Before I start this fanfiction, I want to point out one of Lucina's endings: "Lucina disappeared after whispering these words to her infant self: "Yours will be a happy future." Did she journey to another land or back to her own time? ...No one knows for certain." This ending begged the question: what did happen? This is my fanfic on what happened. It begins now.

"Yours will be a happy future." Lucina said to her younger self. She then looked up at her parents, Chrom and Sumia. Lucina walked to them and hugged them.

She then walked out of the castle she was in and saw something familiar. It was the time portal that had brought her to this time. She walked in it, hoping that a new, altered future with no chaos would appear.

In a new future, a portal appeared, and out came Lucina in the same place she entered the portal. She walked into the castle and what awaited her was a man very familiar, but looked a bit older. "Lucina! You must be back from saving the world ten years ago! It's so nice to see you!" This person Lucina now recognized as her father, Chrom. "Now, come upstairs with me. I have a little surprise for you"

After walking up, Lucina saw her surprise, a big family reunion. It had her mom, Sumia, her younger sister, Cynthia, her aunt, Lissa, her uncle, Lon'qu, her cousin, Owain, and… Gerome? Gerome wasn't related to Lucina in any way, he was Cherche's son. So Lucina asked "What's Gerome doing here?"

"Why is Gerome here? This needs a little bit of explaining. Because you came from a different future and altered the past, some things that never happened did happen because of what you did. One of these things that happened here was you getting married to Gerome and having a daughter named Arabella." said Chrom. He then walked away for some reason.

Lucina always had a crush on Gerome, but she never expected this. "Where is Arabelle? I'd like to see her." said Lucina.

The moment she said that, Chrom came back holding something small. Lucina took a look at it, and it resembled what she looked like ten years ago. It was Arabelle. Everyone crowded around her and said "Aaaaaaaaaaaw!", except for Lon'qu, who just said "…..Cute."

"Chrom." said a voice near a window. "We have an army outside here that isn't Valm or Plegia, and it isn't any Risen either.

Chrom walked to the window, where the voice, who turned out to be Frederick, was standing. "They look like the Tagonians." said Chrom. "Wait a minute! Tagon are our allies! Not our enemies!"

"I've always found the Tagonians suspicions, milord."

"Well, I guess I can agree with you. Now, get the troops."

Chrom then turned around. "Sumia, you watch Arabelle."

"As you wish." said Sumia.

"Milord," said Frederick, who had just gotten the troops ready. "They are ready for battle."

"Okay then." said Chrom. "Let's move out!"

And that ends Chapter 1. Special thanks to Miiverse users LadyPembroke1485 and Varelk for giving me some of the ideas that were used/will be used later in this fanfic. Stay tuned for next chapter. Until then, goodbye.
