Alright, this is my first published story. As it goes, humans are gone from Pandora and are presumably extinct. The Planet is healing nicely but the experience has affected the people. Peace reigns again and the Na'vi can live their lives as before. Of course until a new race of aliens descend from the stars that is. -Avatar is the property of J.C and his people; everything else is of my own design and ownership.
Bathed in reflected light from the great gas giant Polyphemus, Pandora's nighttime hemisphere was glowing with bioluminescent life and from high orbit, the moon's surface was a bas-relief against the blackness of space.
And from that dark void glided a great ship, of a like never seen by the moon or its inhabitants. The long craft was dark, bar the quartet of engine mounts, which pulsed brightly and trailed streaks of slowly dissipating plasma. Hovering in orbit over the moon, the ship seemed to quietly regard the beauty of the world below. But at that moment, Pandora rotated the final amount to transition into daytime, the light from the three suns rapidly bringing dawn and continuing into full morning. Lights snapped on along the hull of the visitor ship and from the bottom of the craft armor plating shifted, leaving a gap on the ship's belly; from the gap there was a flash like lightning and gases billowed as a tiny ellipse shaped object blasted from the gap and fell towards the moon, increasing speed as it was pulled in by gravity. As its payload entered the atmosphere and vanished from sight, the ship seemed to hesitate, waiting.
Far below, on the surface the transition from awake to asleep and vice versa was taking place. Nocturnal predators retired to their nests and burrows and all across the daytime hemisphere, the daylight side of Pandora began its daily rhythm. In a secluded part of a continent-wide jungle, a Viperwolf was settled in a bush napping; a moment later the ground four meters away exploded as a meter wide object slammed into the ground, spraying dirt and small stones in every direction. Birds fled to the air and woken from its sleep, the Viperwolf gave a frightened yelp and ran into the safety of the deep jungle. At the bottom of the eight meter impact crater sat nestled in a bed of smoldering ashes and blackened glass, a four foot long oval shaped object. It was bloody red and metallic, with gray streaks of ceramic like substance running across it in odd symmetrical patterns. The object glowed with incredible heat from its descent, and as it cooled, it split along its lateral equator, exposing a mass of maroon flesh. Slowly and tentatively a cone shaped fleshy head extended itself from the shell, a triple set of marble like eyes studying its surroundings, stubby snout taking in the jungle air, and a pair of long tentacles, broad and flat at the ends and tipped with a fan of writhing flexible spines, uncurled from the body and waved in the alien air, testing it. With a bizarre warbling sound, the hatchling alien creature shoved its oar like tentacles into the rich soil and began to burrow beneath the surface.
Then far above the Moon, as silently as it had come, the ship turned tail and headed back into the darkness. Its pilots not taking a second glance back. For the time being, their purpose here was finished.
