This next file also deals with the future and possibly an alternate reality as well, since the T.D.D. doesn't state exactly what we are dealing with. Presumably the alien inhabitant(s) knew, but they left no records or clues to help us out in deciphering the disks at hand.

Mysta
of the MOON

    Attention, all wavebands! We now transvize to Terra City, to the annual contest awards of the Youth For Science convention...The winners of the first honors in the Mysta Fellowship tests will be introduced by the chairman...

    "This award, a year of instruction in the laboratories of Mysta of the Moon...Advanced research under the personal direction of the Queen of Science...And the winner...Bron of Earth sphere six! Now if the circuit is clear, Mysta herself will confirm the appointment, my boy!" says the Chairman of Science. On a huge wall monitor appears the lovely image of Mysta of the Moon from her moonbase.
    "Congratulations, Bron, your thesis on astrophysics impressed me greatly..." But as Mysta speaks on, men of evil also listen...
    "But I don't get it, Face! This contest stuff, where do I fit in?" asks a Bron lookalike.
    The Face replies, "Elementary, my pretty brain-boy! With your scientific training, you are the ideal replacement for this unlucky Bron!"
    "Replacement? Why I couldn't..." but he is cut short...
    "Shut up! I've been planning this for months. It's all arranged! In four lunar hours she will pick you up at Space Terminal Zeta...as for your credentials...here they come now!" cackles the Face.
    "A zap from the dark as he left the convention and...Presto! You are Bron! Dispose of him, men!" orders the Face.
    "No, Face...don't feed him to your tanks! I can't...I won't..." Again the Face cuts him off.
    "You won't? You would rather return to Kafka's colony? Your flesh rotting...bones like straw...your mind in torment night and day?" taunts the Face.

    Later at station Zeta...

    "Circus spacers clogging all the entry ramps, robot!" Mysta says with impatience.
    "Wait! There's our in-flash! Controls to neutral and ride their tractor-ray!" Mysta commands her robot companion. As Mysta and her faithful robot exit their ship...
    "And now for our prize winning student...stay here...I'll find him," commands Mysta.
    "So much viso haze...his features blurred...perhaps I'd better page his name" thinks Mysta.
    "There she is...Mysta! She's looking at me...she must suspect!" worries the Bron impostor.
    Suddenly a scream rings out..."Look out! That cage..." and a huge cage breaks loose from its chains in midair.
    "Cables slipped...ape cage crashing! And the Pluto buzzardons!" cries out a worker as the cage slams to the ground and the deadly beasts are set free!
    "To me, robot! Ultra-speed!" Mysta quickly commands.
    "That man...the apes got him! And I can't risk a full ray shot! But now I can!" Mysta thinks as she ray-guns the first ape.
    "Eat this lightning, killer! And the other one...the staircase... after him, robot!" orders Mysta!
    "Swamp plague on those buzzardon's talons! And six to kill! That's one!" Mysta ray-guns down the deadly alien bird.
    "Four down--five down...and now the last one!" Mysta gleefully chants. Bestial snarls of rage erupt as primitive fury and man-made force clash in battle.
    "The heat ray, robot!" Mysta again commands her robot. And it is flaming death for the loser's lot! Soon...
    "These papers! It is Bron our student!" cries out Mysta as she holds the impostor in her arms.
    "That first ape clawed...Quickly, robot! To our cruiser with him!" Mysta and her robot hurry to their space ship with the injured fake Bron.
    "Check his blood-tag, administer plasma in 12 gram flow...we must get him to the lab...the heart pump!" Mysta states.
    "Three hours...The ape-virus at crisis-plus in him. But there is still hope...land on beam!" orders Mysta.

    In the lab...

    "The virus count lowers! We've done it! He is saved! Come, let him sleep!" And, with that, Mysta and her faithful robot companion leave the impostor Bron to sleep off the deadly effects of his ordeal, his life saved, yes, but for what evil end?
