Welcome, dear readers, on my first ever 100 themes challenges! I have decided to use AngieChild's list, and as for the pairing, it will be TerrAqua.
Some chapters will be independant, others will be linked. Some will take place in the Kingdom Hearts universe, others in alternate universes.
Oh, and I won't write the chapters in the order given. The length will be different from one chapter to the other.
I'll make a cover as soon as I can.
Enjoy !

I. Introduction

It should have been a normal day, spent training with his wooden Keyblade, as always. His days weren't really that different, following the same rhythm, indefatigably. Not that it bothered or bored him, or that he dreamt of a different life, but Terra had to admit his everyday was rather repetitive.

Thus, he didn't quite expect that this would be messed up suddenly ; neither did he expect that the perturbation would take the form of a little girl with long blue braids.

"Terra, said Master Eraqus, meet Aqua. Just like you, she can wield the Keyblade, and will be living with us from now on. You shall train together."

Said Aqua had gauged him with her deep ocean gaze, before giving him a genuine smile, that the boy had returned after a second of hesitation.
Eraqus gave her a tour of the domain, before putting her in his young apprentice's care, as he had to speak with a certain Yen Sid.
There was an awkward silence between the two kids, as they sat outside, on the grass.

"Have you been here for a long time?"

The question surprised Terra, but he rapidly answered :

"Two years.
- Woa! You must be very skilled, then.
- No, not that much... I still have a lot to learn, if I want to become a Master one day."

Aqua nodded.

"How about you? Where do you come from?
- A world called Twilight Town.
- Oh..."

Terra's eyes lit up. He loved to learn more about the numerous worlds surrounding them; he only knew the Land of Departure, as well as his own homeland.

"And how's it like?"

His new mate sighed with joy, and decided to give a good description of her native city.

"It's a wonderful place, with green hills, buildings of red bricks, and a sky that's always in marvellous orange shades. The air is always pleasant, and the people nice. And there's the sea."

She closed her eyes.

"I love the sea. And the sand is so soft, and there's even seashells! With my big brother, we'd always pick up some, and we'd make necklaces. Here, look."

The little girl took a pendant from under her shirt ; it consisted in a star made out of five seashells, hanging on a leather tie.

"And you? How's where you come from?
- Completely different! My world is called the Land of Dragons, and I was living on a small village lost on the mountains."

Aqua repressed a small scream.

"But that means, you had snow?! I always dreamt of seeing some!
- Yes, it was often snowing.
- Is it really cold? And like a white coat?"

In fact, Terra didn't enjoy snow that much, especially since he wasn't very resistant to the cold. And after seven years spent sledding or throwing iced balls, it had lost some of its magic. But in front of Aqua's amazed gaze, he couldn't bring himself to tarnish the image of something that mattered to her.

"Exactly. It's very pretty, especially on mornings, when no one has stepped in it yet and it's all over the ground. But I liked going to the city next to mine better, because there was a very colorful market and lots of shops."

As he thought about it, the smells, the textures were coming back to him, watering his mouth.

"You'll take me there one day! And I'll show you my town. I'm sure you'd like its speciality, sea salt ice cream!
- Yuck! It must be too salty!"

The blue haired girl stood up, looking offended.

"You gotta taste before saying you don't like it!"

Terra broke into laughter, and his mate followed him.
Not very far, Eraqus couldn't help but smile, delighted that his protégé at least had a person his age he could trained with and, most importantly, bond with.
Terra had a great potential, but he was only nine, and being a Keyblade bearer probably weighted more on him that he'd let on; having a friend could only benefit him.
