Orcs and humans can interbreed, and this union creates half-orcs. Humans and orcs have been enemies for decades, and half-orcs represent something both races prefer not to think about. Half-orc genesis is usually violent and perverse, and "their appearance is too rough to be human and too clean to be an orc"APG 8. It reminds the parent races of the rift between them and the horrible deeds each has performed on the other. Thus, most humans and orcs ignore half-orcs. Other races are little better, as the human-orc conflict is only one facet of the Alliance-Horde tensions upon which no one likes to dwell. Conversely, some see half-orcs as symbols of unity. Not all half-orcs are born to abused or victimized parents; some are the children of clandestine love[.Perhaps half-orcs represent what could be accomplished if the races put aside their differences and live in peace. After all, if humans and orcs, with their history of hatred and bloodshed and wildly different origins, can produce viable offspring, perhaps the races are not as different as they think.
