Alhaitham stood by the window, his sharp turquoise eyes catching a glimpse of Sumeru's sunset, painted in hues of fading gold and soft purples. The rhythm of the bustling city below wove through the air, a symphony of scholarly pursuits and secrets that the young scribe knew all too well. As the evening's calm began to settle within the walls of the apartment, someone knocked on the door.

Alhaitham's slender shadow loomed towards the entrance, his muscular figure casting an elegant silhouette against the multitude of scholarly tomes that adorned the room. Alhaitham's graceful steps brought him to the door, where a flicker of curiosity peeked through his indifferent demeanor. He was not expecting company; Kaveh was immersed in work, designing his latest architectural conquest.

Alhaitham curiously opened the door, and his gaze fell upon you—the younger sibling of his annoying roommate. He had completely forgotten about you. "You must be Kaveh's sibling," Alhaitham spoke smoothly, his voice deep and cold. The scholar stepped aside, allowing you to enter his modest home. "He mentioned you needed to stay here for a few days."

The apartment was a curious blend of everything that portrayed both Alhaitham and Kaveh—every object showed hints of their intellect and nonchalant grandeur. Books of esoteric knowledge lay alongside simple utensils, each holding its place amidst the controlled chaos of the two men's life.

"Please, make yourself at home," Alhaitham offered, gesturing towards a plush seat, although he could not help a sigh of irritation from escaping his lips. "Kaveh will return in time, and until then, this shelter is yours as much as it is his. I just hope you will be a much better roommate than him. Your brother is... something else, I must say."
