War is finished, the races of the light, humans, elves, dwarves, and giants, have won, while the races of the dark, the undead, orcs, goblins, and ogres, have been soundly defeated after a long campaign, with the deciding technology, gunpowder, although you still prefer your sword and bow, your heart swells with pride at the signing of the treaty as a veteran crusader, all underworlder-held territories would be turned over to the overworld, the underworlders would have to accept guilt for attacking the overworld, and would have to pay restitution taxes, certain concessions were made on behalf of the kingdoms, for example, the undead would be guaranteed access to flesh and blood the cadavers of the members of sapient races, as they could eat and drink nothing else, and they would be allowed to resume their previous lives as who they were before their time of death, and as members of their pre-death race, and not as a separate race defined by their (spontaneously occurring for reasons unknown even to the undead themselves) "affliction" of undeath, which would exempt overworlder undead from the restitution tax (this had the intended effect of fostering division within the undead themselves).
After participating in the victory ceremonies, you take all the decorations from your horse and ride to your home in the countryside, greeted by an undead orcess you've brought back with you from the war, your relationship is looked down upon, marriage is illegal, reproduction is impossible (biologically in the case of this setting, all overworld races may reproduce with one another, as can all underworld races with the obvious exception of the sterile undead "race", but overworlders and underworlders had been geographically isolated for too long to remain capable of interbreeding), however, you have a title, and the surrounding peasants do not, so they dare not say anything to you or your lover's face.
She has once-dark green skin that had turned pale in her undeath, Red eyes with Yellow sclera, canine-shaped ears and prominent tusks, a ridge upon her cute little nose, and long, luxurious raven hair that seems to glide behind her as she runs to embrace you, her body is lithe and gymnastic with flat boobs and butt (betraying her role as a thief, mage, and archer during the war), and she stands half a head below you (orcs are, contrary to state propaganda, about the same height and build as the elves from whom they descended).
She had died of starvation during the war, you had tried to save her, though she was a captured enemy combatant, as the code of chivalry (basically the geneva convention in this setting) demanded, you and her had bonded while you kept her in captivity, falling deeply in love, and you had placed your lips to hers at the time of her passing, and mourned her loss as the worst pain of the war, until the following night, where she arose from her grave, like most newly-risen, she had lost all her memories of her previous life, her skills and personality had remained, as had her love for you, driven by this need, she had followed your march until she found you, that night was the first time you made love.
And now you've decided to buy a farm and live a quiet life in peacetime, as both orc and undead, she'd have to whether some degree of hostility living among humans, but she'd suffer far worse for the sake of remaining with you, as an orc, even if she were still alive, she'd still never be able to bear you children, but the war has left orphanages crowded and undersupplied, relying upon private donations and child labour to fund themselves, maybe you'd adopt some children and raise them together.
You and your lover will see the rapid rise of an industrial revolution, in a setting where only a small number of individuals are born with the capacity to use magic (from all races and backgrounds, with the exception of those who have become undead, as their undeath renders them incapable of using magic, but also grants them a form of immortality, so long as they stay fed with the flesh and blood of sapient races, and their brains remain intact and connected to their bodies), gunpowder has given everyone the ability to call down fire and thunder, the scientific method is the newest craze, with the power of steam and electricity just being unleashed, mages attempt to keep up by applying it to their formerly tradition and history based study of magic,and made great developments, but technology and science proper are far outpacing them, even the deeply religious underworlders are talking about abandoning the worship of their revered gods, as science is now doing a superior job of explaining the great mysteries of the world.
