Zac was laying on the wing of his ship, arms crossed behind his head as he watched the sky darken. The feeling of dread remained ever-present, similar to how it was the night he lost everything. As the thunder rumbled and the wind picked up, he suddenly found himself thinking back to the not-quite-dream he had just hours before Darkness descended three years ago.
He had awoken to find himself in the midst of a void, an aquamarine light from above being the only visible source of light, as if he were deep underwater. Despite the strange surroundings, he couldn't bring himself to be scared, more curious than anything. As he took a step forward, light suddenly washed over him from beneath, spreading out into a large circle before it faded to reveal a beautiful mosaic of stained glass. The scene beneath him was one that was all-too-familiar: deep blues, blacks, and points of yellow and white came together to form the skyline of the city he was born and raised in, one he loved with all his heart. The ground rumbled as three pedestals rose from the ground, each bearing a different weapon: a sword, a shield, and a scepter. As he approached each one, a disembodied voice echoed in his head:
[The Power of the Warrior. Invincible Courage. A Sword of Terrible Destruction.]
[The Power of the Mystic. Inner Strength. A Staff of Wonder and Ruin.]
[The Power of the Guardian. Kindness to Aid Friends. A Shield to Repel All.]
Zac stared at the three weapons for what felt like a long time. Somehow, his heart knew that he not only had to choose one, but which one he was going to choose. He reached out and took hold of the sword. The pedestal it sat on disappeared as the voice echoed again:
[You have chosen the power of the Warrior. Now, you must choose that which must be lost.]
He glanced between the shield and the scepter, then down at the sword in his hand. 'Wonder and ruin' sounded cool, but he thought back to something his father had told him, that he was strong so he could protect others. With those words in mind, he decided to give up the scepter. As it vanished, the voice spoke again:
[You have chosen the power of the Warrior. You have given up the power of the Mystic. The shape of your Heart is set.]
As the pedestals sank back into the mosaic, he turned and found himself face-to-face with three shadowy creatures as they rose from the ground. He took hold of his sword and stepped toward them. However, as his foot came down, he suddenly fell forward as he stepped into shadow. The world went dark and he lost consciousness for what felt like only a moment. When he reopened his eyes, he found himself standing on the rooftop of his father's garage, the same place he would go to whenever he needed to think. The city stretched out before him on all sides, lights shining brightly to keep the dark of the night at bay while the sky stretched out in an endless sea of stars.
He turned and suddenly found that he wasn't alone. Leaning against the door to the stairwell down was his father, a tall, well-built man with salt-and-pepper hair and a matching beard, the same easy smile as Zac's on his face. To the north, standing against the railing, was his mother, a young woman with auburn hair and glittering blue eyes. And to the south, a girl his age. She had short, wild-looking red hair, forest-green eyes. She wore a white t-shirt underneath an open light blue-and-white checkered open button-up and distressed jeans. The strange part, however, was that Zac didn't recognize her, yet he felt a powerful connection to her. Deciding to leave that mystery for later, he turned to his father and approached. Before he could say anything, his father spoke up, saying in his deep, rumbling voice, "What do you want out of life, son?"
The question confused Zac, yet the answer was leaving his mouth before he could even really think about it. "I wanna see new sights. To experience everything I can." His father smiled, as if satisfied by this answer, then closed his eyes. Sensing he wouldn't get anything else out of his father, Zac moved to his mother. Like before, she spoke up before Zac and asked, "What do you hold most important?"
Like before, Zac didn't hesitate in answering, "My friends and family. Mom, what's going on?" His mother didn't reply, however, wearing the same satisfied smile his father had. He waited a moment longer before he moved onto the girl, who stood there with her arms crossed and a confident grin on her face. When he approached, she asked, "What are you so afraid of?"
"Losing--" you. he nearly said, only managing to stop himself through sheer force of will. He didn't know her. He had never even seen her around town, yet he could already tell that she was one of the most important people in his life. Yet it still seemed strange to him to flat-out admit that, even if this were a dream. When he opened his mouth again, he managed to say, "Losing...the ones I love." She arched an eyebrow at this, but smiled nonetheless. Once again, the world went dark.
When he reopened his eyes, he was standing on another stained glass moasaic. This time, the subject was himself, his eyes closed as if in slumber. In his hand, he held a strange, key-shaped sword and the background was of that same skyline, yet there were also images accompanying it. Three people were featured: his parents and that same girl. Before he could wonder about it, he heard the disembodied voice from before:
[The Darkness within is just as dangerous as the Darkness without.] He looked behind him and saw a hand slowly reach up out of his shadow, followed by another. [But, fear not.] A shadowy replica of Zac with yellow, glowing discs for eyes began to pull itself out of his shadow. [No matter how deep, how all-consuming it may seem...] The shadow version of himself reached out and a corrupted version of the sword in the mosaic appeared. Just as Zac began to wonder how he was going to fight or get away, the sword from earlier reappeared in his hand in a blinding flash of light. He looked from his weapon to the dark version of himself, then gripped his sword tightly.
[A strong Heart will always prevail over the dark.]
With a yell, Zac charged as his dark copy rushed towards him. The last thing he remembered was the sound of their weapons clashing.
Zac slowly opened his eyes and saw the massive sphere of darkness hanging over the island. He sat up and narrowed his eyes as he said, "I thought so. That explains this dread in the pit of my stomach." Despite having an answer to that, however, a new worry settled over him. It's happening too fast, though. Every other world I visited, I got there early enough to do something about it, but I haven't seen a single Heartless since I got here. It's just like what happened with my world... His thoughts were interrupted by the sight of Heartless appearing in the sand beneath him, surrounding his ship. The small, impish creatures made him chuckle. "Really? Shadows? Come on, you're underestimating me so much that I actually feel offended!"
The moment he dropped down from his ship, one of the Heartless lunged at him, yet he easily caught it by the face before he slammed it into the sand, making the ground around him rumble slightly. He had always been strong, but over the years since awakening his power, it seemed he had only grown stronger. As he straightened up, the shadow he slammed to the ground dispersing, sand and stone began to swirl around his hand before it condensed. Light flashed from the earthen mass in his hand before fading away to reveal his weapon. It was long, the wide bronze blade alone being roughly four feet, with a single, sharp leading edge while the reverse side had an almost jagged look, giving it the appearance of a modern pin-and-tumbler key. The grip was enclosed in a full, circular guard, silver in color, and a bronze-and-silver fleur-de-lis dangled from a thin chain attached to the end.
As Heartless swarmed around him, Zac took a deep breath, centering himself as a faint, orange glow enveloped his body. He hefted his weapon, his Keyblade, over his shoulder, as if he were up to bat in a baseball game, then swung with all his might. While his Keyblade didn't make contact with anything, the earth rumbled before stone spikes suddenly erupted in an arch in front of him, Shadows fading as they were impaled by the spikes. Another Shadow leapt at him before he could recover from the swing, but he was ready for it. Instead of trying to stop, he used his momentum to spin in a full circle before he brought his Keyblade down on the Shadow from above, cutting through the Heartless and shaking the ground as his Keyblade slammed into it. He cracked his neck as he pulled his Keyblade from the ground and rested it on his shoulder. "I've gotta wait for some passengers," he said to the Heartless. With a grin, he added, "Feel free to keep me entertained until then."
