Rise of The Runelord Anniversary Edition for 4, 5 or 6 Players using The GM’s Guide to Creating Challenging Encounters (SPOILERS!!!!)
For being a Justicar in that region of Varisia, you'd be under the jurisdiction of Magnimar, as Sandpoint, and most areas around it are part of Magnimar's official holdings (which stretches as far east as Turtleback Ferry, excluding Ilsurian, if memory serves). Magnimar and Korvosa both have jurisdiction within their own large holdings, and Riddleport even has a few towns nearby under its proverbial thumb.
The PC would have to be associated with, and probably ordained by the church of Abadar in Magnimar, and the local laws will change depending where the campaign goes. I'd suggest reading through Varisia, Birthplace of Legends to get a better idea of where the loose boundaries of each major city-state's holdings are.
As an aside, from a fellow GM of the same Adventure Path:
I'm impressed that the PCs were able to subdue Nualia and that they intend to bring her to trial. You should take the opportunity of the trial in Magnimar to introduce Justice Ironbriar, as the judge in charge of the trial. Have him sentence Nualia and any other survivors to The Hell's, but then have him scrub the prisoner transfer records so that he can take them under his wing. Level the Thistletop NPCs up and have them either work with the Skinsaw cult, or perhaps show up later in the campaign where it feels natural to have it fit their personalities/goals/intentions.
Always means always, which includes combat. Rules as Written and Rules as Intended say your GM is incorrect.
And if your GM still disagrees, then tell him that all creatures with swim speeds need to constantly make swim checks in combat as well, otherwise he's breaking his own ruling.
Swim Speed: A creature with a swim speed can move through water at its indicated speed without making Swim checks. It gains a +8 racial bonus on any Swim check to perform a special action or avoid a hazard. The creature can always choose to take 10 on a Swim check, even if distracted or endangered when swimming. Such a creature can use the run action while swimming, provided that it swims in a straight line.
I am also a fan of Chirurgeon+Wasteland Blightbreaker. Don't forget the Signature Skill (Heal) feat and the Precise Treatment and Battlefield Surgeon traits!
I second MageHunter on readied Vital Strikes. Crossbowman Fighter as a Kobold with their super tasty FCB option.
Shouldn't the list of "Sihedron Sacrifices" be part of Ironbriar's encoded journal/ledger? It makes sense that he'd have a list of potential greedy targets supplied by Xanesha, or ferreted out by himself or his minions, and a lot of the names would be crossed off at this point, I'd imagine.
"Hundreds of archetypes"
I love the sheets you guys do have, but there's so many popular archetypes that are missing that I'm disappointed more often than not when I look for one from you guys.
I'd pay money for some specific archetypes, and the ability to combine compatible ones onto the same sheet.
Detect evil pings on things that have definite auras (like clerics and paladins), evil alignment creatures with enough HD, and creatures of any alignment that have active evil intent at the moment of detection.
Edit: Scratch that, even if actively evil, he wouldn't ping until level 5, regardless.
This planet description immediately made me think of Darwin IV.
If you're feeling up to custom monster statblock creation, then do yourself a favor and hunt down a copy of Expedition by Wayne Douglas Barlowe.
I'm particularly fond of the Daggerwrist.
