Tales from Omega Station: Omnibus Edition

Omega Station, aka the Rock. A barren, airless asteroid on the outermost edge of the galaxy, home of the richest of the rich and the poorest of the poor. Dotted with commercial, military and residential domes, the outer surface is the place to live for those who can afford it or are lucky enough to work there.
But the vast majority of the Rock's residents don't live in the surface domes; instead, they have tunneled downwards, moving ever further towards its fiery heart. The upper levels are safe, comfortable, secure—or as secure as anyone can be on Omega Station. The lower levels, now; they are home to the detritus of a double dozen races and species, all living in uneasy juxtaposition, fighting, loving, eating—and being eaten.
The Rock's location in space, the last real port before exiting the galaxy, has made it a valuable commodity to many governments and private corporations, as has the addictive drug straz, which grows only in its recycling vats. Control has been taken and given in a hundred bloody battles over the years, but those who live in the lower levels—and further down, in the Depths—are often barely aware of whoever claims to be in charge.
No one, really, rules the Rock, whatever they may claim, however many weapons and warriors they throw against it.
For the Rock is eternal…and it has many stories...
