I'd be looking for either a 1x1 partner or a co-GM for a small group RP. I tend to have one primary character and maybe some supporting characters, but I can do more. Let's get right into it.

The galaxy has already faced the apocalypse. Much of civilization had been destroyed in the war against an unknown force of horrors. Not some strange, interdimensional horrors that defy logic or reason, no. These horrors were familiar, these horrors were flesh and bone contorted and stretched together with machinery to become horrendous abominations of destruction and violence.

The horrors came, and at the final hour of the Terran people, the apocalypse vanished. None remain to remember why, or even to remember the threat, but fragments of the doom that came remain. Parts and pieces touched by the taint, whole machines just waiting to wake and begin the mindless slaughter yet again.

Amidst the peace, obtained by ancient powers in a wild gambit, hope had been given a form. A new kind of material, crystalized energy, had been left behind in the wake of disaster. The substance would come to be known as Aevon, and it would power the rise of Terrans back into space and beyond.

A message left with the crystal would drive them. The apocalypse would return and once again threaten all that lives. It was up to Terra to unite the galaxy against the threat that would one day return.

There are many directions we can go with this. 

A populated planet has been discovered nearby, and Terra sends a team that would vary in size, depending on the situation.

Interacting with another galactic empire that's recovering from the apocalypse.

On a planet that has allied with Terra and accepted her influence, we could go a more slice-of-life/magical individual route. 

Star Trek/Deep Space Nine-ish thing on the roving colony ship.

Or we can talk about what you'd want to do.

There's all sorts of options. I've left out some details, as well, because there's a lot of details, and I don't want to drown people so quickly.
