The Beast of Darkness: Don't think you can tie me with that yoke.
The Beast of Darkness: At the moment you got that husk, I was already unleashed.

The Beast of Darkness: Your new companions
The Beast of Darkness: The ones who you should protect.
The Beast of Darkness: A warm light.
The Beast of Darkness: Maybe it isn't bad that you depend on such a thin chain for now.

Translator's note: When the Beast of Darkness speaks to Guts, the words "I" and "you" are one and the same. It shows that it recognizes itself as Guts. I've only indicated it in one line for clarity's sake, but it's the same for all of them.
The Beast of Darkness: But since they are with you, the more they are related to me, the more these idiots get to expose themselves to the jaws of death.
The Beast of Darkness: And they will be crushed, torn and ripped apart soon
The Beast of Darkness: ...Just like that time (the Occultation)
The Beast of Darkness: Cherish them
The Beast of Darkness: Only to lose more

The Beast of Darkness: For now it's OK, I'll follow you
The Beast of Darkness: I'll gather my breath at the bottom of my deep darkness
The Beast of Darkness: I'll save my power as much as I'm tied and suppressed
The Beast of Darkness: And then... in the end...
Basically it predicts that Guts' friends will die, not unlike what happened during the Occultation, and that then it'll come forward and completely overcome Guts. One thing I noticed people don't seem to be doing is to question whether that will actually happen or not. Are Guts' companions really going to die? Personally I hope not. And I don't think their deaths would help Guts in a fight against Griffith, quite the contrary actually. In short, what I'm saying is that we should take what the Beast of Darkness says with a grain of salt.
