"Ha. Like that would've worked. It's made of stone!" Obsidian said to the Gem who'd kicked the door.

Meanwhile, Moonstone was searching hard. Just when she was about to give up, she looked under the mattress. There, she found a red book with a giant yellow star on the front. The book was undamaged.

[i]What the...[/i] she thought. She opened up the book

On the first page was chicken scratch writing that look liked a child's. 
[i][u]Today I moved in with the Crystal Gems! They’re so cool, and I can’t wait to protect the Earth like them![/u][/i]

She flipped through the pages, the chicken scratch becoming more and more clear. She stopped on a page with pictures.

[i][u]Dad gave me a camera today! I found pictures of him and Mom on it after taking a selfie with the Crystal Gems. The first one is when Dad was younger. The second one is before Mom gave her form up for me. The third is my selfie! Oh, and after that I found a picture of Mom and Pearl. I wonder who took the picture?

[i]Woha....His mom is really pretty. Were these the people who lived here?[/i] She noticed that all of the people in the pictures had gems except for the man. 

She flipped further through the pages, reading them. [i]So, we're Gems? And we're from a place called Homeworld?[/i] She kept reading, gathering more and more information. Until she read the last page.

[center][i][u]Whoever finds this, hello. My name is Steven Universe. I’m a Crystal Gem, like Pearl and Garnet and Amethyst. Is that giant statue being to erode, the Temple? That’s where they live, er, lived. I don’t know who you are, but if you’re a Gem please. Please protect this planet for the sake of the people who live here. Homeworld will try to use it but don’t let them. Please. This is my final wish. Use all the information from this diary to help you. Learn from what I learned. Please.
-Steven Universe

"You guys, you need to read this," Moonstone urgently said, coming down the stairs. She placed the diary open to the last page on the kitchen counter.

Obsidian came over, reading the last page.
