords in the Imperium see us nothing more as a side effect of Solomar’s use as an imperial dredge; a glorified penal colony and garbage dump that once was the subject of one of the Imperium's many enemies. Now it’s just where they drop the prisoners that aren’t the most dangerous felons in the galaxy. Your run of the mill criminals, idiots, and problems. People who haven’t pissed enough important people off. My great grandfather was a smuggler who got caught with hand is the proverbial cookie jar. His sentence? Play a game of survival on a planet with little-to-no infrastructure defined by a few centuries of the Imperium dumping people they didn’t want to imprison indefinitely or reprogram in their little rehabilitation programs. We’re a planet defined by grifters, anarchists, and vagabonds.
And that's not even describing the wildlife.
Basically, Solomar sucks and we've got no choice but to survive here; god knows nobody expects us to.
