IMPORTANT INFORMATION TO READ BEFORE READING RACE ARTICLES

Races have been split into four categories:

Common Races

Uncommon Races

Rare Races

Wild Races

Races that are listed as Common Races are those which are populous and frequently encountered enough that most characters would have the information provided within that race's specific article. These races can be considered well-known and populous enough that information found in their article can be safely assumed to be known by your typical character and acted upon.
Races that are listed as Uncommon Races are those which, while occasionally seen depending on where a character goes, are not encountered on a regular basis and make up a significantly smaller portion of the population. Because of this, the information in these articles is not information that any typical character would know, and as such should be avoided as usable information by a character unless there is a very specific, reasonable, in-character reason why said character would know details about this race (for example, the character is that race). Assumptions made about how that race behaves, what they value, etc, without reasonable and specific reasoning or previous experience with said race should be considered meta-gaming and should be avoided.
Races that are listed as Rare Races are those which, unless a specific reason in a character's backstory would justify their knowledge of that race, should be considered as completely foreign to a character. These are races that are rarely, if ever, seen by individuals outside their own race, and as such should be considered a complete enigma to a character until they have had experience in interacting with said race. If you encounter race X and do action Y because you know race X responds to action Y in Z way, that is absolutely meta-gaming and should be avoided.
Races that are listed as Wild Races are those outside the civilized races listed as Common Races, Uncommon Races, or Rare Races. These are races that, while sometimes having their own social structures, are rarely seen within the larger societies of the other race classifications and are (depending on the race in question) hostile toward the other races. This makes Wild Races different from Rare Races in that Wild Races oftentimes have been observed or interacted with in some capacity that can be passed along to others, whereas Rare Races typically have developed societies that are highly secretive, reclusive, or are ruthlessly efficient in their hostility towards intruders, making them a mystery to those outside their own race/society.
