The Duergar are more commonly known as Grey Dwarves, a malevolent breed of Dwarf that is most often found at extreme depths beneath the earth. They prefer drap clothing designed to act as subtle camouflage, blending in with their rough underground homes, as though the darkness were not enough to hide them. Duergar society is very harsh because of the hostile environment in which they are usually found in these steaming depths, the strong are truly the only ones who can survive. They are more intelligent and dexterous than their Dwarf cousins, but usually weaker and less hardy, much the way that the Drow are weaker than their Elven kin, though Duergar are typically a bit larger than Dwarves, if only by a few inches. They speak the Dwarven language, but they do not at all enjoy the company of dwarves, and the two races usually attack one another on sight.
Dwarves are the tallest of the "miniature" races, but this does not by any means make them tall. They are stocky fellows easily identified by their diminutive size, wide and muscular build, and their abundant facial hair of which they are very proud, often braiding their wiry beards into intricate patterns before work or battle. They are known for their strength and courage, if not particularly for their intelligence, as well as their insatiable appetites for beer, ale, mead and stronger drink. Dwarves like the earth and dislike the sea, the latter no doubt due in part to their stubby limbs being unsuited to swimming. They are not overly fond of elves and have a fierce hatred of orcs and goblins, attacking the latter two as well as their own Duergar cousins on sight much of the time. Dwarves typically dwell in hilly or mountainous regions where caves are plentiful. Though not very charismatic according to the judgment of non-dwarf races, and not particularly swift, dwarves have an awesome endurance that makes them very difficult to keep down in a fight.
Halflings, much as their name implies, are small humanoids, generally two to four feet in height and ranging between forty to a hundred pounds. Halflings to have rather plump bodies, with dark, curly hair atop their heads and feet. Their feet are also disproportionately large, making them dislike shoes, though they don't need them thanks to the thick soles on the bottoms of their feet. Halfling eye colors have the same range that Humans do, and they are naturally agile and rarely make a sound when they walk.
