History
Over 5,000 years ago, the Homeworld Gems arrived on earth using the Gem Colony Ships and soon after, created the warp pads for faster and easier travelling. During the time they had on Earth, they had built the Kindergarten in order to create more Gems at the cost of destroying the Earth's of its resources which would inevitably cause great harm to the planet and its inhabitants.

Feeling compassion and seeing the error in their ways, Rose Quartz rebelled and formed the Crystal Gems and had started the war for earth known as The Rebellion. Both sides fought valiantly against each other but on the battle that took place in the Gem Battlefield, the Crystal Gems finally won the war which drove the remaining homeworld gems to retreat back to Homeworld.

The first member of the homeworld gems to be seen many years after the war was Lapis Lazuli, who had been trapped for an unknown number of years inside a mirror before Steven freed her. He healed her and she went back to the homeworld, only to regret it soon after as homeworld had advanced so much in the time that she was trapped in the mirror and had found herself out of place.

The second member of the homeworld gems to be seen was Peridot, who checked on the current status of the Kindergarten before leaving after finding a Crying Breakfast Friends! sticker, which made her think the site was compromised.

She returned in "Marble Madness", where she tried to check on the Kindergarten again before Steven distracted her, which prompted her to kill him. However, the remaining Crystal Gems intervened and destroyed the power source of Facet Five, which made Peridot tell them that she would report what had happened.

Lapis was seen again in '' The Message", this time using a wailing stone in homeworld to relay a message to Steven and the Crystal Gems of an approaching threat coming to earth. Unbeknownst to them that Lapis had become the informant of the threat.

During the events of "The Return", Peridot brought with her two homeworld gems, her escort, Jasper and her informant, Lapis Lazuli, who was hesitant to aid them. Jasper helped Peridot defeat the Crystal Gems and take them back to the homeworld. However, their plans were foiled when the Crystal Gems managed to fight back and defeat them, crashing their Gem Warship in the process and stranding Peridot somewhere on earth after she escaped on an escape pod. In one last ditch effort to defeat them, Jasper fused with Lapis to become Malachite, a monstrous fusion who sealed herself in the ocean by Lapis' will.

Peridot's primary mission on coming to earth was seen on "Keeping it Together". She had, on various occasions throughout her appearances, stated on checking up on something called the cluster. In the aforementioned episode, The Cluster is revealed to be the result of an experiment done by the homeworld gems on fusion. The homeworld gems had taken the shards of fallen Crystal Gems during the war and experimenting on them, forcibly fusing them to create it.
