Goblins are a healthy, thriving lot despite the attempts other races make to eradicate them wherever found. For the benefit of the world as a whole, this is probably not a good thing.
The goblin races are mortal, but like elves, they’re close relations to the fey of the Overworld. They are spiteful and cruel, creatures with the intelligence of adults but the solipsistic morality of children. Most have long, pointed noses and ears, and their skin tones are earthen, usually chalky gray to grayish-brown. They feature prominently in tales meant to frighten children and youths out of wandering afield at night — tales that are earnestly honest.
“Goblin” can mean one of two things: any member of the goblin races, or the smallest breed of common goblins. The latter run from four to five feet in height, and have the most childlike sense of malicious wonder. They are the commoners of goblin society, the dregs and peasants who serve their abusive betters out of fear. Most use scavenged and kit-bashed goods of poor quality, though some manage to achieve great station by holding onto finer goblin works.
Hobgoblins consider themselves the aristocracy of the goblin races. They are more the size of humans and elves, lean and lanky with overlong arms and fingers. They wear brown-stained goblin steel armor when they can get it, and practice more sophisticated (to a point) fighting styles. They are prone to petty infighting, fits of pique and irrational decisions, but overall they are considerably more clever and organized than their commoner relations.
In rural Rasenna, some of the most dreaded goblins are the Kallikantos, the “Hairy Men.” If common goblins are the peasantry and hobgoblins the aristocracy, these bugbears are the yeomans and country squires, the huntmasters and gamekeepers. Huge and muscular, the Hairy Men can overpower any of their lesser kin, but are generally too antisocial to gather in great numbers. The Kallikantos prefer to live in small hunting bands, stalking and trapping anyone who enters their chosen woods. Those they catch provide meat for the pot, blood to dye the Kallikantos’ pelts, skin for leather and bones for tools. Like all goblins, they can be greedy, and powerful goblin “nobles” often try to purchase the loyalty of a band of Hairy Men.
The warped fecundity of the goblin races being what it is, even more bizarre variants are known. Tiny goblin-imps crop up here and there, anywhere from the size of a cat to the size of a ten-year-old child. At the other extreme, some “goblin ogres” (or “ogre goblins”) stand as tall as nine feet, and are possessed of a gruesomely bloated bulk. There are even legends of “goblin giants,” goblins that never stopped growing until they reached twice the height of a tall man. The latter types are thankfully very rare even in the wild parts of Rasenna, but the smaller a goblin gets, the more likely it can thrive even in the heart of a human city.
Goblins are a recurring problem almost anywhere. In Rasenna, they are the thickest along the eastern borders, where they frequently send slinking, thieving raids out of the Widdermarches.
