The actually dialogue for EXO's MAMA MV (Intro) :
I'm 98% sure this is correct.
"When the skies and the grounds were one, the legends, through their twelve forces, nurtured the tree of life. An eye of red force created the evil, which coveted the heart of tree of life and the heart slowly grew dry. With tend and engrace for heart of tree of life, the legends hereby divide the tree in half and hide each side. Hence, time is over-turned and space turns a skew.The 12 forces divide into 2 and create two suns that look alike into two worlds that seem alike. The legends travel apart. The legends shall now see the same sky but shall stand on different grounds, shall stand on the same ground, but shall see different skies. The day the grounds be kept a single file before one sky in two worlds that seem alike, the legends will greet each other. The day the red force is purified, and the twelve forces reunite into one perfect root, a new world shall open up"
