At the first flash of red on the bank of meters Apprentice Burnerman O'Rielly had slammed the safety helmet on his head; he was already throwing open the lock to the burner room. Power of the universe trapped here and ready to destroy its captors given one chance! Swiftly O'Rielly unlocked the controls and reset them. "Fusion control two points low, sir."
