With the flurry of activity around SFO lately, and the recent talk of an "official" background for Starmada, I've been giving a little thought to universe development (never my strong suit... I tend to get distracted by shiny things... )
With the snow coming down again today (over a foot, with more tomorrow) I've had plenty of time to sit around and think about this. Here's what I've got:
I'm thinking of this as a "Star Wars" type setting, with far-flung empires and vast numbers of peoples and races; so much so that it can only be described in sweeping arcs rather than specific details.
Forgive the vagueness of what follows: very little is fixed in my mind...
A thousand-year empire has collapsed under the advance of an extra-galactic threat. That threat has been eliminated (we hope), but those who remain aren't exactly sure that they want to reinstate the empire as it was. Old rivalries and even older ambitions see an opportunity. A new government of a sort has been put in place, but it is deliberately weak and ineffectual.
Among the factions now at large, the most powerful (and thus the most threatening to the others) is that of the NAME? Think of a conflation of the Borg from Star Trek, the droid army from Star Wars, the Cylons from the original Battlestar Galactica -- fully robotic foot soldiers (or are they?), led by cyborg-type officers, directed by ... WHO?
Another faction of note is the Emperor in exile -- when the capital was sacked by the invaders, the seat of government was moved far away. Most of his old subjects don't recognize the legitimacy of this Emperor -- they consider the exile to be a completely different entity -- but the Emperor believes himself to be the legitimate successor to the old Empire. He plans to reclaim his birthright...
The Assembly is the newly-constituted centralized structure, but it has no power of its own. Although many of the old members of the empire send representatives to maintain appearances, it has not been invested with any real authority. It has managed to establish a military of sorts, but it is little more than a collection of member-contributed units (think the blue helmets of UN peacekeepers).
The remaining factions are ... ? I don't see them as all fitting a particular mold. Some are the noble houses of the old Empire, others are subject kingdoms getting their first taste of freedom in a thousand years, still others are corporate entities who see the chance to make a buck (or a credit).
