So first I want to say that I am glad you are all enjoying this story. And second here is the bio of Devin Cadman. Hope you all like it and be sure to review!

Name: Devin Cadman

Alias: Merlin Ambrosius, Spriggan, the Immortal Druid, Celtic Champion, Hero of the Faeries, Knight of Zero, Grandmaster of the Chivalric Order, the Druidic Knight, Devin the Damned, the Man born before Christ, the Strongest Magician, the First Magician, and the Oldest Human

Species: Human

Age: Unknown

Gender: Male

Background: Devin was born long before the birth of Jesus Christ in what is now modern day Scotland. He came from a tribe of humans who were Druids, people who could control the forces of nature and were considered an oddity even to the supernatural. Devin was the eldest child of the tribe's leader, and was seen as a prodigy in the arts of his people's magic. Along with being druids, Devin's people were also the ones who guarded the legendary Fountain of Youth, which was in the form of a goblet overflowing with the magical water. A single drop could heal any wounds and diseases, while drinking it grants the person eternal life. The druids had guarded the fountain since their beginning, protecting it from anyone undeserving no matter who or what they were, as well as protecting the local forest that grew from its magical properties.

During his late teen years, Devin's tribe was attack by Devils. The Devils were sent by the original Lucifer, who desired the Fountain's power to regain the powers he had lost after Satan took much of it away before being sealed. Devin and his people fought bravely, but were no match for the Devil's numbers and powers. During the battle, Devin had been fatally injured by a stray attack from one of the devils, which also killed his mother. In a desperate attempt to save him, Devin's younger sister and his lover took him to the Fountain of Youth, in hopes that its properties would revive Devin and give them a chance against the Devils. However in the event, Devin's sister was killed trying to protect them. Seriously injured and ignoring his pleas to save herself, Devin's lover forcefully made him drink the entire goblet before dying. Now revived and with his acquired immortality, Devin launched himself at the Devils, slaughtering them in a raging frenzy. During the fight, Devin awakened his Sacred Gear, Soul Thread, becoming its first wielder. In the aftermath, Devin was left as the sole survivor of the battle. Both the devil forces and his people were gone, along with the majority of the forest and the Fountain of Youth too. With nothing else to hold him there, Devin set out on his new immortal life.

Becoming a wanderer, Devin began to travel the world and discovered many new cultures as well as expanding his magic. Going under the alias of Merlin Ambrosius, Devin began to discover and master multiple forms of magic, creating thousands of spells and magical items too. After researching the demonic powers and magic of Devils, he began teaching magic to other humans, writing spell books for his students to pass onto others. He also taught them how to harness the magical powers of other mythological factions such as the Norse and Faeries. However very few could learn and master Druidic Magic since many did not have a strong connection to nature like Devin had. Eventually, Devin's actions resulted in the creation the magic system that the magicians of today use, where they now employ hundred forms of magic from different factions. He saw this as a way of giving humanity something to protect themselves with against the supernatural. Devin also began training in using his Sacred Gear, eventually achieving Balance Breaker and creating a sub-species Balance Breaker. After defeating several Celtic Gods, and earning their respects, Soul Thread became one of the few Sacred Gears that could kill Gods. Devin also befriended the Faeries, sharing in their love for nature and protected forests all over the world. He also took up the title Spriggan, regarding it as an ugly name that was well deserved for someone as cursed as him.

Sometime during the Great War, Devin returned to the isle of Britain where he met a young Arthur Pendragon. Taking an interest in the young boy, Devin befriended Arthur and guided the young man when said person was chosen by Caliburn to become the next King of England, and later on taught Arthur how to use Excalibur. Devin also made extensive research on both Holy Swords and Demonic Swords, trying to figure out how humans could use them to fight against Devils and Angels. Arthur also became one of the few people who learned of Devin's immortality and merely shrugged it off like it was no big deal. That merely solidified the close friendship the two had and Devin became a loyal adviser to Arthur afterwards. During his time in Arthur's court, Devin took in an apprentice named Morgana le Fay, and she became one of his best and well known students, alongside the Gallic Druid, Diviciacus.

It was around this time he met Trihexa, who had just been given his powers back by his wife Elaine. Despite having been a Devil, Trihexa and Devin seemed to have developed a trust of friendship, since both despised Lucifer and are also both outcasts due to circumstances out of their control. Due to this, Devin formed a pact with Trihexa, becoming the first magician to form a pact with a devil. Thanks to Trihexa, Devin made the discovery of the Celtic Sword, Claiomh Solais and took it as his own, discovering his own holy energy within him.

At an undisclosed time, Arthur consulted with Devin about his fears for Excalibur after his death. Arthur worried that after he was gone, other forces may try to get their hands on the powerful Holy Sword and use it for dark deeds before it could be returned to Vivian, the Lady of the Lake. The King was also very wary of the Church as he was not blind to the organizations fanatical and prejudice views towards anything against their religion. However Arthur was killed in battle and the sword was destroyed by an unknown being. The fragments were taken by the church, where alchemists created seven different Excalibur fragments. Enrage at this desecration, Devin stormed the place where the fragments were being held. Despite his efforts, Devin only manage to retrieve Excalibur Ruler, the strongest fragment, and the sword's sheath, Avalon, with him. However he swore that one day he would re-forge the blade and return it to the Lady of the Lake, fulfilling Arthur's promise. Devin also held onto Caliburn but under Vivian's request, gave it to the Pendragon Family for safekeeping. But he held onto Avalon and hid Excalibur Ruler away until the time when he could make Excalibur whole again came and return it to Vivian, fulfilling Arthur's promise.

The next several centuries are unknown, besides Devin dealing with the Witch Hunts, helping magicians and innocents from being killed by fanatical Christians and Exorcists. He has also has had several encounters with Ophis, the Infinite Dragon God. 200 years ago Devin, reluctantly at first, took part in helping the Anti-Satan Faction win the Civil War against the Old Satan Faction. He had been sought out by Sirzechs, Serafall, and Ajuka, the young devils at the time needing to something or someone to give their side an edge in order to stop the descendants of the old Satans from attacking Heaven and rendering the Devil race extinct. After helping win the civil war, Devin had to deal with a persistent Sirzechs who wanted to have Devin join his peerage. Eventually Devin managed to end the whole thing by defeating Sirzechs in combat with Grayfia as the spectator, thus Sirzechs stopped trying to persuade Devin to become his Bishop.

Devin also took some part in World War 2, freeing concentration camp prisoners and helping defend Britain from the Nazi forces. It was at that time Devin formed a brief relationship with the Queen of England and became an honorary member of the Chivalric Order, an organization of knights founded by Arthur, Devin and the Knights of the Round Table, dedicated to the protection of mankind. He also became the Order's Grandmaster, gaining the rank as Knight of Zero. Later on he cared for a pair of young Nekoshou sisters, naming them Kuroka and Shirone and teaching them about Senjutsu, which was an art similar to druidic magic. Recently Devin took in Yasei, a very young male Nekoshou that Devin found as an infant, his parents killed by Devils due to Kuroka killing her Devil Master. Knowing the truth of Kuroka's actions, and disgusted by this act of genocide, Devin personally hunted down every Devil who partook in the slaughter and brutally killed them. Eventually Sirzechs, not wishing to make an enemy out of someone like Devin, managed to stop the genocide and also take in Shirone, Kuroka's younger sister. Currently Devin is now acting as a mercenary for both the human world and supernatural world, while also raising Yasei until he is old enough to take care of himself.

Appearance: A tall young man with a lean muscular build. Has bluish-gray hair and brown-orange eyes. He has multiple Celtic tattoos on his body, from his back, chest, shoulders, arms and legs. His usual attire consists of a green jacket that has a grey interior and hood. Underneath the jacket he wears a sleeveless navy blue shirt. Over his hands are usually maroon fingerless gloves. For the lower part of his body he wears grey jeans and black trench boots. He normally wears a basic version of the Chivalric Order's symbol, which is a silver shield with two swords behind it, crossing each other, and the number zero engraved on it, signifying his rank. It is attached to a chain necklace.

Personality: Stern, serious, speaks casually, polite but blunt, mild-sadistic, and is sympathetic to those with similar problems like his.

Likes: Nature, magic, research, animals, people with open minds, new ideas, inventing, learning new culture, and traveling

Dislikes: Devils affiliated with the Old Satan Faction, God, and the Church, and Witch Hunters, people who claim to be immortal, arrogant people, tyrants, large urban areas, pollution, and slavery

Abilities:

Master Magician: As the first human Magician and developer of the current magic system, Devin is the strongest Magician in existence, having been dubbed a prodigy by his tribe. His magical powers exceed that of many supernatural beings such as Devils. Due to his immortality and incredible talents, Devin has a wide range of knowledge on all forms of magic. This includes Druidic Magic, Black Magic, White Magic, Alchemy, Elemental Magic, Norse Magic, Faery Magic, Demonic Magic, Dragon Magic, Elven Magic, Fallen Angel Magic, Angelic Magic, and various Forbidden Spells, and much more. He has also developed thousands of his own unique magical seals and formulas, many unorthodox, and can cast spells in a short amount of time with little trouble in any language (i.e. Latin, Irish, Scottish, Japanese, Chinese, German, Norwegian, or Greek). Also since being the first magician, Devin is capable of using nearly every spell in existence, along with negating or absorbing the spells due to his incredible understanding of magic. Furthermore many of his spells are of his own making, thus only he can use them. He calls these spells "Tier Spells" ranking from 1 to 10, higher the number greater the power. Along with that he created spells he deemed "Super Tier Spells". According to him those spells are meant only for powerful combatants.

Druidic Magic: Despite knowing different Magical arts, Devin's strongest one is Druidic Magic, his Celtic Origin. Like Senjutsu Users, Devin can absorb and manipulate the energies of nature. However unlike them, Devin can manipulate all of nature and the weather too, without fearing of the effects of being driven mad by malice. His prowess with Druidic Magic are so great he can change the environment and weather at will to the point he is capable of causing natural disasters. He also possesses incredible dowsing and healing abilities and Devin is also capable of communicating with animals too. Finally, Devin can channel natural energy through him similar to Senjutsu users and also developed a way to convert it into holy energy to empower his Holy Sword.

Immense Magical Powers: Having been taught magic since birth, and being born into a tribe of Druids, Devin has incredible magical powers. His powers have only increased over the years and are above Satan Class level as he was able to fight and defeat Sirzechs Lucifer, one of the three devils labeled as Super Devils. Furthermore his skills as a Magician outweigh far more than the standard 2 Bishop Pieces of the Evil Pieces. Similar to Devils with their Demonic Power, Devin can also release his magical energy. When emitted, Devin's magical powers can paralyze many powerful combatants and a single burst of magical power is enough to cause considerable damage to both people and structures. The shockwaves can even deflect oncoming projectiles too.

Weapons Expert: Though not his area of expertise, Devin has great skills with a variety of weapons, especially swords such as Claiomh Solais despite not taking it out unless he is force too. Due to knowing Alchemy and thus the ability of transmutation of matter and elements, Devin can create weapons such as swords, spears, axes, knives and chains. Devin can also infuse his magic spells with his weapons to give them unique attributes.

Immortality: Another of Devin's greatest abilities (or curse as he calls it) is his immortality. After drinking the entire contents of the Fountain of Youth, Devin has gained eternal life and thus cannot die. Not only that but Devin also has superior regenerating factor, meaning any wounds, no matter how serious, heal in just a matter of seconds. Even if his entire form was disintegrated, Devin would merely reform his body in just a few minutes. Unlike the Phenex Clan, whose regeneration abilities rely on the amount of demonic power they have, and their mentality not being broken, Devin's works on its own accord and is not affected by any other source. This also grants him immense durability and nigh immunity to pain. Another fact is that Devin requires neither food nor oxygen to live and is immune to all forms of poison, no matter how complex they are, as well as other foreign matter (i.e. like Evil Pieces). In truth, the only way to defeat Devin is to render him unconscious or bind him, though the latter must be powerful as Devin would be able to break free of it using his physical strength or magic.

Hand-to-Hand Combat Expert: Though not the prefer form of combat used by Magicians, Devin is highly skilled at fighting up close. Having traveled the world for so long, Devin has gained an immense amount of knowledge of different fighting styles. He incorporates them with his magic, to augment his strikes and make them more deadly. The Celtic tattoos on his body are what he uses to channel magical energy through him, so that his physical capabilities will increase.

High Intelligence and Intuition: At a young age Devin was already considered a prodigy. His incredible intellect, Devin was able to master multiple arts of magic with ease and able to teach them to others. Devin also has great understanding of other people's powers, fighting style, strategies, and goals by merely taking a glance at them and figure out ways to counter them. He also has a strong intuition of magical spells, able to figure out how they work just by hearing the incantation or runes of the spells, easily able to master the spells in short notice during battle.

Supernatural Condition: Because of his immortality, magic and millennium of training, Devin's body is beyond normal human beings, even Sacred Gear wielders. His strength and speed are top notch, capable of overwhelming an enemy without giving them time to react. His endurance and durability allow him to cast spells without tiring and survive more powerful attacks with little trouble. Devin trains his body every single day as to help him keep up with his magical prowess and that a Druid must always be physically fit.

Equipment:

Claiomh Solais: The Celtic Holy Sword that rivals Excalibur, Caliburn and Durandal, Claiomh Solais also known as the "Sword of Light", is a sword that Devin discovered during his return to his homeland. He later took the blade as his own. As a Holy Sword, Claiomh Solais is capable of killing Devils, and is capable of slaying Ultimate Class ones. Claiomh Solais emits a powerful bright and burning light from the blade, becoming stronger depending on the wielder's holy energy that is infused into the blade and can be manipulated in various ways by the wielder. At full power the blade can incinerate whatever it touches from existence as well as capable of blinding people. The light can also cover Devin like armor.

Soul Thread: Devin's Sacred Gear is called Soul Thread, or The Hands that Binds and Sever. It was activated when he fought against the Devils that attacked his tribe. It takes the form of a pair of black fingerless gloves and silver thimbles over the ends of the fingers and thumbs. Running across the back of the hands are sea green strings that look like veins. The strings are near invisible and their length is unknown except to Devin. The threads are also very durable and sharp, being unbreakable and can cut through anything, even space and the intangible, with ease. Devin can manipulate the threads like an extension of his own body and use them for multiple purposes like controlling peoples' bodies. He can also infuse his magic into the threads to increase versatile with them. Also Devin's constant training has allowed him to generate more than one strand of thread from each finger, the maximum being twenty per finger, as well as regenerating them if they are somehow broken. Soul Thread is actually capable of killing gods and is on the same level as the Longinus but was never ranked as one officially due to Devin remaining in the shadows.

And there is Devin's bio. I hope you all enjoy this and realize how much of a badass Devin Cadman is. Be sure to review and remember, I hope people start making their own Trihexa stories. Also if you noticed I changed the one shattering Excalibur from Tristan to a third party since it is for future chapters.
