Not a watchman...

With all ears, vigilant in day and night. We are not called watchmen and don't know what those people call us.
We have weapons which we made ourselves, powerful and strong. Enemies cannot predict our tools and attack. We have our own strategy, no one can understand those techniques which are changing time to time. Our one warrior is enough to fight an entire battalion of humans. Always we are in defense mode, we wont attack anybody if they are on their way.
