History
Spoiler alert: This article contains spoilers.

Pre-Krad Saga
The XGem was sought after by the Jewelians, who had taken the body of the deceased Hea, lord of Planet Deoh-Tah by Ruby. Ruby, under the guise of Hea, had ordered an attack on the planet Gan-Mah. In the war, over 90% of Gan-Mah's population died. The Elite Soldier known as Richer (who was a Master of the XGem) had used the power of the XGem to eliminate the remaining Morphs (that were known), and take the XGem to planet Earth, specifically Palmares Hill. Afterwards, Richer encased the XGem in a Crystal Grave, which also took Richer's life. On Earth, many rumors about a dragon coming to Palmares Hill were birthed.

Krad Saga
50 years later, Dr. Scar was sent to Gan-Mah to build a ship to retrieve the XGem, gathering many powerful dragons onto the ship. He convinced the lord Krad del Black to go to Earth to retrieve the XGem to revive his late wife, Topaz. By doing so, he used government money to build it, ignoring the cares of the people. He pretended the reason for the ship was to exile dangerous criminals, when they were really supposed to collect the XGem. When they reached Palmares Hill, Lance ordered them to find it, and promises full freedom for whoever finds it. However, they were all disintegrated by a force field caused by Illusion. So the Elite Soldiers aborted the mission. When Rocky and his friends went to the hill, Rocky was the only one who could get through the force field. He was told where to go by Illusion who had trained him to use his powers better. He then obtained the XGem after Ilussion put an image in his head. After obtaining the XGem and learning that he was chosen by the XGem, and that he looks exactly like Richer, he used the XGem's power to become more powerful. His appearance and attitude changed. He defeated Krad del Black with the XGem, and encased Krad's ship in crystal with a Crystal Grave to keep the ship from exploding and destroying the Earth.
