Firearms in Sargava and the Mwangi Expanse

[jabberwoky]

I realize this question can be solved with judicious use of the GM's rule zero, but I would like to ask it to see if I can get a in-canon answer. Are firearms commonly used in Sargava and the Mwangi Expanse? There seem to be several arguments for and against.

For:

• Relatively close proximity to Mana Wastes and the Shackles (which is said to have gunpowder by the end of Skull & Shackles adventure path).
• Presence of megafauna (dinosaurs, elephants, Mokele-mbembe) which suggests a demand for high-powered weaponry.
• Themes of Victorian-era colonialism in Sargava seem to imply a higher technology level than Mwangi natives.

Against:

• Presence of High Magic traditions among the Mwangi seem to be at odds with using firearms technology.
• Isolation of Sargava, given the Eye of Abendego and the predatory nature of the Free Captains of the Shackles could limit the flow of firearms.
• Humid, wet environment can muck with firearms technology quite badly.

Thoughts and other arguments either for or against are welcome.

Pro:

- Alkenstar has a tradition of mercenaries, alchemists, and engineers serving in other nations. The campaign trait Get the Cargo Through would probably be appropriate.

- As mentioned, guns are rare, but not unheard of, in the Shackles. The campaign traits Boarded in the Shackles, Jenivere Crew ("reformed" pirate?), or Stowaway are possibilities.

Con:

- Much of the AP will take place in wilderness and ruins, which can limit the amount of supplies available for making bullets, alchemical cartridges, guns, etc.
