Background

Arthur was the biological son of a king but was raised away from the castle by Merlin, who provided him with a comprehensive education and personally tailored his training. More than a decade of uninterrupted training made him far stronger than ordinary people before he reached adulthood. 27

Merlin arranged for Arthur to accompany Ethan on interplanar journeys so that he could broaden his horizons before assuming the throne. Arthur eagerly accepted the opportunity, viewing unfamiliar worlds, technologies, and cultures as valuable preparation for kingship. 24 29

During their voyage through the Sea of Tranquility, Arthur became Ethan's first companion. He trained Ethan daily, sparred with him, fought alongside him against hostile sailors, and learned a new language through Merlin's knowledge-sharing amulet. 27 31 37

His exposure to people such as Diana and to powers beyond his own changed his ambitions. Rather than pursuing personal strength above all else, Arthur concluded that becoming an outstanding king mattered more than becoming a demigod-level warrior. 61 65

After roughly a year of travel and growth, Arthur returned to his world to prepare for the throne. He and Ethan parted on good terms, each expecting that they might meet again. 98 99

Appearance

Arthur was a blond youth during his travels with Ethan, later growing into a tall, handsome man with the composed presence of a mature king. 29 412

• Originally wore long golden hair, which he cut short for practicality while sailing; a stubborn tuft remained noticeable afterward. 29
• Was already tall and powerfully built for his age due to Merlin's training. 27 31
• As king, he was described as warm, refined, and fitting the popular image of the legendary King Arthur. 412
• Carries the Sword in the Stone at his waist as a symbol of royal authority. 412

Personality

Arthur was initially sunny, curious, and eager to test himself against strong opponents. His knightly ideals made him hesitant about ambushes and preemptive violence, but he was thoughtful enough to recognize the dangers of allowing enemies to dictate the terms of a conflict. 31 35

Traveling with Ethan made him more reflective and pragmatic. He retained his desire for strength, yet came to see martial ability as one tool among many rather than the defining quality of a ruler. 61 412

As king, Arthur is patient, diplomatic, and approachable despite his rank. He treats guests with warmth, earns loyalty through personal charisma, and is capable of decisive military action when he detects a threat to his kingdom. 412 413 617

Abilities & Skills

Swordsmanship and Combat Training

Arthur received over ten years of systematic training from Merlin and was already a superior fighter as a youth. 27

• Defeated Ethan in their early sparring match through superior training. 27
• Held defensive positions effectively during shipboard combat and coordinated seamlessly with Ethan. 31
• Continued developing combat techniques even after becoming king, though prolonged peace left him with few chances to use them. 412
• Recovered toward his former peak combat condition after accepting a rejuvenation potion, though he required time to regain his full fighting ability. 766

Kingship and Strategy

Arthur applies knowledge gained from other worlds to statecraft, infrastructure, and military expansion. 413 614

• Built Camelot with planned residential and market districts, modern-style drainage, and sewage systems. 413
• Prioritized sanitation, food supply, and living standards during the difficult early years of his reign. 413
• Unified Britain through direct annexation rather than relying on the allegiance of separate kingdoms. 413 614
• Mobilizes overwhelming force against suspected conspiracies rather than allowing threats to develop unchecked. 617

Magical Knowledge

Arthur practiced magic and other abilities discussed during his travels with Ethan, though he had limited opportunity to use them while governing a stable kingdom. 412

• Received magical equipment and blessings from Merlin before leaving his home world. 29
• Used Merlin's knowledge-transfer amulet to overcome a language barrier. 37
• Maintains enough magical knowledge to use the teleportation arrangement between Camelot and Merlin's residence. 412

Equipment

• Sword in the Stone (Caliburn) — Arthur's royal sword and symbol of kingship; unlike the legend Ethan knew, it remained intact throughout Arthur's reign. 412
• Merlin's longsword — A powerful weapon given to Arthur after he transferred the Sword in the Stone to Mordred upon her succession. 766
• Silver Light Armor and blue battle robe — Equipment supplied by Merlin for Arthur's early travels. 29
• Two-handed broadsword — A weapon over 1.2 meters long carried during his voyage with Ethan. 29
• Sea blessing — A spell cast by Merlin that ensured Arthur would not drown. 29
• Knowledge-sharing amulet — A small metal amulet from Merlin's collection that enabled the transfer of language knowledge into Arthur's mind. 37
• Personal terminal and storage space — Provided by Ethan after Arthur's abdication, allowing him to carry belongings and study modern knowledge while traveling. 766

Relationships

• Merlin — Guardian, teacher, and political supporter. Merlin raised Arthur, trained him from childhood, and sent him across worlds to prepare him for rule. 24 27
• Ethan — First interplanar companion and longtime friend. Their early travels reshaped Arthur's worldview, and they remained close through reunions, Arthur's reign, and his abdication. 29 99 412 766
• Diana — Former swordsmanship student and longtime acquaintance. Arthur trained her on Themyscira before later recognizing her as the grown demigod she had become. 61 412
• Guinevere — Queen of Camelot. She openly admires Arthur and shares a close relationship with him. 413
• Mordred — Arthur's daughter and eventual successor. Arthur acknowledged her after Morgan's spell produced an unexpected outcome, ensured she was raised and educated, and ultimately abdicated in her favor. 414 765 766
• Bedivere — Loyal Guard Knight who remains ready to protect Arthur and monitors his welfare. 413
• Artoria — A parallel-world counterpart of Arthur. Ethan brought her to Camelot so that Arthur could guide her through her doubts about kingship. 614 615

Reign of Camelot

Arthur transformed Camelot into a clean, highly organized city that surpassed the standards of its era. While technological limits prevented him from realizing every modern design he had envisioned, the city possessed planned districts and advanced sanitation infrastructure. 413

He expanded his kingdom by building internal strength before annexing neighboring realms. His success attracted capable followers and strengthened the Knights of the Round Table beyond their legendary reputation. 413

Arthur also responded differently to the fate associated with his legend. He preserved the Sword in the Stone rather than allowing it to break, treated it chiefly as a royal symbol, and focused on establishing a durable kingdom instead of relying on individual martial supremacy. 412

Succession and Later Travels

Arthur accepted Mordred as his child and had her raised rather than abandoning her after Morgan's disrupted spell changed the expected outcome. 414

After decades spent building his empire, Arthur concluded that he could not perfect it himself and chose to abdicate, leaving Mordred to improve upon his work. He accepted a potion from Ethan and Merlin that restored his peak age and health, then transferred the Sword in the Stone to Mordred. 765 766

Freed from the throne, Arthur began preparing to explore other worlds and expressed particular interest in seeing the wider universe. 766
