This story hops from different alternate-universes so I will label them as "Main Universe," "Alternate Reality," "Alternate Family," "Alternate Future," "Alternate Universe," and "Dreamland". And now without further ado…
Zuko: I quit!
Me: B-but why?
Zuko: Because every time you write a story, something bad always happen to me.
Me: No I don't.
Zuko: Oh yeah, well, your very first story was an exception, but the one after that for a short time I was a spider-monkey!
Me: It was only for two days…
Zuko: And there was that one when I was a robot!
Me: That was unofficial T_T
Zuko: And the ones where I was either a Neko or a dragon! And there was even an entire story about me turning into different things.
Me: Oh yes, the Thirteen Curses, *snickers*
Zuko: And I always have no choice, but now I am finally free of your grasp!
Me: Not exactly. I have insurance on you.
Zuko: What are you talking about?
Me: *grins* Oh LULU!
Zuko *frightened*: Who's the creepy dude with the mask?
Me: Unlike you, Zero will always follow me because I'm the author!
Zero: Lelouch vi Britannia commands you: You will obey Mitsuko's orders.
Me: Now that I've gotten rid of the annoying firebender… On with the story! (P.S. If you don't know who Zero is… I grieve you.)
Be Careful What You Wish For

Prelude [-Main Universe-]
It started as another average day at Zuko's beach house. They had been hiding there preparing for the comet for about a week now. The prince had just given his pupil a short break and was heading towards the small earthbender. Toph, meanwhile, had been entrancing Katara with a story her mother once told her about a Spirit Princess who saved an entire town from a tyrannical dragon. Zuko glanced at the girl, knowing very well that the story was an old Fire Nation tale that went nothing like the way she was narrating.
The girl that they had saved from the Boiling Rock (Suki was her name?) came and whispered something in Katara's ear. The girl groaned and said, "Guys, we need to go shopping."
Zuko cocked his head slightly, "But we have plenty of food, don't we?"
"The last of the meat somehow disappeared."
Before going to the marketplace, they had disputed over whether to blindfold Zuko to prevent identification since his face is the most well-known all over the world, or to leave him with Suki. Zuko had told them that he and his sister had spent a few days there with no one ever figuring out who they were, however Katara had insisted that he'd wear a blindfold to shield his face.
As they were walking, Katara was chatting to Aang about the story that Toph had told her, and Zuko, finally recalling what he had to say, whispered in the small girl's ear, "You do know that the story doesn't go that way, right?"
"I know that and you know that, however Sweetness and Twinkletoes don't know that."
"Then why didn't you tell her the actual story?"
"The story was too dark and creepy for my taste. So I lightened it up a bit, no harm done."
"I guess you're right," Zuko shrugged. Sokka rushed over to them from a stand and said, "C'mon guys, look at this! Umm… no offence Sayuri and Zu—Lee! Zu Lee." Despite his eyes being covered by a piece of cloth, the firebender attempted to glare at the bumbling Water Tribe boy that almost had gotten his cover blown.
He felt a small tug at his arm and realized that Toph wanted him to follow her. "So, what is that, Wang?" Aang asked.
"It's a wishing star!" Sokka exclaimed, Zuko had heard of those before. Legend has it that if five people made a wish at the same time, their wishes would be granted…and there were five of them. "Let's go and wish!"
"Wait a minute, you didn't buy it, did you?" Katara skeptically asked her brother.
"It's a once in a lifetime opportunity, Safire! Isn't there something that you'd wish for?" Everyone in their group had a thoughtful look on their faces and Katara reluctantly agreed.
The woman that sold it to Sokka explained to them how to use it, "But remember, every decision you make has a consequence."
Sokka did the countdown and they all made their hopeful wishes.
