Well, back to the worldbuilding notes. :D
Eodea has goblins among its humanoid species.
They have pointed ears, big noses, and projecting jaws with marked canines. Their hands have two thumbs, one on each side of the palm, and three non-thumb-fingers.
Their sexual dimorphism works out to male goblins being around 3-4 feet tall, and female goblins 5-6 feet. Women are also more long-lived, and rarer - I haven't settled on a number yet, but something in the ballpark of 5-10 males for each female in a population.
So they have a reason for a tendency to protect girls and woman. Also for polyandry. The longer lifespan is a factor for women being most of their leaders, lorekeepers, judges, scholars, etc.
Goblins in general, and male goblins in particular, tend to be very group-oriented. I'm sure there are humans who have interpreted an unwillingness to make important decisions alone as sign stupidity or cowardice.
There is an insular nation of goblins in the mountains of Raaji.
In Konda there are smaller goblin communities integrated into a society dominated by humans. Particularly in the capital they are known as expert craftsmen, usually by the name of their legacy-lines - small teams who work together and trace their training back through generations.
Yrn was a settlement founded by goblins; they still make up about a third of the population, the rest again being mostly humans.
In northern Akadan there's a culture whose makeup by species includes goblins along with orcs (majority), elves, and humans.
What is your personal mental image of goblins?This entry was also posted at http://anke.dreamwidth.org/406344.html. You can comment wherever you prefer.
