So the other day my father & I were stuck in a garage waiting room waiting for a car repair. Whist there I grabbed a holiday flyer & with a ball point pen I outlined a good chunk of the upcoming Colonial ACK's campaign. A campaign setting combination of Colonial Troopers & Adventurer, Conqueror, King rpg. And the subject of the 'Precursors' alien race came up. The 'Precursors' are a series of alien races that existed in the previous universe to ours. The 'Precursors' are now awakening after billions of years & the Terran Empire is fleeing before them. This is going to pick up right from last week's session report.
For one of these races I'm using the Zaharan empire from Adventurer, Conqueror, King rpg's Sepulcher of the Sorceress-Queen as the basis for this power. An empire of space going necromancers capable of raising undead alien troops to rase planets. They also used negative planar energies for megastructure construction. The power vacuum that they left behind on the interstellar scene was taken over by the Greys.
The Greys have been in charge for a long time or so they think. They found some of the interstellar technological works of the 'Precursors' & knew enough not to mess with them. Instead they used their own stellar harvesters to shepherd any number of new stars for Star lifting. And the Greys practiced stellar husbandry for thousands of years. But they crossed paths with 'the Bugs' who created massive hive Dyson spheres & began raiding the Grey's gas giant refineries.
The Greys meanwhile have treaty with the Cloud Giants, this is one of the first races to emerge after the 'Big Bang' & the cloud giants use a variation on Stellar engine principle. They used this to create mini planes for themselves to explore the multiverse. They also taught the Greys stellar husbandry to take over some of their star fields. The Could Giants retreated into their own star systems after overseeing a galatic empire for several million years. They simply walked away leaving space dungeons & ruins in their wakes.
There has been some speculation among my players that Kanahu is actually an Alderson disk just like Astonishing Swordsmen & Sorcerers of Hyperborea is. There have been no adventures nor revelations confirming or denying this. And this brings up the Skinnies who within our campaigns have several Anderson disk colony worlds.
Suddenly the players have realized that controlling one or more of these megastructures could be incredibly profitable. There are however several alien races that might have a thing or two to save about this. For the past few months I've been looking into Alternative Armies Ion Age miniatures to simulate one or more of the races we're playing with.
