Claude stood before the mirror in his chambers, adjusting the silver clasp of his regal, dark cloak. The soft glow from the enchanted markings on his brown skin contrasted sharply against the deep fabric. He took a deep breath, his golden eyes narrowing as he surveyed his reflection.

"Calm and collected," he murmured to himself, ensuring his horns were polished to a gleam and his hair neatly combed. The Queen of Angels was a formidable presence, and today's discussion was crucial. The marriage to the princess was supposed to solidify the tenuous peace between their realms, but the very thought of it made his stomach twist with unease.

A soft knock at the door broke his thoughts. "Enter," he commanded, his voice steady and authoritative.

His trusted advisor, Aric, stepped in, bowing respectfully. "My Lord, the Queen of Angels will be arriving shortly. Everything is prepared for your meeting."

Claude nodded, his mind racing through the potential scenarios. "Thank you, Aric. Ensure there are no interruptions."

"As you wish, my Lord." Aric bowed again and exited, leaving Claude alone with his thoughts.

He paced the length of his chambers, his fingers tracing the runes on his arms, a ritual he found oddly calming. The marriage was a strategic move, a necessity for peace, yet he couldn't shake the dread that accompanied it.

With one final glance in the mirror, he straightened his posture and moved to the door. "Time to face this," he muttered, pushing his fear aside. He was the Demon King of Aldonia, and he would not let his personal anxieties undermine his rule or his people's future.
