I've stocked it with the basics, but am interested in what else you all think needs to be in there. If you have suggestions for category division, or for more books, games, or other items in the Myth-Weavers Shop, post them in THIS thread!!
This adventure path will take place in the Inner Sea region of the world of Golarion, a setting created by the good people at Paizo for the Pathfinder game system. If you're not already familiar with the setting, you're in luck, because there are some useful online resources that will help you create your character's background, some of which I will link here.
The World of Golarion
The primary area where this particular campaign will take place will be Numeria, an expansive region located in the northeastern section of the continent of Avistan, although your characters needn't be native to that land, or even any of the neighboring nations, for that matter. Your characters will be agents of the famed Pathfinder Society, so it will be reasonable to write up a character from anywhere in the Inner Sea Region.
Note that you should use caution when using online wiki sites to gather information on the campaign setting, as some of those sites contain spoilers or information that does not jive with the timeline in which these adventures take place. With that said, what follows are some links that you may find useful.
Some additional information on the geography and history of Golarion can be found here:
The above sources, and the information posted throughout this thread, give you a general outline of the world of Golarion, but if you would like to read about it in more depth, or to have your own downloadable source of information on the Inner Sea region, there is a World Guide available from paizo that can be downloaded in pdf form at a small cost. It is a beautifully conceived and well written and illustrated piece of literature, but it is not required reading, as you can find all that you will need in the links above.
If you should choose to play a human, you may choose from among the following ethnicities native to the world of Golarion. Aside from giving your character some background and culture, your choice may also have minor mechanical benefits, such as deciding which regional feats are available to you.
Here is a brief decription of the major human ethnic groups found in the world:
Azlanti Language: Ancient Azlant Favored Regions: Absalom, Azlant, Cheliax, Taldor, Andoran, Varisia, Nidal Favored Deities: Humans claiming Azlanti blood often favor Aroden, last scion of Old Azlant.

Favored Deities: For many centuries, Chelaxians were almost exclusively worshipers of Aroden, the Last Azlanti. With that god’s death, they have turned to a variety of gods and beliefs, including Erastil, Iomedae, Zon-Kuthon, and the practice of diabolism, venerating the vile devil-court of Asmodeus.

These are the various regional dialects spoken by the major human ethnicities of Golarion:
These are the languages of the major non-human races of Golarion, and also those attributed to particular sects such as druidic. Of course there are many more languages native to the less prominent races of the world. Only the most common are listed here.
These are the languages native to races and cultures found in the vast subterranean area of Golarion known as the Darklands. Again, there are probably others as well. These are the most common.
Languages of the Great Beyond
These are the most common languages native to beings from the outer planes.
These are the ancient languages of Golarion's lost civilizations, and are often the building blocks for most modern languages.

In addition to the major religions that are listed above, there are also a number of other deities that would be acceptable, although if you want to choose one other than those I've listed, I'd rather you limit your choices to the racial pantheons, and stay away from those that are specific to other continents like the Dragon Kingdoms or Vudra.
