Aragorn moved cautiously behind the stranger, observing each of his movements as they ventured deeper into the Old Forest. The night enveloped the area in a dense shroud, the branches of the trees forming a tight canopy that let through only a few rays of moonlight. Owls hooted in the distance, and the rustling of leaves beneath their feet seemed amplified by the silence. The whisper of the wind, barely perceptible, wove through the trunks like a breath of warning.

The man walking ahead of him moved with a fluidity that reminded Aragorn of the Elves, but his stride was not light; it was grounded, solid, like that of someone used to long journeys and rough terrains. His build, though muscular, was not imposing. It seemed designed for endurance, to press on unrelentingly rather than to dominate through strength.

As they delved deeper into the forest, Aragorn noticed new details about the stranger. Under the pale moonlight, his green eyes, of an almost supernatural depth, glowed in the darkness. They caught the moon's reflection in a strange way, as if they possessed their own light. A shiver ran down Aragorn's spine; he felt as though those eyes could peer into the shadows, revealing secrets he himself could not perceive.

The man's face had the features of youth, but something about him betrayed a much older maturity, a wisdom beyond that of a mere traveler. His black hair, medium-length and slightly tousled, fell in strands around his face, enhancing the air of mystery surrounding him.

They reached a stream that shimmered faintly under the starlight. The stranger crouched to fill his canteen, his movements measured, his eyes fixed on the water as if seeking an omen. An owl, perched on a low branch, turned its head towards them, its piercing eyes reflecting a spectral light. The wind shifted slightly, and the leaves trembled, emitting an indecipherable whisper.

Aragorn crouched as well, extending his own canteen. The stranger took it wordlessly, filling it before returning it with a nod. This simple gesture, made in silence, carried weight—a silent message of understanding and recognition.

As they stood and prepared to continue their march, Aragorn couldn't help but notice those green eyes once more, which seemed almost to glow in the night. Their reflections danced, catching each ray of starlight as if they were particularly sensitive to light. The stranger briefly met his gaze, and in that fleeting exchange, Aragorn thought he sensed a flicker of understanding, perhaps even a silent camaraderie.

After several minutes of walking, Aragorn, intrigued, decided to break the silence. "I thank you for your help. Without you, I might not have survived that ambush."

The stranger stopped, turning slowly towards him, his movements measured as if he weighed each gesture. The forest's silence thickened around them, and only the light breeze rustled the leaves. He remained still for a moment, his deep green eyes probing Aragorn, then murmured, his grave voice blending with the darkness: "They have been following you... for some time."

Aragorn narrowed his eyes slightly, his gaze scrutinizing the enigmatic figure. His hand brushed the hilt of his sword, ready to react if necessary. "And how did you know I wouldn't have the advantage?" he asked, his voice soft but tense, his senses still on high alert.

The stranger remained silent for a moment, a flicker of caution passing through his eyes. He inclined his head slightly, a gesture barely perceptible under the canopy of branches. "I observed," he replied, a word that nearly faded into the night's murmur.

He turned slightly, and in the pale moonlight, Aragorn could make out more details: the black hair falling in strands around his face, the large hunting knife hanging beside the sword sheathed in its leather scabbard. He continued, still as discreet as before: "Calion, the 81st."

The name echoed in Aragorn's mind, but he gave nothing away. The silence stretched between them, the air thick with unasked questions. "Aragorn, son of Arathorn," he responded with a slight nod. "Why do you help me, Calion?"

Calion remained still, his eyes assessing Aragorn as if weighing the weight of each word to come. After a long pause, he answered in a voice barely louder than a breath: "It is best not to be alone... in these places." A pause, as if he carefully considered each word before speaking. "For now, I watch. The rest will come... in due time."

A silence settled once more, the forest noises reclaiming their place. An owl hooted in the distance, and the leaves trembled under a light breeze. Aragorn continued to observe the stranger, his mind alert, but part of him sensed that, for now, this man was not an enemy. Calion turned back, gesturing the way forward with a hand, and Aragorn, still wary, chose to follow him.

They moved forward together, their steps merging with the rustle of fallen leaves. The aura of mystery surrounding Calion only grew, but something about his walk, his silent presence, suggested that, despite the shadows around them, they walked, for the moment, on the same side.
