LOTUS OF LIFE
Alisa: Please excuse me, Master. I finally found you, Master Karma- the legendary soul keeper.
Karma: I’ve foreseen this moment to come. The lotus of life had come to fruition. This is when my duty as soul keeper begins. I know why you are here, Alisa. You wish to revive your people. The one who perished in the battle with Demica a century ago. Demica is the creature of dark magic, one of the guards of the 7 ancient artifacts. The beast holds an unimaginable power that my efforts alone can not help. The myth is, you will need to find the knights of the light to fight the darkness.
