The caste system in Orzammar includes many groups of privilege--the nobility and the warriors above all others, but to a lesser degree the merchants and the smiths and the miners. Tradition establishes a clear hierarchy. But as in any culture with an upper class, there is also a clear underclass. These unfortunates, the so-called "casteless," are believed to be descendants of criminals and other undesirables. They have been looked down upon since Orzammar's foundation. They have taken up residence in a place called "Dust Town," a crumbling ruin on the fringe of Orzammar's common areas.
