This is just my imagination talking but I think that the Gems was first sent to Earth to conquer the planet. GAP, Rose, and other Gems lead a rebellion agianst the Gem forces due to all the pain they caused throughout the universe to stop. This caused the Gem Wars that eventually made the Conquering Gem forces to retreat from Earth. The remaining Rebel Gems destroyed the Galaxy warp to prevent further conflict. As time went by the Gems fear & paranoia that the Evil Gem Forces will return grew. The ever growing paranoia caused some unknown curruption to happen to them that eventually turn the remaining rebel Gems (exept GAP and Rose) into monsters.
