Based from a Strong Force Power only known to be wielded by one Very Strong Sith. The green flame could be used to consume everything on a vast VAST scale. The wielder only being able to survive by using a field of sorts. To show off your great power and your ability to wield this strong destructive force just type "flame" and the center ball will circle around as the green flames flicker around it. ENJOY THE GREAT POWER IN YOUR OWN HAND (This is only my interpretation of what it might have looked like if someone was to play with such a power.)
