He went insane and no one should explain replacement.
When his brain could not deal with the environment.
Why there main objective was the replace him.
Why there was never a directive for him.
All we know is that no one helped him.
In his insanity he grew dreary.
All the gravity made his muscles weary.
He mostly had no will to stand.
His non-notoriety mental capacity.
Left no one with a capability to help. (Not that any one tried)
All these memories of horrible things brought him to his knees.
Some philosophical stories he had never heard.
No mystical series of miracle proportion ever came.
He was now a vestigial, with distortion to the tale, of his insanity.
No one helped him now he is worthless, thanks people thanks surroundings.
