Half-Orcs are the result of mixing human and orc blood. Half-Orcs receive mixed reactions from nearly every society and often tend to be loners. They are typically on the upper end of human heights, around 6 feet or so, and tend to be very muscular. Half-Orcs have no real society of their own and are often found doing jobs that take advantage of their natural strength.
Though all living Half-Orcs are at some point related to both a human and an orc, they are not necessarily the off spring of such a pair as two Half-Orcs can breed, creating yet another Half-Orc.
