Yurnero

In the canon, Yurnero the Juggernaut, named after the martial tradition that he swore to preserve and protect, is the last of his masked kind who drowned beneath the waves that deluged the ancient Isle of Masks. While his inanimate mask bears no readable expressions, each motion of his blade arm is an expression of a lost art that yearns to be remembered, and every ritual that he casts alone is but a shadow of the Isle's once lively and rich traditions. No one has ever seen the face hidden beneath the mask of Yurnero the Juggernaut. It is only speculation that he even has one. For defying a corrupt lord, Yurnero was exiled from the ancient Isle of Masks--a punishment that saved his life. The isle soon after vanished beneath the waves in a night of vengeful magic. He alone remains to carry on the Isle's long Juggernaut tradition, one of ritual and swordplay. The last practitioner of the art, Yurnero's confidence and courage are the result of endless practice; his inventive bladework proves that he has never stopped challenging himself. Still, his motives are as unreadable as his expression. For a hero who has lost everything twice over, he fights as if victory is a foregone conclusion.
Pre-Banishment Yurnero had to earn his skill to become the master swordsman that he is today. He once trained under the tutelage of his late swordmaster (of whom we don't know the name of) until he became a swordmaster just like him. His master rewarded him with a traditional hakama and the sword Akakiryu which got its name from a legendary dragon.
Long ago, Yurnero took it to himself to retrieve the Defender, a greatsword that stolen from the Ivory Isles. He slew its thieves and now wields the Defender with honor.
Yurnero is a successful hunter with many kills under his belt, including demons and abominations, with a few of them possessing an alien hunting intellect. He was noted to have slain a brave beast with large tusks in a fierce battle and killed a mountain wolf with open handed strikes. He may have slain a single member of the now extinct corodont species, carving a mask out of its ivory heart.
Banishment Although the original account tells us that Yurnero was exiled and banished to sea for his defiance against a high lord, there is another account of Yurnero's banishment. Upon his exile, he was fitted with a mask that symbolized his status as a Ronin with no master to guide him, which differed in appearance from his default mask that we are all familiar with.
It's implied that Yurnero's exile happened for another reason besides his defiance against a corrupt lord. The context behind his insubordination was that he may have been complicit in defending the dishonored unmasked outcasts of the Isle of Masks. These wretched folk got their punishment from violating a creed or another. Their retribution was to be stripped of their honor and masks, and cast away from the reaches of society so that they may never again influence the affairs of the Isle. Defending these people even in the face of highborn defiance will elicit exile away from the Isle itself, the very same fate that Yurnero was inflicted with.
The Sundering

In an unspecified event, possibly a duel, Sven cleaved Yurnero's mask in two with the Adjudicator's Blade, cracking its top and awakening the ancestral souls that laid dormant inside it. Among the spirits was an ancient dragon, who now accompanies Yurnero and contributes his powers to him. Thus, the Juggernaut became a being merged from many souls. The dragon's might, combined with the great strength of his ancestors, made him more powerful than ever before. Yurnero and his dragon are grateful for Sven's actions, and feel they owe Sven a debt of gratitude.
After the sundering, the Juggernaut and his dragon planned to restore what they have lost. Once the Ancient is destroyed, they vowed to bring back their people and begin the rebirth of the Isle of Masks.
Personality and Mannerisms

• It is said that Yurnero doesn't feel sad for what he has lost, for he is implacable and purges that grief with a pursuit for honor. However, he sometimes broods over something that he has lost, which might be his beloved Isle or his lost relationship with Lanaya.
• When engaged in battle, Yurnero lets all of his fury out on his foes.Despite this, he stands between black and white to become grey–being emotionally distant and not even revealing his other emotions and thoughts to anyone, reserving nothing to others but his sword and hand.
• Even after the destruction of his Isle, Yurnero still adheres to the Isle's culture that revolves around honor and respect. He respects worthy opponents who die by his hand(sometimes preserving their remains as his memento of the honor that they have) and lets them know that their deaths are honorable. He has no respect for cowards, and anyone who engages in acts of cowardice.
• Yurnero is a brave and courageous warrior, a result of his faith in the endless practice and refinement of his craft. It's one thing to face dangers and adversity without fear, but he knows that there is a clear boundary between being brave and being foolish. He was brave enough to defy the last lord of the Isles whom he believed was corrupt, and he defended the dishonorable outcasts of his island home, in spite of the knowledge that defending these people in the face of defying the authorities will grant him a fate far worse than what these outcasts have. He doesn't fear death, but he certainly prefers to steer clear from it. Sometimes, he relies on alcohol to get a boost of courage.
• Yurnero is a confident swordsman, the result of his faith in the endless practice and refinement of his arts. Perhaps it can be said that his conviction in his ability is what makes his bravery different from foolishness. This is reflected in his use of weapons that are deadly to the wielder and its target.
• Yurnero often celebrates battles with a banner that he carries on his back. He believes that a battle is no good if there's nothing to celebrate it.
• A stern and serious warrior, Yurnero practices and values discipline.
