The mangastream translation is out and it makes me even more worried for Lucy.

Zeref's thoughts on rewriting the book of E.N.D.: "The simple act of doing so would errode their very being and they would be consumed by darkness'"

This isn't just Lucy being killed by the heat of the flames, which Gray can counteract by cooling her down, but something far worse that might not kill her body, but have some really bad repurcussions... if she can survive it at any rate.
