Ptolus is primarily a trade city, serving not only as a major port but also as a link between the northwest and central portions of the Empire of Tarsis. About two-thirds of the population is human, with the remaining third being (from most populous to least): Shoal elves, Stonelost dwarves, halflings, litorians, Grailwarden dwarves, gnomes, half-elves, centaurs (aram), orcs and half-orcs, and others—lizardfolk (assarai), ogres, and far stranger things. (Some of those races might sound unfamiliar. Read on.)
