Why is the song titled "king of terrors" instead of "king of terror"?

typo?

It would mean that that particular king terrifies people in more than one way...

Also, it is a Edgar Allen Poe quote from The Pit and the Pendelum...

"The inquisitorial vengeance had been hurried by my two-fold escape, and there was to be no more dallying with the King of Terrors."

That part is also featured in the song itself, you can hear Allen "growl-speak" it in the middle part.
