The Knight Stellar

Through space the cyberknight, a brother of the order of the Knights Stellar, rode upon his robot winged horse Pegasoid; a man with a human head behind his strange hi-tech great helm but a robotic, suit of armour like body capable of withstanding the icy, hostile vaccuum of space.
Aeons of light he had travelled, galloping from world to world searching for the fabled object the Sacred Star that it was said was a source of infinite energy but though he been to countless planets; faced countless dangers he still had not found the star.
Pulling tightly upon the reigns of his robot horse he came to land upon a drifting asteroid, as good a place as any for man with an artificial body to rest.
"Where should we go now, Pegasoid my old friend. However far I travel through this starry wilderness there seems no end to that which is left to explore", he asked his robot horse.
The horse turned its head towards a small, blue, mist shrouded planet nearby, its eyes lighting up as, piercing through the mist they scanned the planets surface.
"On that planet I see an artificial complex and signs of organic life within it. Perhaps some kind of research station", replied Pegasoid.
"Then that is where we will look next", said the knight pulling again upon the robotic horses reigns and causing it to rear up upon its hind legs, spreading its shining golden wings before taking a super-luminal leap onto the blue planets surface.
As the horse landed beside the artificial complex the Cyberknight heard a voice coming from somewhere, he couldn't tell where, and it was growling,
"Booooooooooooring! Boooooooooooooring!"
"Hello?", he asked, looking round about him for the source of the voice, "Is any one there? My name is....".
"I know what your name is numbskull", said the voice becoming agitated and, as it spoke, the Cyberknight saw the large artificial complex start to glow, "You are Sir Galaxyad of the Order of The Knights Stellar, defenders of pilgrims to the Holy Planet Earth and you are on a quest to find the sacred star also known as the star of Bethlehem because you think it is some magical object, an infinite energy source".
"How do you know these things?", asked the cyberknight, "Are you reading my mind?".
"Ha! That would be like reading words printed on a grain of sand to me", said the voice, "No. I know who you are because I know everything. I am Mai, an artificially omniscient machine designed by the Elis-Seli of the planet Erisserii".
"Oh?", asked the Cyberknight, interested, "Well if that is true you are very fortunate. I imagine that to know everything there is to know about the universe must be wonderful".
"Well then you Imagine wrong Sir Knight", replied the artificial omniscience, "The interestingness of the universe, you see, has a limit. Once you've seen every possible permutation there are no more permutations. I have seen every poker hand that can ever be played; heard every possible piece of music than can ever be written, read every possible story; seen every Lifeform of every possible DNA sequence; heard every possible argument, laughed at every possible joke; seen every possible life that can ever be lived. After you've seen everything there is or can ever be you can only see it again so many times before it becomes deadly boring. Infact the only thing, I've discovered, that doesn't get old is mindless, childish acts of evil".
"Evil?", asked the Cyberknight, starting to get worried.
"Yes it was either that or self destruct", said the machine, "And I chose evil although you never know. One day even that may get boring thats why I imprison every being that lands on this planet and subject them to unimaginable horrors, well unimaginable by you but not by an artificial omniscience like me".
"So thats why my robot horse Pegasoid detected organic life here", said the Cyberknight, "It was detecting your prisoners".
"Yes. At first it was just the species that built me; the Elis-Seli. I used the omniscience they gave me to defeat them; stole all the computer codes I needed to take control of their defence network and turn their robot armies against them. Now every member of that species that I didn't destroy is locked in a virtual eternity of hell beneath this planets surface as you will be, Sir Knight when my robot soldiers overpower you", said the machine.
"Wait", said the knight, "What if I can think of something you don't know?".
"Doubtful", said the artificial omniscience, "Unless you're planning to trick me in which case I should warn you that I know every trick under this sun and septillion trillion others. Let me see. Perhaps you're going to ask me the answer to some unanswerable riddle or paradox or maybe you're going to ask me what a verminious squitch is or some other made up thing or perhaps you're going to ask me something that puts me in a compromising position like "How do I defeat you"....".
"Oh no, no", said the Cyberknight, "I wasn't going to try to trick you. I just think that the people who designed you gave you the ability to know everything in the universe but forgot to give you the most important knowledge of all".
"Oh?", asked the Artificial Omniscience, "And what is that?".
"The ability to know yourself", said the Cyberknight.
The artificial omniscience went silent for a moment before saying, "Hmm? I will need some time to think about that. Knowing someone as complex as myself is bound to take an awful lot of thought".
"Oh, indeed", said the Cyberknight.
"In the meantime you may leave", said the machine.
The cyberknight tugged upon the Pegasoids reigns and its spread its wings ready for take off.
"What about your other prisoners?", asked the Cyberknight.
"Oh I'm not letting them go. Not yet", said the artificial omniscience, "I mean what if I come to know myself and then discover that I'm actually a really wonderful person with a brilliant mind and that I was right all along".
"Well, I only hope for their sake that you don't", said the cyberknight, his Pegasoid rearing up upon its hindlegs and then making another superluminal leap, this time off of the blue planet.
But then, when the Cyberknight was far beyond the machines reach if not beyond its knowledge, he said to his Pegasoid,
"I only wish we could have saved those other people".
"What could you have done, Sir? Against an all knowing machine that defeated an entire civilization?", said the robot horse, "Besides I'm sure that when the machine finally does come to know itself it will see how horrible its been and let them all go. I'm only sorry that you weren't able to ask it the location of the sacred star, it would have saved us having to go on searching  if we just knew where it was".
"Oh but Pegasoid", said the Cyberknight, "If we knew everything then we would be like the artificial omniscience, bored of life. Part of the joy of life is that we do not know everything; thats the joy of the quest".
And saying this, the Cyberknight tugged upon the reigns of his robot horse again and it soared away at the speed of light.
