Different people hear different stories of his past from him. So far, he's been the son of a human concubine and Elvish lord, the orphan of a traveling merchant, and the political prisoner of the territory of Duran (among other things). His true history, however, he hides from most. The few who know it are either dead, old friends, or dignitaries within the military. Ry is actually descended from a low level noble family who sought to gain more prosperity for their holdings by entering their only son into military service during a long stretch of aggression between the Fae and the Elves. As he was not the female of the family and therefore had no claim to power, the only way for him to bring his house acclaim was through military service (or so they believed). The military allowed him a distance from family and awakened a bloodlust he took out on the field of battle against enemies. His unit became one of the most infamous ruthless units known by both Elvish and Fae alike as the Duri Khai, the Wing Cutters. From trophy taking (where they got their name from), to rape and outright murder of prisoners, their atrocities finally became too much for even the Elves to stomach, despite the unit's numerous victories.
In the end, their unit was disbanded, many of them dishonorably discharged from military service while the worst of them were put on trial, Ry being one of those who was prosecuted. The sentence? A choice of exile or death by public execution. Ry chose death just to show his jailers he was not afraid of them and that he had absolutely no regrets in his actions, seeing them as patriotic. When the eve of his execution came, he was approached by a cloaked figure who revealed himself to be an Elvish lord. The noble offered to have him extradited safely and given an employment opportunity that offered him more freedom in the execution of his duties and a more open establishment that believed in upholding Elvish society in a way that was not afraid to take risks in order to achieve goals. Ry accepted the offer and was spirited out of prison, another sent to die in his place. His family disowned him at his death and he was buried as a common thief would be without honors or ceremony.
And thus began a new existence for him working in secret for his benefactor and wandering the human territories, since to show his face in the Elvish or Fae realms would be suicide outside the sanctum of his noble benefactor. He has been wandering for hundreds of years working mainly as a Hunter or soldier of fortune when not using his skills to aid his lord.
