Xelodolphia, the kingdom of sex

As the demon lord and his armies had grown to a considerable size it, when it came time for the other forces to strike back the demon lord's forces were split in the southwestern part of the continent, leaving a large enough land for a nation. Thanks to this the main players leading the armies in that cut-off region were **** to come to a compromise, declaring themselves independent and hostile to the demon lord. Secluding their nation from the others due to racist ideals and ideologies, allowing the sex-based races to gain popularity as it was the succubi and female orcs that were the only female members allowed into the army. Leading the descendant kin to be of those 2 races, orcs and succubi, until the genes were completely overtaken, instead of creating males or females of each species, the orcs and succubi would go to the dominant gender of each species, that being male orcs and female succubi.

As time progressed their species would become acquainted with one another and diverge from their original paths.

• Whereas normal succubi would gather male semen and have a chance of producing incubi or succubi with a ratio of 3/4 (female primary), the succubi would instead take on their orcish partners' traits, becoming stronger slightly physically, taking care of their muscles in an alluring design while still maintaining their attractive and busty figures.
• Orcs on the other hand would gain a minuscule magical aptitude, greatly surprising everyone who knew the orcs as a race solely strong and reliant on their physical prowess, allowing them to become deadlier.

While the 2 would take on traits of the other, they would also have other lesser traits that have the potential of showing themselves like orc tusks on succubi or dormant traits like kobold fur. Though various demon lords and forces would come to rise and fall, this nation would always stay and remain a neutral party, when going to war, taking many prisoners to be used for sexual reasons.
