Bestiary monsters in Distant Worlds?

[Jek]

I was looking through Distant Worlds, and it mentioned some of the monsters in the Bestiary and how they relate to space and the rest of the solar system, and I found something that looks a little off.

Namely, the Tzitzimitl. If it does come of Eox, as the book says (ignoring that nothing else on Eox has an Aztec naming system), then why are there so few of them around? And if they were trying to kill off the rest of the life around them (which is the stated purpose of the Tzitzimitl, at least before Distant Worlds came out), wouldn't the Liches of Eox have cleared out the life on their own solar system first before sending them out to others? And while the entry of the Tzitzimitl itself has only speculation on their origins, if Eox made them then that makes pretty much all of it wrong. And the sages said that the came from the dark spaces between the stars--wouldn't people learned about space, presumably with knowledge of Eox and access to divination magic, at least know that it came from another planet that is in their solar system?

Also, it says that the Akata originate from the Diaspora. But the book said that the Akata came from a far away planet--well, if you go by miles/kilometers the asteroid belt is a ways away, but in regards to stellar distances it is pretty much next door (although this one isn't really that big a problem compared to the Tzitzimitl).

Is the point of view for the Bestiaries not set in Golarion, but generically no-specific-world? Because if that is the case, then it would make sense, but I thought that Golarion was the default world for PF products. If someone could clear this up for me, I would appreciate it.

I apologize if I'm looking too deeply into this, or if I sound a little rude.

The Pathfinder Role-Playing Game line of products is setting neutral.
Everything else (Campaign Setting, Player's Companions, and Adventure Paths) is set/centered on or around Golarion (cosmologically).

[James Jacobs]

We generally set up the monsters in our Bestiaries to be world neutral... but relatively close to how they function in Golarion. Still... there are times when things are different.

[James Sutter]

James and Nathan are right. With that section in Distant Worlds, I was trying to give ideas for how you could insert "setting-neutral" monsters into Golarion's solar system. You'll often find that, when monsters heavily tied to Golarion end up in a Bestiary hardcover, we deliberately obscure or alter the flavor a little, both to make them useful to a wider audience and to obey the rules regarding IP and the OGL. Distant Worlds is an example of the same effect running in reverse.
