Neat-o!
When I saw the title, my first thought was "Why would Asteroids form colonies? I didn't think they were sentient, let alone social!"
in Warhammer 40k Black Crusade there was a Asteroid belt that was inhabited, the gravity on the asteroids was "naturally" normal due to chaotic influences and yet you could jump to near by asteroids. however if you did it wrong you could easily die.
Some good ideas for my village/town/city deck topic. You could add a clock tower with 8 faces, each showing the time of day for a different world.
An asteroid jumper would need an amulet of adaptation and a bottle of air or water for propulsion. These could range from Pathfinder society members to smugglers.
I'm going to create a ritual for Attuning an Obelisk or Stone Circle. Restoring the Obelisk, or adding one that supports methane breathers next door, will require cultists, which the Sneeple happen to be.
Go to Link.
