Gigantic Aeterna trunks rose like colossi toward the sky, their fronds intertwining in a canopy of vegetation that filtered the light in a thousand shades of green and emerald. In the solemn silence of the forest, broken only by the hum of respirators and the crackling of leaves under their boots, Kai and Caspian advanced side by side.

The organization's distinctive symbol stood out in white on the shoulders and chest of their dark suits, clearly etched above the reinforced fabric to identify the Earth expedition. Their masks reflected the gleams of the pristine nature around them. In the clearings, elegant creatures with iridescent cloaks moved gracefully, craning their necks to graze on the lower foliage. Their lungs regularly expelled thin clouds of vapor, perfectly adapted to the alien atmosphere that would have been unbreathable for humans. Caspian kept his eyes on the animals' movements. With calm, precise gestures, he occasionally raised the scanner to record every detail, memorizing trajectories, bone structures, and breathing rates without missing a thing. His concentration was total, impassive in the face of the wild allure of the place

Every muscle was ready to respond at the slightest sign of danger, his eyes intently scanning the shadows of the highest branches and the density of the vegetation.

The perfect understanding developed over years of friendship made any words superfluous: a glance of understanding behind the dark visors was enough to understand each other, while the infinite forest of Aeterna continued to reveal its secrets with every new step
