Artorias

The fabled hero Artorias, the Abysswalker, was a man who served as an X-Grade Mercenary for the Axis, before his defection. Renowned for being invincible, the fastest man in history, and for his multitude of grandiose adventures, Artorias is considered one of the most powerful individuals to ever walk the planet. His multiple exploits are often relayed as legends and fairytales, though most stories are factual in origin. He is one of the few people believed to be on par with the Silver Blade, James Consumit, and is considered by many to have been a Chosen One.

Backstory
His birth prophecized long before his conception, Artorias was born to a widow with no love for him, and so he was thrown out into the wilderness. The Goddess of the Moon and Sea, took pity upon the child - raising him herself until he grew to be seven years of age. Teaching him how to survive, and how to unlocking the rare Godly Ki within him, the Moon Goddess sent Artorias out to join civilization. It was at this point that Artorias, with a mind of his own, stumbled upon the town of Londome.

The residents, impressed deeply by the boy's resilience in finding their town, took it upon themselves to help raise him. Adopted by a blacksmith, at the age of 10 Artorias was allowed to learn of the demonic wolf that preyed upon the town.

Every new moon and blood moon, a white wolf, said to be the size of a horse and with an impenetrable cover of fur, would feast viciously upon the livestock of the town. "A beast with fur as pale as the moon, whose silver eyes can petrify any who stare too long, whose breath brings forth hell's very flames, can not be killed, cannot even be injured - all it may and can do is terrorize every new coming of the lunar cycle, and every dreadful crimson eclipse."

All warriors who tried to fell the beast met grizzly ends, unable to even deter it from their home. It was at this point that Artorias, despite the many protests, vowed to slay it. His father eventually relented, citing that Artorias was the most promising warrior he had ever seen, with a premise that rivaled the great Caesar. Artorias sat on the roof of a chapel, holding a spear his father had crafted for him, alongside two broadswords, and a bow fashioned from crimson oak. The bleak darkness of the new moon fell upon the town, and soon enough, the gallop and bounding of the great white wolf came upon the town.

Artorias, with his bow, attempted to shoot down the beast - only to watch as his arrows hopelessly broke in two upon contact with the beast's hide. A voice whispered to him to aim for the eyes, and so he did - but the harsh gale and the speed of the beast prevented any solid hit.

With his last arrow, it is said the Sun God himself guided Artorias' shot, as he released the bowstring the arrow shot forth with golden light, piercing into the right eye of the beast. Letting out a great howl of pain, the wolf staggered as Artorias capitalized on the opportunity - leaping down in front of the beast. Turning it's gaze towards Artorias, Artorias made promise not to look it in the eye - and a vicious battle ensued.

After the field was set ablaze with the wolf's breath, and upon the loss of both of his broadswords, Artorias grazed the wolf on it's nose. Never facing such before, the wolf retreated into the night. Determined not to fail, Artorias followed the beast with frightening dedication - stumbling upon the den the wolf called home. Figuring by this point that only it's fur was impenetrable, Artorias chased down the vicious beast, killing it by running his spear up through the roof of the canine's mouth. Afterwards, Artorias found a litter of wolf cubs - and, feeling remorse for having slain their parent, yet knowing they would only cause more problems in the future, slayed all but two - gifting one to the lord of Londome and keeping the other as a companion, before naming it Setanta, after his adoptive father.

Trivia

 * Artorias name and alias, the Abysswalker, are both derived from the character of the same name in the Dark Souls game series. The original Artorias was a renowned knight of the First Lord Gwyn, having a great white wolf companion named Sif.
