Gregeras, Who Taught the Flame: "Sylvas of the Cleansing Flame is a legend among their people. Their heroism during the great wars entered myth and every young Innerterrestrial listened to tales of their exploits at least once. Not many know of Sylvas' teacher though. When they were but a spawnling, Sylvas was already powerful. But power alone isn't enough to attain true mastery of the Subtle Art, much like an uncut diamond cannot by itself become a jewel."
