Doesn't it just start with the MC placing an NPC between two PCs?  That creates a triangle, right? Because it makes the relationship between the two PCs different.  Yeah?  And then it just snowballs from there.

I don't know, man.  My instinct is to say that it's not the MC's job to challenge the characters or make life difficult for them.  Your job is to be a fan of the PCs and your job is to play your Fronts.  So I feel like answering your question requires me asking: so what are your Fronts?  There's nothing wrong about being a gang of murderous assholes in AW, so I would suggest embracing it and trying to think about how to bring your other Fronts into play so the PCs can murder them too.

Splats

There are only 3 splats in Firmament so far, though there's much greater diversity within splats because they each have many more moves than the standard AW splats and starting characters still get roughly the same number of moves.

The starting splats are based on the Three Sciences: Cartography, Archeology, and Astronomy.

Cartographer

Cartographers are dancers who map out routes between the stars through body memory and teach these dances to others.  They do not rely on the physical markers ("beacons") that the other Sciences prefer but instead trust themselves to their own bodies and impressive skills.  Consequently cartographers can be both useful and dangerous to keep around because they are good at leading groups into unmapped territory but are most frequently the sole survivors returning from travels in which the rest of the party was lost.

Cartographer's moves looks like Fingers in Every Pie from the Maestro'D book, the travel equivalent of NOT TO BE FUCKED WITH (Gunlugger) which makes them much more immune to becoming lost, Daredevil (Driver), and the Chopper sex move ("It's Not Like They Own You Or Nothin'"). They are a Skinner / Operator / Battlebabe combination, dangerous and headstrong, but extremely talented. They have new special moves for creating paths between the stars and teaching them to others.  Their special travel move may look a lot like the Flow With The City move from Dead Weight. They are really Cool and Hot, though the final stat list will probably be unique.

Archaeologist

Archaeologists focus on finding lost secrets and deciphering the ruins and other artifacts left behind by previous human communities amidst the stars.  There is strong evidence that ancient starfaring communities marked roads with monuments and runes that contemporary people can uncover and use.  Additionally, some left behind treasures or tools that are far beyond what we currently understand about star travel, since the contemporary human community has only existed for a handful of years.

Archaeologists' moves look like Shreyas' "When you wield a thing of power" from Set Apart, Things Speak and Oftener Right from the Saavyhead book, and Fucking Thieves from the Chopper book.  They probably have a Workspace equivalent in the form of a particular set of ruins or ancient artifacts that they are in the process of deciphering.  They probably start with at least one "thing of power" that they have uncovered the workings of. In AW terms, they are Sharp and Weird.

Astronomer

Astronomers focus on the basis of starfaring: the stars themselves.  They commune with and channel the energy of the stars as a way of better understanding how the humans who live among the stars came to live this way and how we can make the best use of the strange powers we now possess. Unlike the other Sciences, Astronomy is based on actually forming relationships with stars, though Astronomers will be the first to tell you that communicating with the stars is like communicating with trees or humpback whales: theoretically possible but practically difficult. Astronomers can also feel the star energy that has been transfered from stars to human beings, the energy that is the basis of human travel and survival among the stars.

The Astronomers have moves like the Brainer, Angel, and Hocus. They lead the star cult, have the healing touch, and can Go Aggro on people with the light, burning them alive.  They are also really good at creating beacons, which is probably a new move. They may also have a Workspace equivilent, the star that they have developed the strongest relationship with. In AW terms, they are Hot and Weird.

I agree with Amy and honestly think it might be easier to make farming a gig.  But I love the splat in general and if it's working great in your game, awesome.

Vx: Can I have one for "Fingers on the Firmament" please?  When you embrace the darkness, roll + Weird...
