It all started with a simple question. "Can the portal go to other places besides Equestria?

The answer turned out to be "No, but we might be able to make one that can."

When their research is complete, Sunset and Twilight are pulled into an adventure in another world, where they meet even more doppelgängers of themselves. But their alternate counterparts may reveal some things about themselves they never knew.

Here I am, thrown in as a changling Queen far before the Canterlot invasion, watch as I- A: make my whole race terrified of me B: overthrow a changeling god! C: die, a lot. D: all of the above.

What do you think?

Suddenly finding herself in hell, Twilight is presented with one fact: for the rest of eternity, she's stuck in a library holding every book possible. She's expected to organize them and is allowed to read them.

What makes this hell, again?

Now has two Spanish translations, one by SPANIARD KIWI and another by Pugg-Senpai.

For a long time, Twilight could feel it; a sense of emptiness she couldn't explain. Now that she's a princess, that feeling is stronger than ever. She finally decides to bring the matter up with Celestia. In response, Celestia gives her an old book.

The contents of that book will change her perspective of the world... and her beloved mentor. Just accepting the truth is a challenge. And after that?

She has to make a decision.

Once upon a time, a merchant was going to set up a stall in a convention to sell enchanted artifacts to cosplayers in order to send them to a variety of iterations of a particular world for honestly rather stupid reasons.

He was probably expecting somebody familiar with the RWBY series--especially Blake Belladonna.

He was not expecting me.

So, yeah, things got off to a weird start...

This story is a sequel to Steel Soul

Sweetie Belle has discovered a secret. She's spent a few months keeping it to herself, but the nightmares she's had have convinced her it might be time to reveal it.

Sequel to Steel Soul.

General Iroh. Fire Nation hero. First born son of Fire Lord Azulan. The Dragon of the West. It was thought he would be the greatest warrior in the history of the Fire Nation.

But all that changed when the war claimed his son's life. This changed him, and he turned his back on the war.

This was a necessary event. Iroh had a role to play in bringing balance back to the world...but to play that role, he first had to be broken down, so that he could be rebuilt. This truth was self evident in the spirit realm.

But one particular spirit felt this was unfair to Iroh. The wheels of fate are cruel to those caught in the gears, but this particular spirit felt that Iroh deserved kindness. And so this spirit sent Iroh one who would help him to rebuild himself.

And so, shortly after his son's funeral, Iroh would find a creature sent by the spirits, the likes of which he never would have imagined...a pretty pink pony princess.

Somepony to love...and be loved by.

Then there is the mirror portal to Canterlot High, which she and the senior staff of the Harmony had discussed at one point in their journey, filling the Princess' curiosity. It has been closed for around two millenia, so who knows what could be on the other side?

And then there is Discord. He seems to know something, and urges the Princess through.

All this, so the Princess can meet some very enterprising people. Discord has brought the popcorn.
