The idea is simply the next stage of berserk for WAR, one which would tie in with the title Berserk and expand on its abilities. The backstory i have come up with is over time Broken Mountain has regained his powers and has obtained what appears to be an enraged form, a form capable of unleashing ones pain and suffering into the form of an attack. It is perfect for Broken Mountain to be the one to introduce this attack as he doesn't really utilize an axe but rather a grimoire. its an awesome way to introduce it as opposed to Curious George or Dorgono, who both gave us a cool intro to new attacks.
