Seminus demons are a specialized type of incubi, and until the birth and discovery of Sin, sister of Seminus demons Eidolon, Shade, Wraith and twin of Lore, is a male-only species. They have two maturation cycles the first at twenty that causes a painful need to mate or die and another at one hundred called S'genesis. A post-s'genesis male is capable of procreation and possesses the ability to shapeshift into the male of any demon species (cannot be smaller and must be a live birth species). Their paternal history is shown as a tattoo called a Dermoire on their right arms with glyphs for each ancestor ending with their personal glyph at their throat. The dermoire on unmated post-s'genesis seminus demons extends to their face warning females and neccessitating the shapeshifting because few demons are willing to raise a seminus. Many unmated sems go mad and lose themselves in the desire to breed as many females as possible whether or not those females have mates. Many are killed at birth or do not survive the maturation cycles and even those that do survive past s'genesis are killed by the mates of females they are attempting to impregnate. Mated sems have a ring around their personal glyph and only have a desire to impregnate their mate. Seminus demons are (aside from half human cambions) born pure blooded. They inherit traits from their mothers but these traits are usually to give advantages in mating.
