Orcs

Orcs are naturally-occurring constructs who occasionally have members who are as intelligent as members of the six races, but are mostly known for being monsters that are driven by their instincts to kill, rape, and pillage..

Politics
Before Simon’s involvement, orcs have never had a nation of their own, but stead they tend to be dominated by Incubus Kings in order to be disposable soldiers or slave labor. On Arclent, "wild" orcs are either remnants of the invading armies of the Incubus King, or groups that have "leaked" from his domain.

Biology
The exact nature of orcs is unclear. During his stay in the Orgasmic Empire, Simon learns that they can impregnate succubi, giving some weight to the idea that orcs are the male counterparts of succubi, and some scholars even argue that they should be called "incubi", though the disapproval of the Incubus Kings has discouraged the practice. On the other hand, things are not as simple as they appear - the child of an orc and a succubus is always a succubus who inherits no traits from her father, and the orc breeding specialist Balia says that orcs are unlike any other race and describes them as "naturally-occurring constructs". Learning more about orc reproduction provides further evidence of their strangeness. All orcs are male, and despite their extremely aggressive sex drive they seem to be able to impregnate only succubi. Somewhat paradoxically, orcs themselves reproduce asexually, via fragmentation - they grow bigger and bigger, until they split into pieces, each fragment becoming a new orc. The "child" orcs mostly inherit the traits of their "parent", but any deviations from the baseline (increased strength, intelligence, etc.) tend to get diluted and diminished among the rising number of offspring. This is why the process results in sub-par orcs when left to its natural course: orcs blindly follow their instincts and grow as big as they can, splitting into many pieces, and repeat the process again and again. As a result, one of the basic tenets of orc breeding is keeping orcs into narrow, confined spaces, such as caves and pens. The breeding process itself is at least partially powered by lust magic, which is why sex does have a role in orc reproduction - orcs having sex accumulates lust energy. This also means that contamination with outside magic is possible if the process is not consciously controlled by a breeder. Contamination is one of the reasons for the appearance of unusual orcs and regional varieties, such as the "snow orcs" mentioned by Balia.

Orc Intelligence
Most orcs are barely smarter than animals, but many do possess intelligence closer to the average human level (which is not much...), and some even above it. Aside from the most obvious examples (listed below), other intelligent orcs include the orc representatives present at the Gathering, as well as the Lustlord's skeletal palace guards and captains (one of them is even shocked when Balia produces a "mindless brute" during the tournament). While orcs are still treated mostly as cannon sword fodder, you'll have the chance to meet a few remarkable ones with personalities of their own.

Orc Subtypes
While orcs are somewhat diverse on the individual level, larger cultural and "racial" differences do seem to exist between the orc armies due to both natural selection and directed orc breeding efforts. This is made evident during the Gathering, when Yarra's group meets the orc representatives, as well when Orcent fights in the orc tournament. Notable orc varieties include imps, Erosian orcs, skeletons orcs.

Ogre
Ogres are giant orcs that are result of a bunch of orcs combining together at the end of the orcs’ life cycle. If the ogre puts of splitting into newly “born” orcs, then he is the strongest orc type. Ogres are often used as guards and shock troops.

Imps
Imps are winged orcs that are much smaller than the average orc. While dumb as regular orcs, imps don’t have any physical or mental advantages to advance in orc society. However, their ability to fly does make them useful scouts.

Skeleton orc
Skeleton orcs are a type of orc in Rorak that shows more bone than flesh. However, they still do have penis.
