For as long as Orin has remembered he has been a wandering sword. He was never gripped by the same mad bloodlust that struck others of his kin, causing them to go on wild rampages until some human finally managed to put them down. Orin actually managed to pass by unnoticed for a Kennooni most of the time as he exclusively hunted those who could give him a good fight. Those who would make him put his life on the line during their duel. Though Kennooni do not make a habit of counting the years since their birth (age is irrelevant to them, they were born to kill, and shall kill until they are killed. How many times the winter comes between those two points doesn't matter to them) he does remember having been brighter when he was younger (relatively speaking anyways). He would look forward to every new fight and would rush impatiently to find someone else who could excite him after each kill.
After he had made a name for himself as a powerful hunter of elites however, he came a cross a woman, a bandit from the south who had formed her own guild and had heard there was a nice price placed on Orin;s head from the employer of one of his former victims. A woman who remains to this day the only person to have ever defeated Orin in combat. The woman had proved herself a powerful enough warrior not only to defeat the kennooni but even subdue him without killing the spirit. By the time the battle had ended, the woman had enjoyed herself enough to grow to respect the fearless demon of the sword and decided to spare his life rather than collect the bounty. Orin was at both times overjoyed to have found someone so powerful, and furious that he had not been killed by the one who bested him. He became obsessed with the bandit queen and hunted her down relentlessly once his injuries healed. He had managed to track her down a few months later and once again challenged the elusive bandit, but even having become stronger than before, he was again defeated and left within an inch of his life to heal and chase after the bandit queen again.
And so a strange romance developed between the demon and the mysterious, seemingly human woman who continuously defeated him, revealing more and more of her seemingly infinite power and combat ability every time he challenged her again. His initial frustration at not being killed subsided, and Orin grew to enjoy the simple fact that he could experience the thrill of facing a truly great opponent over and over again. Though Orin does not know how many years passed in that time, he knows that he and the woman duelled a total of seventeen times, each but the last one having ended in a loss for him. The last battle was a tie that left the both of them unconscious (though the queen's guildmates retrieved her body before either could wake up). After this final duel, Orin finally felt ready to end things with his long time rival and love. However, he was never able to find her again afterwards. Searching all over the land for her, the woman who has been his rival couldn't be found anywhere. Eventually he became frustrated and tracked down the location of her guild's headquarters, going on a rampage through the bandit base and interrogating everyone he came across as to her location. However they all did nothing but feed him a lie about her passing away when she had contracted an illness while recovering from their last duel. Refusing to believe that his rival could die such a common death, Orin slaughtered every member of the guild in the first time he was ever overcome by the mindless rage so endemic to many of his kind.
After this Orin resumed his wandering travels, always looking for his rival. While he has met several powerful warriors who gave him interesting fights since then, he has stopped looking forward to these conflicts as none can compare to the pleasure he felt facing the bandit queen. He doesn't know how he arrived in this all too flowery and happy kingdom, only that he woke up there one day while on his travels. He figures however that whatever force brought him to Astareon may also have caused the disappearance of his lover in his own world, and intends to continue his search here now.
