Part one, It is very short, as there is no way I could ever make this fair.

The crescent shaped vessel departed the rift. Its long 'tail' section powering it forwards like a two pronged dagger. In the dark sepulchre mounted on the dorsal surface f the ship, the deceiver relaxed. His avatar was secure. Soon the C'tan would claim a new universe as their own dominion, and they would again rule the stars.
"Captains log, star date 4753.23; The Enterprise is currently entering the Baris System. We have recently lost contact with the colony there, and have been sent by Starfleet command to investigate."
"Captain, we are now entering sensor range," said Data. "Scanning for life signs" the android turned in his chair, "Captain, there are no life signs on the planet," Stunned Picard turned pale.
"Commander are you sure?" The commander turned back to the console and keyed in a new sequence. "Yes captain, there appear to be no life signs on the planet including single celled life forms."
"Prepare an away team," muttered the stunned Picard in horror.
Meanwhile, in orbit of the system's star the crescent vessel began the slow process of incarnation. A snaking tendril of energy curled from the star onto the vessel. In a chamber, deep within the ship A block of metal glowed. The dark slab began to uncurl at the edges, forming into a shape.
On the planet, commander Riker and several security ensigns materialised. For once the captain was following procedure and only sending one ranking officer on the mission. On the far side of the room stood a strange hunched-over metal skeleton. Commander Riker walked up to the spectral figure. "Ensign Reall, what do you make of the "He was cut off in mid speech as the skeleton turned its head towards him. It's leering grin and glowing yellow eyes stopped a hairs breadth from his face. It's cold arm shot out and picked him up. As Reall fired his phaser the machine pirouetted and hurled Commander Riker at the man like a limp rag doll. The man's neck snapped backwards to an unnatural degree killing him instantly. They fell, two more security officers ran into the room weapons drawn. They shot the creature. It strode towards them with a strange swaying gait. As they tried to change their poorly designed weapons settings onto the kill mode the creature reached them. It lifted one high into the air, and used him as a club to kill the other. Then it snapped the unfortunate human's neck.
On the alien ship The Deceiver smiled inwardly, watching the carnage through the eyes of the warrior. Behind him a brilliant flash of light erupted into the darkness. "Shouldn't you know better? I mean I don't like Riker very much but this..." Q said loudly in English. The Deceiver turned to look at the interloper. Its presence was strange. The Deceiver stretched out the arm of his avatar and shot a bolt of cobalt lightning at the invader. Q disappeared and manifested himself behind the metallic creature. ";Now really, this is NOT how you treat a guest" The deceiver turned, realising what the creature was he slowed down time aboard the ship, and reached into the head of the visage, which reacted at normal speed. The metal claw passed through Q's head. The Deceiver felt the forces that made up the being before him, and pulled. Too slow Q felt himself slip from consciousness, into raw energy, and felt the hungering being of the Star Vampire consume him.
