Duergar

Underdark Traveller

While Duergar are pessimistic and do not wish to travel above ground or far from their Underdark route, they do have courage and bravery if it ever comes to pass. When a duerger leaves their regions it is generally due to being cast out by their clan, or found escape from their society through petty crime, tattooed and then cast out from their cities beneath the surface. Understanding that trust is not an easy commodity they tend to have a more negative attitude toward strangers. Their attitude and grim demeanor made them unlikely to form many lasting friendships. However, with the promise of prestige and gold, they are able to work with others, and it takes time to both trust and be trusted by any duergar.

Behaviour

Duergar tend to be prideful of their lack of happiness and grim demeanor and consider it a great strength. They see themselves as having the true ideals of dwarves while the other subraces are weaker and pampered in life. They can be tyrannical, grim, industrious, and pessimistic with determination and bravery. 
Duerger are generally impassive, some consider calm, but their flaws can be to the extreme. They can be violent, hateful, sullen, greedy and ungrateful, cynical of others' motives. They also hold grudges for quite a while no whether the defense was meant. They have three primary principles to follow: Greed, Conflict, and Rejection of emotions. 
Tinkering is a common practice with dwarves, however Duergar only consider it valuable based on it's function and not much artistry or warm in the finishing product. However, they have an insaatiable desire for wealth and prestiage and many are not above stealing to get the gold. They believe that the weak were unfit to own what was meant for the strong, and those too weak to defend their property are considered the most unworthy of pity.
Distrustful of other races, but able to trade with other races for the sake of profit. If they had a pet they would most likely have bats, siders, lizard or other underdark creatures.

History

Eons ago, duergar came from an ancient ambitious and powerful clan of dwarves. The most powerful dwarven clan was becoming dismantled and many wanted to rule. When the smaller clans did not succeed in power they decided to separate from the major demographic. Mindflayers attacked the realm enslaving many of the dwarven population. During their captivity the mind flayers performed cruel experiments on the dwarves. The dwarves who survived these experiemnts through the generations became what we now know to be Duergars. Over time the duergar rose up against their captors and gained freedom from the mind flayers.
