As the Diamonds slowly approach Homeworld's solar system, the new pair, in a small observation room, observed the many fascinating things in the near-infinite space on the other side of a large, rectangular window. Pink was like a child, staring at lone gas giants and asteroid belts.

Black: Do you enjoy the stars? You've been sitting by the window for hours.

Pink: Is that what those things are? They're so...so...

Black: Colorful?

Pink: Uh, yeah! They're so colorful, and there's so many!

Black: That's because a star is made up of various gases and other types of matter, they draw things in via gravity with in incredible pressure, and then it eventually becomes like those out there.

Pink: What else is out there?

Black: Hm...well we already established the stars and planets, but there's other things to find. Such as star systems, that's when a collection of planets orbit around one or more stars.

Pink: Orbit?

Black: That is the act in which a planet moves around the star over the course of several months.

Pink: What's a "month"?

Black: Usually a span of 30 or less planet rotations.

The large door on the other side of the room opened, and White Diamond stepped through.

White Diamond: Get ready, you two! We are approaching Homeworld!

Pink: We're finally there?!

Black: I am looking forward to seeing our home planet for the first time, as well as meeting our other two Diamonds.

White: Oh yes, I believe Yellow requested that she assist in your first colony as soon as we land.

Pink: Huh? Colony...?

Black: In order to produce more Gems and acquire more resources, we will find other planets rich in materials and take control of them.

Pink: So we all get to make a colony?

White: Yes, well...about that, Pink. We had only expected there to be one more Diamond, not two.

Pink: Well, what does that mean?

Black: It means you weren't expected, and we do not have the same purpose. I do not wish to sound, rude, but it simply means that you currently have no purpose.

Pink: O-Oh, I see...

The pink Diamond looked down at the floor in disappointment.

White: Fret not, little one! I already came up with a task for you as well, which is why you'll be with Blue.

Black: See? There's a positive in most negatives.

Pink: I don't even know what those mean...

White returned to the main chamber of the ship as something caught the eye of the shortest Diamond.

Black: Oh? Look, there it is, Pink. Homeworld...

The new world they saw was much more pleasant to look at than that previous chunk of rock they originated from in all aspects of the word. The planet's surface was mostly white, with some places gleaming like a gemstone, and had two rings.

Pink: Wow...it's, it's...

Black: Beautiful.

Pink: ...Yeah, it's that. Beautiful...

Black: We should get ready, the ship is about to land.

Pink: Right. ..Hey, Black? Do you think the other Gems will...like us?

Black: Explain.

Pink: I mean, from everything you're telling me, and the fact that I wasn't... I don't know if I can be-

Black: There is no reason to have doubt, the Gems are loyal to all Diamonds and nothing else. Despite not expecting you to exist, they will not think less of them even if there were a third new Diamond. There may even be a possibility where your existence leads Homeworld towards an even greater future than it currently has.

Pink: Black, do you really think so?

Black: Yes. Now let us go discover that future.

The Captial city of Homeworld was one of grand design. On every corner, every square, every courtyard stood statues depicting Gems of high regard, both soldier and non-soldier alike. Other sites were that of stont spires reaching thousands of meters into the sly, along with massive structures seemingly floating off the ground, held by some unknown force. In the very center of the city stood four large buildings on each corner of a larger building shaped like a diamond, each corner having the colors of the four known Diamonds.

The ship landed on the white structure, where a large group of many different Gems had gathered in front of, cheering for the reveal of their newest leader. The three Diamonds exited and looked down at the cheering crowd, Black being the least interested in such loud noise.

Yellow Gem: Black Diamond has finally arrived!

Red Gem: But look! There's another, standing next to White Diamond! She's pink!

Blue Gem: Now we have five Diamonds leading us, what a joyous occasion!!

At that moment, all the Gems below crossed their hands into a diamond shape whilst standing in rows, perfectly organized and uniform.

All Gems: Praise the Diamond Authority!!!

Black: See Pink, they are completely ecstatic...that means they are happy to see you.

Pink: Wow...there's so many. And to think, I-

???: My Diamonds...

A small Gem approached White and the others. It was the strangest one the two Diamonds had seen yet, as the thin, short haired Gem held both arms out, as if presenting something grand. Her skin was pale, and her "clothes" were a mix of both gray and black. And sitting in the middle of its forehead was a oval-shaped stone, something not like the others. But it was her expression that somewhat disturbed Pink, it was a simple smile, but something about it felt...unnatural. (Pic not smiling but I liked it.)

Pink: Who is that??

Black: That is...a Pearl. A subtype of Gem, servants to other Gems of high regard.

Pearl: Black Diamond is required by Yellow Diamond immediately.

Pink: Already? But we just got here!

Black: It's fine, I wish to begin work as soon as possible. You need to go see Blue anyway, I'm sure we'll both be busy today.

Pearl: Come with me, Black Diamond.

Pink: Oh, ok...I-I'll see you later then!

The shortest Diamond simply nodded and walked off with the Pearl, leaving Pink standing by White, unsure but optimistic.

(Some time later.)

Black: The design of the city is...efficient. However I believe a more advanced motive of transportation is needed, we could save more time if we could move ourselves and other things quickly around the planet.

Pearl: Yellow Diamond is planning the construction of a 'tram system', but is currently occupied with other military projects.

Black: I see, then I shall request that such operations will be my responsibility.

Pearl: We have arrived.

The building standing before Black was not like the plain stone, but was engraved with humanoid figures and decorated with non-powered gemstones. The Diamond entered the building alone, where after a short hallway he encountered the one who summoned him there, within a type of "Throne Room". Yellow, much like White, was much larger than Black or Pink, and her appearance was that of a powerful military figure. Alongside the Diamond stood another Pearl, this one with a similar hue of her superior.

Yellow: So, you're Black Diamond. A little smaller than I expected...

Black: My height is irrelevant, what matters is my purpose and my ability to fulfill it. It is to create more efficient and powerful technology to aid Homeworld to complete universal authority, to colonize every planet, every star system, to make the Diamond Authority the greatest empire in all of creation. That is my purpose.

Black spoke almost like a machine, saying everything on his mind without pause, then became silent, almost motionless, waiting for his first official act.

Yellow: You sound quite eager to get started, so we'll be quick about this, Pearl.

Pearl: Yes, my Diamond!

The yellow Pearl's gemstone began to glow, and the display of some planet was projected.

Yellow: This is the planet Vulcan, your first Gem Colony. It has an abundance of mercury, making it ideal for producing enough Gems to make your court.

Black: I see, does Vulcan have, inhabitants? Non-Gem life?

Yellow: No, White instructed to find a planet with no organic life on it. Until you form your own army, you'll have to colonize such planets.

Black: I understand the concern, but feel it is not necessary. That topic can wait, what vessel shall I be using to reach Vulcan?

The Pearl displayed another projection, this time a pair of legs.

Yellow: This is your personal craft, it was constructed yesterday before you emerged.

Black: A pattern has appeared, Diamond ships are constructed to, be one, correct? I believe your ship, as well as Blue's must take the form of arms, correct? Such a unique design choice, but I can see the available future advantage it holds. Now I should not keep you from your own duties, I shall depart for Vulcan immediately.

Yellow: There is one thing you should do before that.

Black: ...Explain.

Yellow: I suggest you go to the Reef first, White has a gift for you there.

Black: Gift? What is...a "Gift"? I, I do not understand that word.

Yellow: You'll know when you see it. My Pearl will escort you there.

(Some time later, on an unknown planet.)

Black Diamond and Yellow's Pearl appeared within a brightly colored room.

Y-Pearl: Here we are, my Diamond! The Reef, isn't it just lovely?

Black: It's design fits with it being stationed on an ocean planet, it blends with the environment and hides it from potential threats. But this, "Warp Pad" technology is just remarkable, I'll look forward to seeing advancements in this form of transportation in the future.

A shiny orb on the ceiling lit up, and a voice began to address Black.

Shell: Welcome, Black Diamond. I am Shell, your guide to the Reef.

Black: An artificial intelligence? Homeworld technology so far is more advanced than I first calculated.

Y-Pearl: We're here to collect the gift White Diamond has prepared!

Shell: Understood, please follow the illuminated path to the Modification Center.

A row of blue lights appeared on the floor, leading towards one of the large doors. The two Gems followed this path, passing by holographic projections of skinny figures.

Shell: Please feel free to take your time looking through the latest offerings in accessories and appearance modifiers as we make our way to the Modification Center.

Black: They make...accessories for your kind?

Y-Pearl: Yes, all Pearls are made to fit their owner's desires in any way. And if anything should happen, we can also be repaired here.

Black: Hm...they all look very well designed...but I see no need for such trinkets for my own, something with use, with a purpose other than aesthetic.

They proceeded to the next chamber, where inside they found a small, white bubble, floating in the center of the room. Inside the bubble, there was a small, dark gemstone.

Black: So this is my 'gift'?

Shell: Confirmed. White Diamond took considerable time preparing it for you, there's one more detail left before it is truly ready, however.

A square pedestal rose from the floor, with a hand print in place of a button.

Shell: Place your hand on the device, and whatever you desire for your Pearl will be implemented into its gemstone.

Black: It can do that? Just what else are we currently capable of...another time, now...

He placed his hand on the pedestal, and aftet a few moments, the white bubble popped, but the gemstone inside remained in the air. A holographic shell then appeared around the stone, and a voice sounding like the first two Pearls addressed the Diamond.

???: Please identity yourself.

Black: Black Diamond.

???: Greetings, Black Diamond. Please state preferred customization options.

Black: ...Default for now.

???: Default setting selected. Please stand by.

The shell descends to the floor, as it opens and reveals a glowing figure with the dark gemstone on its chest, identically to Black's gemstone placement. Two eyes then formed, and the figure began to...sing.

???: ♫How do you do, my dear Black Diamond? Thank you for bringing me into-the world! I am at your eternal service...♫

In a flash of dazzling light, the featureless Gem revealed her form.

Blk-Pearl: ♫Welcome to your new Pearl~!♫
