I know there's no larger map (yet) of the galaxy. I don't have any of the older pathfinder sources either, so I was wondering if we know the shape of the galaxy and where the PW system lies in it?
I assume its a spiral galaxy like ours, and since Golarion and the system as a whole is an analogue to our own solar system, it stands to reason that it lives on the outer fringes of one of the arms of the galaxy. But if there's a reference for this anywhere, I'd be interested to know.

No, and drift travel (probably deliberately) makes it a moot point.
Drift doesn't care about the distance between you and your destination. It only cares about the number/size of drift beacons. So 10,000 light years? Back to absolom station is 1d6 days. 1 light year? Back to absolom station is ..1d6 days.

I think I recall that most of near space is supposed to be near the core of the galaxy, with most of the vast being the outer arms. So Golarion is likely nearer the core than Earth is.
Do we even know if Earth and Golarion are/were both in the Milky Way galaxy? We only know for certain from Rasputin Must Die! is that they're in the same Material Plane, the Pact Worlds could be in the Andromeda Galaxy for all we know!

I believe we know they're not in the same galaxy. Though I'm not sure if that's from published material or comments here.

James Jacobs has said as much, it might have also been stated in Reign of Winter.

True -- But the easiest default assumption is to assume that Golarion is just like Earth unless we are given direct information to the contrary. Thus, its location in its own galaxy should be not too far off from where Earth would be in the Milky Way.

So Intergalactic travel via magic is a possible thing? I thought that Paizo said Intergalactic travel is impossible by technological means and magic.

Outside of a given system, Drift tech divides the galaxy into two sectors: Near Space and the Vast. While Near Space worlds tend to be closer to the galactic center (and, incidentally, to the Pact Worlds) and the systems of the Vast tend to be farther out
The Pact Worlds are near the galactic center.

It's possible with a particular magic artifact with the right key (Baba Yaga's hut) and with a tech drive invented only once (the Divinity drive).

Okay, so we do have that "direct information to the contrary". That is good to know.
And because the Starfinder setting is so magic heavy, we can ignore any scientific information that might suggest that habitable planets at the center of the galaxy might in fact be impossible.
On the other hand, having the Pact Worlds that close to the center of their galaxy would make sub-light interstellar travel less insane in the Starfinder setting than it is in our region of space. The kasatha, for example, might be from a solar system that is less than a light year from the Pact Worlds.

Eh, that seems unlikely given they took 300 years to make the trip. Even before the invention of the Drift Drive ( as in, during the Pathfinder era ), sublight space drives were still pretty dang good. Good enough that I can't really buy that a giant generation ship built to evacuate a good chunk of a planet, isn't going to be averaging some decent chunk of lightspeed. Note that, even if their average acceleration were only 5 hundred-thousandths of a G ( which is only 0.5 mm/s^2 ), they'd still cover a one light-year journey in about 278 years. And they'd do it with an average velocity of around 1% the speed of light.

The kasatha were going to a specific Promised Planet, not just the nearest habitable one. And if they'd waited a couple more years they'd have been able to use Drift technology to shorten their trip by centuries.

For what it's worth the concept of a "galactic habitable zone" has been proposed but is highly disputed. The absolute core of a galaxy probably doesn't have any stars with habitable planets because of the conditions there - lots and lots of black holes - but space is unfathomably huge, and there's still plenty of area that far enough away from that that could be called the center.

I would like to state that, unequivocally, and for the record, that neither the Cyrunian people, commonly known as Witchwyrds, nor their chosen representatives of the Tetrad Combine, knew of the eminent emergence of Drift travel when we convinced the Kasathan people to load their entire race into a tin can and blast off towards a conveniently out of the wayhabitable planet.
I would also like to state that the Tetrad Combine specifically does not advertise any access to temporal manipulation devices, commonly known as "time machines."

If they were using sublight drives and took 300 years then the Kasatha homeworld has to be less than 300 light years from the Pact Worlds by definition. Probably a lot less.
Our galaxy is about 100 000 light years in diameter by comparison.
Sublight simply means less than the speed of light -- so a sublight drive with a maximum speed of 1/300 the speed of light would indeed take 300 years to travel a single light-year.
And, if any maps of the Idari exist, it would be easy to prove that its travel speed was relatively low. How much space does the fuel tank take up? If the engines are supposed to be firing for the entire 300 years, then the Idari would have a fuel tank that is several times as big as the living area on that ship.

It all depends on exactly how this particular sublight drive works. A reaction drive powered by antimatter could, if it has enough fuel, accelerate at 1 G to the halfway point and then decelerate at the same rate -- and that is as fast as would be possible in the real universe.
Has any Starfinder source given any sort of speed estimates for interstellar sub-light craft?

You should be able to approximate it by comparing the max travel time for insystem (non-drift) travel to the max distance between outer planets on opposite sides of the sun in our own solar system.

Not really, since that's all handwavium. And top interstellar speeds could be far faster, since you've got a much longer acceleration time - assuming you're got sufficient power/reaction mass/whatever your drive uses.

Yes really. I'm not suggesting you're solving for the intrasystem velocity, you're solving for the constant acceleration that accomplishes that travel time, then applying it to longer distances.

It's complicated.
Not clear to me why you say that's as fast as would be possible in the real universe. You could go faster in the real universe - just accelerate at more than 1G - which for example a species from a higher gravity world would be comfortable doing. Unless you just meant "you could do this in the real world too"?But you hit relativity limits on longer trips. It takes approximately a year to get close enough to light speed for that to become significant. Apparently it works out so the rule of thumb for 1G constant acceleration trips is that they take 1 year + the number of light years, so something 10 light years away would take 11 years to reach. From the perspective of an outside observer.
In fact, you can essentially turn off the drive after the first year and only use it to decelerate for the last year without significantly increasing the travel time. Obviously that'll mean free fall or some other source of artificial gravity.
Continuing to accelerate will however decrease the trip length for the passengers. To the point that you could cross the galaxy within the lifetime of a human passenger - though much, much longer for those left behind.

Yup with the drift it largely does not matter where it is located because effectively it is right next door to everywhere due to the way absalom station works.
The side effect of that makes me wonder how long they can defend the pact worlds. It is just about the easiest place in the universe for any drift capable opponent to stage an attack at.

The corpse fleet found out the hard way that attacking a space station that can jumper cable its defense systems to a god rock of literally mythic power levels ranks up there with saying "i'll be right back" in a horror movie.

On top of this, if you conquer the pact worlds you now have, what? A resource rich system at the cost of a crap ton of military assets, and a center of trade easily accessed by anyone in the galaxy... that you already probably had full access to. I'd bet that most big empires out there looked at Absalom station and said: "eh, not worth it, we get the same benefits by being a little bit nice".

But not everyone conquers because of economic reasons. I doubt that for example the Azlanti empire or Swarm consider the economic implications of conquering the Pact Worlds.
Not to mention if the invader already has an empire and thus is not overly reliant on the Starstone they could simply dismantle Absolom station (and use the stone to try for divinity again like in the past).
And I don't think Absolom station is all that powerful. There certainly seems to be no problem in performing hostile actions around it in Dead Suns and the Magefire Assault didn't fail because the station was too strong.
Then again, what benefits does the attacker really have? That he knows that it is there and that the supply lines are shorter. The only real danger is imo that (assuming the Starstone works a bit like the Astronomicon in Warhammer) that everyone out there knows that there is something in that system and might come looking while the Pact Worlds have no idea who is out there.

I'm pretty sure that's exactly why it failed, to say nothing of the massive fleet defending it at all times.
Dead Suns 1: In 7 AG, the bone sages launched the Magefire Assault on Absalom Station. The undead fleet was halted and defeated by the station's powerful defences.

In the, I think, Pact Worlds book it says that Absolom was under siege when someone reactivated an old doomsday weapon left from the time when Eox had its conflict with other planets which caused the Bone Sages to break the siege and hurry back to Eox to save their cities.

In general, while Absalom Station has been invaded and blockaded a lot in it's three hundred post gap years, the fact that it's still around speaks a lot to the quality of defense that the Pact Worlds and Absalom are capable of raising. As others have mentioned, while the station itself only has a few hundred million residents, it's "suburbs" include several thousand ships, most being incredibly well armed. The Armada, is no joke. While most of those in the Armada will likely flee, the fact that the Station has it's own defense forces as well as a readily available volunteer navy.

thejeff |
It's also likely that there really aren't any great Space Empires out there to invade it.
Before the Drift, FTL apparently wasn't really feasible - things like the Divinity Drive and uber-magic aside, and it's really hard to maintain an empire with parts of it separated by years or decades.
Ruling a single system, certainly. Maybe even colonies and outposts in nearby ones, though those we know of (Veskarium and Azlanti) apparently didn't even have that.
It is kind of a huge flashing light though and I'd assume basically every Drift-capable group out there has at least poked their noses in to see what's up. In many cases doing so covertly.
