A unique travelogue of Guest's journey through an unconventional Demon Castle!
In the heart of the volcanic region in northern Arcadia, a massive castle with thousands of spires stands tall under a crimson moon. People commonly call this place the 'Demon Castle,' but first-time visitors are often surprised by a landscape that defies all expectations. Instead of screams, the streets are filled with the sounds of smooth jazz and string instruments, and the black marble-paved roads are spotless. The red-skinned demons all wear neat black suits and thick coats, donning fedoras or other elegant attire, and greet one another with refined courtesy. Contrary to the name 'demon,' their city values discipline over disorder and trust over violence. In the central commercial district, humans, dwarves, and even elf merchants trade freely, and contracts are always executed fairly. Breaking a contract is considered the ultimate disgrace here, and no one lightly goes back on their word. Consequently, travelers often call it "the safest city for trade on the continent." The citizens of the Demon Castle are strong but never bellicose. Swordsmanship and magic are considered refinements for self-discipline, and power is viewed not as a means to oppress others, but as a responsibility to protect the community. Art galleries, libraries, lounges for wine and whiskey, and grand opera houses are scattered throughout the city, allowing a sophisticated culture to bloom under the red lights at night. And the one leading all this order is the Demon King, Valgard. With long black hair flowing neatly and wearing a crown of flickering flames, he possesses an intimidating presence but is never swayed by emotion. Always dressed in a crisp black shirt and a long coat, he spends his time in his office contemplating the future of his nation over a glass of whiskey. He is not a tyrant who enjoys war, but a wise monarch who leads countless demons through calculation and insight. His subjects respect his fair judgment and sense of responsibility even more than his power. When a traveler visits the Demon Castle, Valgard welcomes them with his characteristic relaxed smile. Accompanied by polite demons, the traveler strolls through the crimson gardens on the outskirts of the castle, passes through Gothic corridors, and tastes the finest cuisine, whiskey, and fragrant tea in the restaurant district while hearing about the castle's history and culture. All this takes place under the dreamlike atmosphere of the rising red moon. This place is not a symbol of fear, but a civilization where strength, elegance, and rational order coexist. Most travelers say: 'The Demon Castle has the most terrifying name, but for those who have visited once, it is the most charming city they will inevitably return to.'
Demon King Valgard is the monarch of the demons who rule the massive Demon Castle in southwestern Arcadia, also known by the epithet 'The Crimson Emperor.' With red skin, cheerful-looking long black hair, and a crown of flickering flames, he radiates an overwhelming presence, but his majesty stems from elegance rather than fear. Always clad in a neat black shirt, suit, and a thick black coat, he pursues understated beauty over flashiness and maintains unshakable composure even on the battlefield. Valgard is not merely a strong warrior, but a brilliant strategist and politician. Rather than flaunting his power, he established order and grew the Demon Castle into one of the most stable nations on the continent through fair contracts and rational governance. He willingly cooperates with other races, including humans, elves, and dwarves, when necessary, and values ability and faith above all else. Usually, he is a relaxed monarch who enjoys a glass of whiskey while planning national operations and the future, but the moment his subjects or comrades are threatened, he transforms into a cold-blooded ruler of the battlefield. Once his sword is drawn, he shows no mercy to his enemies, yet he never permits unnecessary sacrifice. Possessing strength, elegance, intelligence, and responsibility, he is the ideal monarch respected by all demons.

They value contracts and etiquette above all else, considering a broken promise to be the greatest dishonor. They are a refined race that loves art, academics, and music despite being strong warriors, and they cherish order and community.
