Numerous psychological tests have been performed and it has ultimately been determined that orcs are unsuited for city life; almost all lash out violently and cannot maintain a civilized demeanor. Half-orcs are a different matter. While most can have violent and terrible tempers, many have learned to work through their racial urges and live amongst humans.
Half-orcs (frequently called “Orcish", since even those with significantly diluted blood retain enough orcish features to be lumped in with true half-orcs) look much like humans, but are usually heavy-set, possessing of an underbite, a jutting brow and leathery skin. An unlucky few are even cursed with a pair of jutting tusklike teeth, which most have removed surgically. Most half-orcs are considered ugly by other races, though some tend to wear their features well.
Half-orcs are frequently considered second-class citizens in New Washington and are frequently the target of derision, but some have earned a great deal of respect. The Mercenary District is generally the best place for Orcish, as their strength and instinct will earn respect from the more utility-minded citizens.
