6655321 is from an extremely advanced race from an extremely distant galaxy. Everything that its ship can do stems from the ability to project gravity wells of varying magnitudes. These can be anything from gentle tugs to the strength of a black hole, and are used as propulsion to pull the ship around, as weapons and as defences.
6655321's race are essentially sphereical blobs, around half a meter in diameter that live in liquid Oxygen. They are spawned in identical groups of about 5,000, and only the most perfect are pulled out every few millenia to fill up the species, because once they mature, they live for a few hundred million years, so each generation only consists of around five thousand creatures. 6655321 is this generations 6,655,321 spawnling. He meets the standards to be released and given a task. If he returns, he will be deemed worthy, and allowed to mature, and become a full creature.
Their ships are spherical, and filled with liquid Oxygen, either at high pressure or extremely low temperature, depending on the pilots preferance. The ship acts as a life support device, because the creatures are so fragile. It is only three meters in diameter. Suspended in the center is a gravity isolation pod that the creature floats in when the ship is projecting black hole scale gravity wells for high speed movement.
They have no real concept of wrong, their society lacks a concept of murder or death, because a body can easily be replaced by another, identical, if slightly less perfect twin from your spawn bed, and meticulous records are kept, so no knowledge is ever wasted.
6655321 has been sent to destroy a ship/creature that witheld data from the whole, and recover the data pod inside. he spent several thousand years geting here from his galaxy, but that sort of time is like a week to him
