Writing on a Wall

Come away, young man, where the ground is red and you need a mask to breathe
Oh, it's been so hard but your luck could change if you'd just roll up your sleeves
We had tried our best to warn before but it didn't get you far
Now we're here again with a wish to mend your agonizing scar
Open eyes, young man, vigilante hands and a heart prepared for pain
You will lose much more in this vicious war, past and present stay the same
But the time to come will be altered some if you listen to our song
Do we sing in vain? Does the fact remain there is nothing can be done?
