Guillemin Karly

Doctor Guillemin Karly is a brilliant scientist and specialist in alien technology and engineering. He is the son of the late Matthias Karly, who created the PRAETORIAN Guard, the principle military defense of the planet Athena during the Human-Covenant War. Following the end of the war, Guillemin has taken on his father role as one of the heads for the PRAETORIAN Program, helping to advance the program with the use of new technology.
In 2557, Guillemin and SPARTAN-III Jason-G084 followed the remnants of a small post-Covenant faction called the Testament, which fled to Installation 02. Both were pivotal in defeating the Testament on the ring's surface. Guillemin would be vital in battling against the AI Created who took control of Athena during the Created Crisis. 
==Biography==
=== Early Life ===
Guillemin Karly was born on February 2, 2525, to Rebecca and Matthias Karly in New Athens, their only child. His father was a renowned scientist, while his mother was a history teacher. He was named after Rebecca's grandfather, Guillemin Simon. Guillemin was raised in the city of New Athens, attending a local education school. 
=== Human-Covenant War ===
Guillemin was 5 years when the Covenant first attacked Athena in 2530, his first interaction with alien life. Four years later, during the long and drawn-out land war between Athenian forces and the Covenant, the city of New Athens was assaulted. Guillemin's mother, Rebecca, was killed in the fighting, but Guillemin was ferried off to a safe location. 
His father would go on to join the military as a technical adviser and one of the senior scientists for developing anti-Covenant weaponry. Thanks to his father's position, Guillemin was given special academic training, pursuing numerous degrees in xenoarchaeology, xenoanthropology, and mechanical engineering. In his teen years worked closely under his father and other well-regarded scientists. Despite having a desire to join the military, his father refused any offer, and instead Guillemin worked with the PRAETORIAN Program, headed by Dr. Matthias himself. 
Guillemin became well-known for his mechanical understanding and knowledge of Covenant religion, language, and culture. In 2550, Matthias was killed by Covenant forces, and Guillemin immediately joined the military, first serving as an army mechanic and engineer, and later fighting on the frontlines near the end of the Human-Covenant War. 
=== Post-War ===
Following the end of the war in 2552, Guillemin was given special leave, and subsequently became the first graduate of the Athenian Academy of the Sciences in over a decade. Following this, he began developments of the PRAETORIAN Program, and personally saw the development and advancement of new technologies into the PRAETORIAN Guard. The foremost among these was the creation of a new type of neural link that allowed for users to remove their consciousness from a PRAETORIAN ZEUS suit, rather than remaining stuck within it as before. 
Thanks to his research and work, Guillemin was able to renovate the PRAETORIAN Program, and provide a much more reliable and safer use of ZEUS suits. He was made the chief scientist of the PRAETORIAN Program and served as a scientific adviser for the local military and Office of Naval Intelligence (ONI). During this period, he struck up a relationship with Dr. Karina Pine, an incredibly talented xenobiologist. 
=== The Testament Conflict ===
In the summer of 2558 Guillemin was overseeing ONI excavations of a Forerunner ruin on Athena, deciphering Forerunner technology to the best of his ability and studying their remnants. During this, the Testament of the Faithful, a Covenant splinter faction led by Lork Tonu, began raiding neighboring star systems, before launching a series of hit-and-run assaults in the early months of summer on Athena. 
On August 7, the Testament fleet entered into Athena space, and began a series of rapid attacks upon specific centers attempting to locate specific Forerunner relics. Over the next few days, the Athenian military would be quickly mobilized after initial strikes and engaged Testament forces. Guillemin's location was assaulted by a large group of Testament forces who captured Karina, though he escaped thanks to the arrival of the PRAETORIAN Guard and assistance from Jay-G084. 
Guillemin hooked up into his own self-designed new ZEUS suit, and properly armed boarded the UNSC frigate Rage Against the Dying, participating in the space battle against the Testament fleet. After a pitched fight, most of the Testament ships were destroyed though the UNSC naval forces received heavy damage and casualties. Tanu, aboard his flagship the Testament of Faith and a few other Testament space craft managed to flee from Athenian navy via special slipspace coordinates that were the target of the Testament's attack on Athena. These coordinates lead them to Installation 02, also known as the Epsilon Halo, on the far side of the galaxy. 
The Rage Against the Dying pursued the Testament forces, the only nearby undamaged UNSC military spaceship. Due to the Rage Against the Dying's slower slipspace drive, it took several days for them to arrive at Installation 02, finally appearing on August 18. Guillemin participated in the immediate battle against the Testament's forces, who had already begun establishing a new military base on Installation 02. Ultimately, the Rage Against the Dying would successfully bring down the Testament of Faith, thanks in part to Guillemin and an ad-hoc team of personal who boarded the ship. The Rage would suffer heavy damage and crash-land onto the ring's surface.
Along with Jay-G084, Guillemin helped fight off a small Testament attack, and the survivors of the crash established a temporary HQ on the ring. The UNSC and Testament forces would begin fierce fighting over the next few days. Guillemin participated in numerous missions that eradicated Testament military personal. Using his Forerunner expertise and with assistance from his personal AI Fey, 
On August 21, the UNSC forces were assaulted by a wave of Flood-infected species of native aliens known as the lliaggale, as well as bio-engineered Testament soldiers partially infused with Flood biology. Most personal were killed, and Guillemin fled alongside Jay-G084. They would meet with the native lliaggale, and after a tense and awkward initial meeting, came to an understanding with the aliens, who had been targeted by the Testament. They discovered that Tonu intended to release the Flood in a controlled case upon human space, in a zealous attempt to "wipe clean the slate from human stench" and build a new Covenant from the ring. 
Gathering a few remaining UNSC military personal and various lliaggale shoals, Guillemin and Jay-G084 lead an assault upon the Testament's fortress, located atop the Flood Containment Center. Fighting their way through hordes of Testament forces and Flood creatures, Guillemin was able to rescue Karina, who had been forced to research the Flood for Tonu as a potent weapon against humanity. He and Jay managed to get into the center chamber of the facility, and personally fought with a crazed and Flood-infected Lork Tonu, and after a tense fight killed him. 
In the aftermath, the remaining UNSC forces regrouped and began an extensive purging operation. Thanks to the assistance of the lliaggale and the monitor of Installation 02, 007 Contrite Witness, the Flood was quarantined and eventually exterminated, as well as any remaining Testament forces were wiped out. 
Over the next two months Guillemin and the survivors of the Rage Against the Dying were stranded on the ring. Guillemin personally oversaw the reconstruction and repairing of the ship, and thanks to assistance from 007 Contrite Witness and the lliaggale, were able to finish if by October 25. They departed and arrived back on Athena on November 2. However, by this time the Created Crisis had begun, and Athena was under tight lock-down by the Created. 
=== Resisting the Created ===
Guillemin, along with the rest of the Rage Against the Dying crew were captured by the Created. However, Jay-G084 managed to escape and rescue Guillemin. Both were betrayed by Karina, who allied with the Created to keep Guillemin's physical body safe. The two escaped however, and went underground. After hiding out, they managed to make contact with the Athenian resistance against the Created, and subsequently began a guerilla campaign against the Created, largely within the city of New Athens. 
Throughout the rest of the winter of 2558, Guillemin proved invaluable to the resistance, with his expertise in AI offering valuable insight into effective countermeasures. He typically joined Jay on specific target missions, including one to free imprisoned military personal. A later mission would rescue Karina and see the retrieval of his own physical body. Guillemin, with assistance from his AI Fey, managed to repair and rebuilt the DIANA Worldmind, a collective of AI designed to help run Athena's infrastructure, which began a digital war against the Created. 
Throughout 2559, Guillemin remained constantly on the run, and helping to direct the resistance efforts against the Created. A series of successful missions helped to weaken the AI infrastructure across Athena, and freed the PRAETORIANs from Created control, a major loss of the latter. By mid-Summer, the Athenian resistance had managed to openly rebel and free several cities across Athena, using anti-AI programs to disable Created control over these territories. Guillemin played a key role in developing these AI defenses and participated in many skirmishes throughout the fall. Conflicts began to increase across Athena, into winter, with open conflict between Created forces and reformed Athenian military. During this period, he proposed to Karina, and she excepted. 
On December 12, Cortana died in a three-way battle for Zeta Halo, and her death marked the end of Created control over Athena. The DIANA Worldmind was able to reassert control over global web, and over the next three months remaining Created cells and remnants were wiped out. 
In the aftermath of the Created Conflict, Guillemin set out to help prepare Athena for any future AI intervention, and went back to work as head of the PRAETORIAN Program. After the last remnants of the Created were wiped out, Guillemin and Karina married. 
==Personality and Traits==
=== Physical Appearance ===
Guillemin is relatively short, with green eyes and a slightly square face. He favors a small clean-shaven beard and combed hair, red in color. While smaller than others, he maintains a thorough workout routine, and thus is generally in excellent physical shape.
=== Personality ===
Guillemin is an introvert at heart, but deeply motivated. Losing his mother at a young age kept him close to his father, and Guillemin had few friends as a child. Guillemin remained a loner after his father's death, until he met Karina Pine. Even then, he still largely prefers smaller social groups, but cares deeply for those he trusts. Whenever they are threatened, he will move heaven and earth to protect those he cares about, and frequently throws himself into his work. Guillemin is generally very calm and polite at any given situation, and generally does not show a lot of emotion except around those he is close to. In rare occasions, his anger can boil over and he can lash out, though he often feels conflicted and guilty about this later. He is overall, motivated to protect his loved ones, determined to not lose someone he cares about again.
=== Religious Beliefs ===
Guillemin is largely agnostic, something he got from his father. His mother was a Neo-Baptist, but Guillemin has generally cared little for religion, except as an interesting case study. Over the years, he has grown more interested in belief itself, and generally accepts that something greater might be out there, he just isn't sure what it is.
==Skills and Abilities==
Guillemin's greatest attribute is his mind. He is widely regarded as an expert in alien and Forerunner technology, and possess a vast array of technical skills. Guillemin is widely considered a genius in his fields, largely the study and use of alien technology and mechanical engineering. He also has degrees in xenoarchaeology, xenoanthropology, and possesses extensive knowledge of the history of the Covenant and the Forerunners. Over the years, Guillemin has pursued further study into artificial intelligence and developed his own computer skills, which would prove vital during the Created Crisis.
Guillemin also has limited military experience, serving in the armed forces for two years after his father's death. This has given Guillemin basic military training, and he is capable enough to hold his own in a fight. In military engagements he usually favors sneaking behind enemy lines to disrupt them, using his very own PRAETORIAN carapace in combat.
==Relationships==
* Matthias Karly: Guillemin has high respect for his father, and was largely raised by him, but their relationship was somewhat strained in later years. After losing his wife, Matthias refused to lose his only son, and largely pushed him to pursue a career similar to his own, in order to keep his son close. Matthias also prevented Guillemin from joining the military. Despite this, the two were still close, and Guillemin was deeply hurt by his father's death, and joined the army to get revenge on the Covenant.
* Rebecca Karly: Guillemin lost his mother when he was five, but has fond memories of her as a child. He based the personality and appearance of Fey, his AI assistant, on her.
* Karina Pine: Guillemin's wife, he met her in 2554 when she joined the PRAETORIAN Program. They became fast friends, with similar fields of study and interest, and after a period of working together started a romantic relationship. Guillemin loves Karina deeply, and she has been his confident and support through many trials. Even when she helped the Created to keep him safe, he still continued to care for her.
* Jay-G084: Jay is Guillemin's best friend, and the two maintain a close relation built on trust and fighting alongside each other through many conflicts. Guillemin has saved his life more than he can count, and vice versa, and despite Jay's eccentricates, Guillemin trusts him with his life completely.
*Shala 'Vorom: A sangheili, Shala was the successor to Lork Tonu and the leader of the Servants of the Reclamation. She became acquaintances with Guillemin's father, and later Guillemin himself. While initially suspicious, Guillemin grew to respect her, and a friendship based on mutual respect developed. Shala helped Guillemin to see a different perspective of the Covenant and its alien members, and the two would retain cordial relations. Guillemin was hurt by her death during the Created Crisis.
