Nintendo was threatening to sue Stefan for copyright. Stefan changed the name to Graal. Graal the Adventures original story was about four colored Graal's that when all four were obtained by someone it would open a golden gate to a golden city. The golden gate is on iClassic next to Galen. However entering it will just have you pushed back. That's pretty much it. The game now really has nothing to do with the actual four Graal's.
If you want to know more ask Dusty or maybe he'll pop up on this thread.
