Drow

In many ways, the Drow resembled other elves. Their bodies were wiry and athletic,while their faces were chiseled and attractivethough they were shorter and thinner than other elven sub-races. Due to a process of selective breeding that lasted for several generations, the Drow (especially nobles)looked attractive even in comparison to other elven subraces. Though their alluring appearance could be used for seduction, it was more often utilized to instill fear. According to the goblin Nojheim, the beauty standards of the surface races made them prone to turn a blind eye to the deeds of the Drow, showing them greater leniency and acceptance.

The moral code of the average drow was informed by the teachings of Lolth. From birth, the drow were taught that they were superior to other races, and as such they believed themselves to be the ultimate beings. This mindset created an arrogance so strong that drow could be incapable of viewing other creatures as their equals, including members of their own kind; almost every drow believed themselves to be the epitome of their superior species. The treatment reserved for non-drow ran the entire gamut from pets,to slaves, to grudgingly respected partners if they proved themselves a military match for them, though never equals.
