As an honor I will allow you to name the kingdoms setting while I plot here, I am okay with smut, but rather stay more plot progressed. Though I wouldn't shy away from romance for your sake.
Once upon a time in the Kingdom the Elves after a war with humans who chose to use machines to slaughter many of them in open warfare. The Elves descended into a fury of anger, anguish, and suffering at the cost of humans machinations. All the while Elves retreated into the deep woods establishing a new Kingdom from the ashes of the old. However they are not complacent in moving to the deep woods, they seek to unlock ancient mystical arts along the way in an effort to unlock ancient gifts.
Suffice to say this causes a rush back to the woods, to rebuild the population. Many Elves becoming refugee's in the woods against all odds forming small villages to rebuild, rebirth more of their kind. Meanwhile many Elves are unlocking gifts that seemed impossible before, within them Psionics make a revival in the deep woods while many in the population seek to better themselves. At the apex of the war against humans the Elves made a few forbidden weapons in their pursuit to secure a cease fire against the elitist humans.
Three great weapons that for now lay dormant in the ruined home-land of the elves forests of old. For now Elves live on in anguish trying to mend, and come together once more in spite of the times. Mysticism has become a new way of life for many Elves now, many communicate with crystalline, tree's, and the oceans. Many Elves are now psychic, and have various gifts among them that are not to be underestimated.
Within the Royalty of the Elvish Kingdom there is a new power heralding within the Queen's domain. Even as she seeks the secreted weapons within the Elven Kingdom within the confines of protection within the deep woods. The Queen's Council plots to make the weapons strike a mighty blow against the Human race out of spite to the Queen, and Human interferences. However, not all of the Elves are so convinced that violence is the right choice now reunited with their homelands in the deep woods.
A secret soldier has been deployed to the deep woods, from one of the boarder towns that the Queen was forced to relocate to in the War. A soldier seeks your character, an rumored person of interest in the deep woods noted to have Psionic Blessing from the Deep Woods. What you do not know is that he too has the blessing much to your surprise despite whatever your characters history is, he is a soldier also blessed with power.
What we know so far about the War with humans it hurt a good 30 percent of the population of the Elven Kingdom. People are humble in spite of this, and want better for their people in these early brutal times, however many per chance are optimistic something good can happen.
Others however have adopted heavier militarism to oppose the humans using many mechanisms they wouldn't have before. Even going back to a harder time of using crude weapons that are enchanted by magic.
Other Elves sold themselves into the military to oppose all humans in an effort to quash the human menace in their eyes. Many Elves adapted to the older human art of using modern military equipment, and resources captured from humans in the last war. Elves all surround themselves with competent teams of gun squads, in opposition to humans with the Queen's permission. They tread to the great north where they conspire to build weapons that will destroy the human race.
The Dark Elves head underground confronting old gods, and spirits that will enable them to strengthen their ties with their Elven-kin in earnest. They plot to going back to rogue, and assassin classes in an effort to kill as many humans in guerilla warfare as possible. Suffice to say the Dark Elves turned out much worse in this arrangement unfortunately.
Your character would likely be noted to be a bit of an outsider to the royal class of Elves that stay in the old country that was decimated by war. The soldier in route knows only duty, and the gift that he has with the weapon in his possession. The sword that he wields has uncanny psychokinetic power, at the cost of the conscience of the user. Its hilt has the ability to deflect fireballs and minor magical attacks.
Magic is making a recovery in the land as many of the Elves are regaining ancient senses, and balancing it with activity. The world of humans is in turmoil at present, much self loathing, greed, and ambition blind them to avarice and disdain in the most common of things.
