Sentinels vs Dragons 3

These dragons, I think, are more than they seem
How else could they stay in the fray with machines?
and how come I never find a body on the ground?
I don't travel too far, but I took a look around
all I found was scrapped machines and debris
no bones or scales to be found, anywhere that I could see.
And I swear I've seen them glitch, it's not imagination
I think they are projections of some kind of simulation.
Maybe it's martial training for the metal battle mind?
Or maybe it's entertainment where they play to kill time?
Either way, I don't see it ending any time soon.
So it's time to fly away, go chill out on a moon.
