So is it about metaphorically hunting down the demons who are tormenting/punishing you for the crimes you have committed? Because otherwise it doesn't make much sense, it is the Furies/Erinyes who have no truce with you, not the other way around.
Uh, I´m not sure about your crimes - I guess you´ll have to wait, play the game, and see. It is safe to assume that you do battle with your inner demons. You know how life is when you´re no longer a teenager... DEMONS EVERYWHERE!
Well, I was of course just hoping to extract a bit more info...
Being familiar with the concept with the Erinyes means knowing that they cannot be fought, opposed, reasoned with, or escaped. There's a partial exception to the third one in Aeschilus' Oresteia, and even then, it takes place after Apollo himself admitting to Orestes in the Choephoroe that he cannot do anything to protect him from the Erinyes, and it involves Athena together with Peitho (the goddess of persuasion) persuading the Erinyes, at the very end of the Eumenides, to accept the acquittal of Orestes by promising them basically to become part of every aspect of Athenian society (that is, carrying out the transition from blood-law, which the Erinyes symbolize, to tribunal justice represented to the Areopagos tribunal instituted by Athena in order to judge Orestes).
So if you say "if you acquainted with the concept of the Erinyes you should get it", no, sorry, doesn't work. It means "no truce with something you can't fight" which, apart from quoting the title of a semi-obscure poetry book by a Welsh nationalist, doesn't make a whole lot of sense.
