Entrances and exits from cities, especially less-guarded access ways around sewers and the like, are skulks' favorite stomping grounds. These sites allow them to closely observe who comes and goes from the city while also affording them swift escape options, should the authorities uncover their presence. On rare occasions, a well-disciplined skulk can rise to prominence within the local thieves' guild and become sought after for difficult jobs. Their repugnant personalities and overwhelming selfishness, however, usually means they are unable to secure long-lasting leadership roles.
