I just saw a Shadow Mordor E3 [trailer](https://www.youtube.com/watch?v=X8hoTfZ3vUc) and in one of the orc's lines, he says:

> 
> He moves like a ghost; fights like a [the] devil!
> 
> 
> 

**Is this accurate to what words orcs use or what they believe in (or merely a device the game designers/writers used of their own volition)?** If this *is* accurate, what *devil(s)* could he be referring to? E.g. could he be referring to Sauron as in *"He fights like Sauron!"*?
