In 1527, during the Spanish Conquest of the New World, an object was found in Honduras near the ruins of a Mayan city. Until that day the object was thought to have been merely a myth - the LEGEND OF THE CRYSTAL SKULL - a skull made of smoothed quartz that had the power to reveal the future.
At the news of its discovery, King Charles V ordered the priceless treasure transported back to Spain immediately. But soon after the ship set sail carrying its precious cargo, the ship was attacked and plundered by the fleet of the famous pirate William Bellamy. Captain Bellamy amassed immense fortunes thanks to the power of the Skull and then, just before dying in 1553, he hid his greatest treasure on a remote island somewhere in the Indian Ocean.

In the years that followed, occasional references to the Skull were reported. But in 1677, the apparent last traces of the Skull were lost when a boat supposedly transporting it disappeared off the Yucatan coast.
Then in 1939, a French expedition found a document in Akumal that revealed the location of the Crystal Skull. The centuries had not diminished interest in the Skull and various nations used their best fleets to find what they hoped would be the ultimate weapon in the coming World War.

Now in the year 2323, space exploration has pushed far beyond the solar system. For centuries the whereabouts of the Skull has been lost again. The colony of Kiesh, not aligned with the confederation of planets, thirsts for more power. Through its Secret Service, the confederation has discovered that the captain of a Kiesh-bound expedition, Mr. X, has come into possession of a very old object: the Crystal Skull. 
Research has determined the Skull's power and danger. The confederation has promised an enormous bounty to anyone capable of stealing the Skull away from the colony of Kiesh. 
Because of this edict, a Skull hunter war has erupted throughout the system...
