The Grand Dragon Balls

The Grand Dragon Balls
The Grand Dragon Balls are similar to Earth's in almost every way but each ball contains a powerful Dragon. Each ball chooses who is worthy to protect them and, based on that dragon's personality, will aid their guardian in battle. Each dragon is capable of granting one small wish every five years. When all seven are brought together they fuse into one Grand Dragon. This has yet to happen. Their origins are currently unknown and can be found anywhere on the planet.
