Maiden Thief strolled about the deck of her well-polished ship, twirling her knife between her fingers absent-mindedly. Fay sat on one of the adjoining ropes of the mainsail while watching her best friend and captain walk around with unrest. She fluttered next her shoulder and Maiden stopped her pacing for a moment.

"Hello there," Fay smiled up at the much larger human. "What's wrong, Cap'n?"

Maiden smiled at her pixie friend, then looked off into the clouds. They were sailing high and above sea level into the atmosphere. The floating ship creaked when gusting winds blew against the hull and rocked the metal wings. "Waiting for the pirates."

Fay jingled her butterfly wings gently. "Yes, and?"

Maiden sighed and walked over the the rail, her (e/c) eyes scanning the soft silver vapor that made the air seem ominous, yet gave a slight feeling of serenity. "I am anxious about our meeting with those scullywags" Fay giggled, a stream of small melodious laughs emitting from her.

"Is that all?"

"Well, not really." Maiden impaled her knife into the railing. "I simply don't trust them, even under a white flag."

"Pirates have black flags with crossbones and a skull." Fay pointed out.

Maiden glanced at her friend on her shoulder and saw a smug smile on her soft little face. "Fay, what are you trying to convey?"

The pixie shrugged innocently. "Dunno. I thought you might need some rest before we meet the Mystery Crew. They are pretty stinky and I thought perhaps a small nap would suffice for that nastiness."

"Oh no." Maiden intervened rather quickly. "I want to be up and alert at all times. It is captain's duty, of course. I have my responsibilities, Fay." She gave Fay a pointed look, knowing what the mischievous fairy was trying to avoid. Fay knew it, too.

She leaned on her left arm, fluttering her long lashes at her captain, who didn't break their gaze. "You like him, don't you?" Maiden looked away. "I do not feel anything for that monster."

Fay scoffed. "Of course you don't. That's why we act like pirates, steal like them, speak like th-"

"Stop that, we don't." Maiden frowned her eyebrows at her sidekick. "We're thieves, not bilge rats." A click on the deck stopped her. A young girl walked towards her captain and her second-in-command. Maiden turned towards the black-haired girl.

She nodded her head respectively. "Ma'am."

Maiden grinned at the child. "Yes, Ghana?" The girl shifted and looked down as if she were embarrassed. Maiden waited patiently, but Fay got impatient quickly, being the hot-headed pixie she was, and ordered the Italian thief to speak up. But all the Ghana heard was jingles and sounds.

Maiden shushed her and proceeded the newbie to ask her question. "Go on, child."

Ghana looked up with guilt written over her face. "Uhm, I overheard, um...the Cap'n and Ma'am talking...not on purpose, I just happened to be doing my duties and I passed by and overhead… a few things have been on my mind lately...ever since I joined this good and amazing crew…"

Maiden brightened at her words while Fay rolled her eyes. "Yes?"

"W-well, I was wondering, ma'am…" Ghana paused for a long time. Maiden waited patiently, knowing full well how hard it was for this overly-abused girl to act like around those who have a higher power over her. But what Ghana asked was totally out of the blue and made Maiden space out a bit:

"Are we pirates?"

There was a small silence before Fay's laugh echoed throughout the ship. Passing girls looked on in wonder, then shrugged, knowing they shouldn't walk into business that wasn't theirs. Maiden slumped into a full gaze over the Italian girl's black head, thinking.

It was a long wait before Maiden knelt down and hugged the girl. Ghana flinched, but relaxed into the hug and tightly hugged the captain back. They held onto each other for a while, rocking back and forth, comforting each other to an extent.

"We are not pirates, sweet child." Maiden said quietly. "We are thieves for the island of Gahuna. We do not represent an uncivil character to those around us unless it is evil. Pirates are evil and we will destroy them."

She released Ghana who smiled up at the woman, tears in her eyes. Maiden smiled back at her, stroking her black strands softly. Ghana looked down and hugged Maiden once more, then walked off to complete her chores.

Fay crossed her arms. "Why'd you do that? You know better than to touch that wretch."

Maiden looked after the girl, not looking at the pixie. "We're family. Not servant and aristocrat. We've abolished that from our system, you know that, Fay."

Fay was about to say something before an ear-piercing whistle burst through the silence on the ship. Maiden and Fay looked up towards the main mast, where a teenage girl was looking out toward the sun.

"Pirates on sight, ma'am!" she shrilled. Maiden went for her sword and Fay jumped up to retrieve her own. Maiden pointed her sword at a group of women carrying a box of clothing. "Ladies, gather up the stock and hide it above them sights!" The women trailed away with an "Aye, Cap'n!" behind them.

Maiden continued to shout orders for preparing the ship for landing onto the sea. "Raise the mainsail! Lower the anchor! Cast off the halyards!" The girls flew up and down the wired nets, tying ropes to the poles of the mast, releasing the metal anchor, tightening their safety belts to the main mast's base so they wouldn't fly of the ship when it drops over 100 feet from the sky.

The captain herself did some orders, helping the newbies do their job and adding onto the reason why her crew loved her, despite some of them being much older than her. A blond-haired girl whistled and threw Maiden's impaled dagger to her while Maiden caught it mid-air, barely looking.

"Ready!"

The ship dropped swiftly, many different colored hairs waving wildly in the wind while they clung tight to any support on the deck, ship, mainsails, anything. The drop suddenly slowed and gently set itself about a few feet above the waves. Maiden turned to her crew.

"Dana, Sparkles, release the flag." The girls sprinted off. "We have pirates to meet."

Fay fluttered next to her, her self-made sword clutched tightly in her hands. She nodded at her captain; if anything happened wrong, Maiden would release the signal, and the backup plan would be set. Pirates were KNOWN not to be trusted. So, were the Maiden Crew, but at least they didn't go back on their oaths.

OBTW- Maiden Thief is You. The reader. Mmhmm, you'll see why you're referred to as Maiden later on.
