A Word of Warning

I can destroy cities,
Though I can't hold a candle to some,
But I can do more damage than most,
And I'm ready for you to know the truth.

A word of warning,
You might never know,
The worth of your words,
The strength behind them,
to bring on destruction,
You're own is in the works.

My very essence has brought forth,
The reign of kings and queens,
It has also brought the destruction of worlds,
Kingdoms and nations,
Until the world comes to an end,
I will be on a path to exalt and destroy,
Anything, Everything,
All you hold dear.

You will use me,
Because you always have,
Cheaters and Preachers,
You're not exception,
And I will never grow tired of it,
I am eternal, I am immortal,
I am eternal, I am immortal.
