What is your Duty
To serve Emperor's Will.

What is Emperor's Will?
That we fight and die.

What is Death?
It is our duty.

And what is your Duty?
To serve Emperor's Will...

"Space Marine's pledge"

And what are the achievements
of your fragile Imperium? It is a corpse
rotting slowly from within
while maggots writhe in its belly.
It was built with the toil of heroes and giants,
and now it is inhabited by frightened weaklings
to whom the glories of those times are half-forgotten legends.

I have forgotten nothing and my wisdom has expanded far beyond ,mere mortal frailties.
