Espers are magical beings which once lived peacefully with humans. However, humans soon began to get jealous of the Espres' emmence power, and began to try and drain it from them, to use as they desired. In the hands of mankind, magic was a horrible destructive force, and thus a war ensued. In this war, the War of the Magi, civilization was almost wiped out completely, So the Espers created a new world, deciding that it was best the two species lived apart, and left the humans to lick their wounds. However, in later centuries humans discovered the Gate to the Esper World. One such human was a girl named Madonna, who fell in love with an Esper and together they had a child named Terra. Another was emperor Gastahl, who brought armies into the Esper World, so he could take them prisoner and use them to harness the power of magic. The Gate was sealed, but sealing it could only be done once, and those who had been taken were lost. Some Espers, like the Esper Ramuh, escaped Gastahl. Others were not so lucky, and died. Thankfully there was something very important about Espers which Gastahl did not know. That was that an Esper's power can only be controlled by a human once the Esper had been reduced to Magicite, Magicite being what remains of an Esper after it dies.
