Darkness Once Upon A Time

Once upon a time
In a land so far away
Darkness will surround you
And from this you shall not stray

Understand your values
Purity is a must
Keep in mind your morals
In darkness you will trust

This is no illusion
This, not even a dream
Darkness has consumed you
Please try not to scream

This goes beyond theory
Philosophy unexplained
Come up with a form of reason
Before darkness has you chained
