Why am I alone?

Girl x Girl mentions in here. If you don't like it then go elsewhere. (Only rated mature because of language and deeper topics) there is no smut or NSFW content in here because I'm not comfortable with it.

Home world has suffered and grieved over 6000 years after Pink Diamonds shattering, but with the hushed reports and news that don't make sense, that already leaves every gem and even the Diamonds confused about the accident. There is a new topic that approaches. On accident a few gems sent to polish Pink's room to keep it clean in her memory and out of command of Blue Diamond find a hidden entrance leading to a chamber. The chamber itself doesn't upset the curious Turquoise's but whatever was inside it has them call upon White Diamond herself.
Even though no one has had the chance to even be in white diamonds presence since the accident, White actually arrives at Pink's chamber in front of the terrified gems that called upon her.
When White sees what's inside the hidden room, she orders everything in the chamber to be destroyed and to never be spoken of again or they would be shattered, but when it comes down to the last thing that unnerved the gems the most instead of destroying it, they unintentionally activate a war machine with the power to withstand any Diamonds abilities and can even harvest it and use it for itself. Now sent on a mission to earth with the weapon on board, memories resurface, when lies and forgotten truths are revealed, will it help The Crystal Gems save the Earth again? Or is this weapon the cause of their doom and earths destruction?
