Rated E to try and achieve TV-Y. A CHU (content heads up) may be needed on chapters that get a little iffy about that.

NOTE: I've separated myself from this work. If you want to see this done another way, look near the end of this other work, A Changeling's Christmas Catastrophe.

EDIT: After writing the note above, I noticed I took several elements from this story out of consideration. I still separate myself from this work, but it's not nearly as blind of a decision as initially.

This story is a sequel to The Lost Changeling: Taken it Back

Carina comes to Equestria early for Hearth's Warming, but is pulled out of the festivities midway through, prompting Carve to come to Carina and her family up in Wisconsin. However, all the celebration is put on the line when Carina experiences a life-threatening conceptualization.

Arada, Mat, and Alo. These three changeling nymphs heard about what had unfortunately happened. However, they refuse to believe that they will no longer be able to see Queen Areola, and in turn venture off to search "for her actual location". But after traversing the South Luna Ocean, they finally meet land in a paradise-like region named Comania. However, that view is put to the test when they lose the ability to speak either language they'd learned, as well as an unfamiliar type of child finding them in... the Marble Forest.

The new year has nearly started, so naturally it's a decent time to reflect on what's happened to far for Carve. However, throughout the last part of the most recent and crazy year, nearly no one from Las Pegasus has ever heard about Rolling Acres, nor any of the stand-in changeling queen's role in helping Equestria accept a willing addition to its alliance.

For New Years, meanwhile, a unicorn from Manehattan is touring Las Pegasus and meets up with Rusty, Pane and Carve. As the three notice his cutie mark, it opens up the door to letting the public know about Carve and her friends. Here's hoping how well received this plan gets.

Greta Scone Corner has been forced into liquidating, thanks to Equestria's economy collapsing. When Carve finds out through someone who looks nearly identical to Spike, she, Rusty and Pane all settle on finding the root of the economic cataclysm.

After three days of settling down, Chrysalis finds a necklace on one of her visitors, and requests to have it. What the necklace unveils is two letters. One for Carina, and one for Chrysalis. Following Carina's visit to the hive, Chrysalis decides to do more in taking the second chance she's been given. But what way should she go about that?

Thorax is a king, a new king in fact, of changelings, having recently overthrown Chrysalis. However, after a session regarding a wake up call he was notified of ends, he leaves to walk about the hive, oblivious to the future of his title.

This story is a sequel to The Lost Changeling

One hundred and sixty moons prior, Carve had moved in with Rusty Flashlight. The two of them, along with Pane Fall, have explored far and wide throughout Equestria. However, three days before Nightmare Night, Carve pays a visit to Rolling Acres, a visit that she will never forget, especially when on said holiday, she is told of a parallel she needs to help undo for Chrysalis.

(Reading The Lost Changeling is heavily advised in order to understand this story.)
(This story is written with regards to recent events within Rolling Acres.)

Where does one expect a changeling to land after the failed Canterlot invasion? The hive? Somewhere throughout Equestria? Carve isn't sure where she is or how she will make it out of her unintended destination, that is filled to the brim with negative emotion, until she finds an adventurous pony roaming around as they are about to go on an adventure unlike any other before.
