Once I get the second book, I plan to start full-bear building a campaign universe. Rather than a Dragon Emire, I'm using an ancient Illithid Empire. Combining high technology and powerful psionics, they're trying to expand their power through the universe, killing gods and subjugating planets as they go.
Humans and orcs are from the young planet Oerth, where they've been discovered by starfaring powers. Humanity is wanted by all for their versaility, allying mostly with the elves and dwarves (see below).
The Illithids have experimented on some, seeing their potential for psionics and magic both (they've been trying to absorb races with potential into their collective genepool so as to evolve their staid race. From this came the Gith. The Githyanki ride through space on the corpses of minor gods the Illithid have killed while conquering worlds and races, pirating from their body-cities into wildspace to get revenge on their captors. Meanwhile, the Githzerai have had their minds expanded to where they can see their potential. They've escaped to a gas giant on the borders of Illithidspace where an ambiguous race of mentalist beasts float through the viscous fluid atmosphere altering elements with their minds. The Flayers call this world after this race -- Slaad. The githzerai, however, await on this world they call Limbo.
Hukanity's first contact was with the elves. On the planet Arvandor, magic reigns and fey run free across its idyllic surface. The elves have melded powerful wizardry with simple tech to travel the universe by stargates. One such gate opened onto Oerth, where the first explorers where massacred by orcs. They now have relations with the humans (who have great potential for elven magic), but humanity is disturbed by the vengeance the elves show toward the orcish people (I see humanity and orcdom as coexisting -- imagine if the Neanderthals survived and we lived side-by-side with them).
In another star system lay two planets in an eon-old cold war. On one, dwarves (and their above-ground cousins, the gnomes) use the highest technology on its own to build a massive trading and industrial power. In orbit nearby is their rival, an imperialist world of equal tech ruled by hobgoblin lords, with their goblin and bugbear underlings. The dwarves respect man for their ingenuity and the hobgoblins have been providing the orcs with high-tech weaponry to strike at the dwarves through their new allies.
One race that's more than meets the eye is the kobolds. One of the first races conquered by the Illithid, they made a deal with their masters. The Flayers are unable to use magic, whose sorcery the little doggiemen are adept at. As such, kobold squads now roam the universe, vlad in the highest technology and many levels of sorceror to wipe out such enemies as the wizardly elves. Despite their size, the kobolds are feared -- while gnolls, minotaurs, and grimlocks may be the Imperial shock troops, the kobolds' precense means someone WILL be wiped out.
Three other races hold an interesting place in the galaxy too. The first are the Formians. Their hive empire is the second largest, only behind the Illithid. Their tactics, however, are different. Of insectoid mindset, they regard all other life as a threat, and their numbers and organization have wiped clean many a world. Their war with the Illithid Empire may be the only thing keeping the Supreme Intelligence on Penumbra from having the forces free to wipe out the Arvandorian, Moradian, and Oerthian threat.
In a distant corner of the universe, mercane traders ply their wares, selling to all sides, but favoring slaves for their secret masters. On a dark world named Gehenna, an ancient immortal race called the Yugoloth reign, buying and selling living things to torment for no other reason than to study the mysterious phenomenon of death. The Illithid Empire often sells those captives they can't assimilate to the Yugoloths through the Mercane Federation, if only to make their enemies more fearful.
The last, most mysterious, race of note is the dragons. In the dawn of time, they appeared from the center of the galaxy, great starwyrms that fly through the void of space on their own, seeding worlds with their children. On a thousand worlds, dragons of all colors are born and raise families, then those that survive past great wyrmdom take to the stars to seed new worlds farther and father then thri own ancestors flew. Their motivations and racial plans are unknown, and thy remain the one thing the Illithids fear.
I've got other tidbits planned, but that's the basis of things. Whatcha think?
