There are many aspects to Claude's personality. As a human he was a hard working young man with a heart of gold. He did everything in his power to care for his family, and even worked the fields in his beginning stages of sickness. This generosity seemed to follow him throughout his long existence, even as the cruelty of man seemed to put a damper on his compassion. Having such a long, fulfilling life has given him the opportunity to see the world through it’s high and low points but it never ceases to amaze him. He is often confused by the finer details of human interaction and is blind to social norms. His unbiased curiosity has made him increasingly wise as time goes by, opening his eyes to new creations and astounding possibilities. He exists in and out of time, being an almost omniscient role model to his charges—however naive he is about the way society acts today. Claude is merciful in character, except when you harm on of his Archers or his human charge. He is a man of strong moral principle and his leadership is unparalleled to even that of Alexander the Great. He is not one to let emotions get in the way when it will impair his judgment, but he has a weakness for those whom he considers his friends. On one hand he is this stoic, straight-laced authority who remains unwavering in the old ways and doesn't tolerate weakness. His overbearing intelligence and need to correct others is almost bothersome enough for him to be secluded from social interaction but the benefits of being his friend outweighs the bad. He also possesses an almost dark sense of humor that, although hilarious, is sometimes inappropriate in nature. He sees himself as a realist, and doesn't sugar coat much of anything—nor does he take the time to spare anyone's feelings. On the other, he's this effervescent, caring individual whom you can always place your trust and know that he'll be there to support you. The more you get to know him, the more you see this vivacious persona and few prefer him how he initially seems. The face he puts on for those he doesn't know and for those he considers his enemy is one of an impassive and brusque leader. He is merciless towards his foes, and will not think twice in ending a Siren's existence.

Claude was one of the first Archers Cupid ever chose, and his first ever success. He was born in the small English village of Canterbury following the death of the Archbishop. Seeing as he was born on the pre-determined day of match-making, Cupid saw him as an excellent apprentice. Claude's life was not long by any means, but considerably longer than most in his day and age. He died at the tender age of sixteen from Yellow Fever. After training with Cupid for nearly five decades, Claude was given his first charge. His name was William Rufus II and he proved to be a troublesome charge indeed. The man was well hated over the course of his lifetime, despite Claude's influence on him in his early life. William died in the New Forest before ever finding true love, though he did have a wife and many children. Claude did not let that deter him, however, and immediately requested another charge. This one proved to be more effective, just a nameless farm boy whom Claude helped find the love of his life. Cupid was proud of Claude's progress and efficiency and offered Claude his freedom. However, young Claude politely refused the offer, and it was that commitment to his work that led to Cupid's decision in making him the Leader of the Archers. From that day forward, Claude succeeded to fulfill his duty, never revealing his true identity or his abilities to any of his charges. His efforts were not always successful. Quite often, Sirens would seek to corrupt the humans under his supervision. Some of them were victorious; this led to the untimely death of the humans involved. Being a man of vengeful intent, Claude sought to it that the Siren responsible wouldn't live to see another day. This ruthless brutality was kept hidden from Cupid, lest he punish Claude by eradicating him. Claude cannot count on two hands how many humans were placed in his charge, but he can faithfully recount that only a few have ever meant something to him. Because of the threat of extermination once his abilities are revealed, Claude makes it his prerogative to distance himself as much as he can without putting the human in jeopardy. He doesn't allow himself to feel sentimental attachment to them, and only a few have left that mark. Even those who he felt close to never stemmed from romantic connection; he saw them merely as his children, if anything else. In Cupid's absence, Claude takes on the role as trainer for new Archers, teaching them how he was taught even though Cupid as adjusted his training methods with time. He seems to have grown found of a few operatives, even considering some as close friends. This being said, he holds no other Archer to a higher esteem than Iyla Noor. She was the first ever Archer he had taken under his wing and his last. He watched her during her last month of life alongside Cupid, kindly requesting that he take her on as his apprentice. Cupid agreed wholeheartedly, almost insisting upon it, and Claude watched over her until her day of reckoning. When the moment came for her to die, Claude watched her give birth to her first born child, appearing to her as she slipped in and out of consciousness during labor. When she died he waited for everyone to clear the room before resurrecting her, offering her the opportunity to help others find love when that liberty was so ruthlessly stripped from her. She agreed and from then on he took her on as his pupil, teaching her everything he knew: different languages, cultures, literature, art, and even how to play the piano. They became close in bond, seeing each other as devoted friends. He did not train her in the ways of the Archer, however—leaving that honor to Cupid himself. Instead he spent the time Iyla was away training to check on his new charge, Iyla's daughter Leena. He kept an eye on the orphaned child, introducing himself to the child as her imaginary friend—or rather, a figment of her imagination—instead of an agent of Cupid. He never revealed his abilities to her, nor did he address the fact that he never aged alongside her. Over time, he grew attached to Leena, just as he grew fond of Iyla. He made sure that Leena lived a long and happy life, even remaining at her side as she took her last breath of old age. He never told this to Iyla. His reasoning behind having kept it a secret is a mystery, even to himself. Nevertheless, Claude remains 'married to his work' and it is highly unlikely in the foreseeable future that he will give up his power for a mate or to simply end his immortal life.
