Amaryllis, an infiltrator for Chrysalis' hive, searches Canterlot for her missing queen, but during her nightly visit to the city she is forced to flee and heads into the Everfree Forest, where she finds an unusual cave, one that ends up changing her fate and knocks her out in process. When she wakes up she finds herself in an unknown world, in a snowy land that rests at the northern end of the continent, in a body that isn't what she's used to having. From there she must relearn the skills of an infiltrator, discover how the people of this new world interact with each other, and either figure out how to get back to her home world, or get used to living in her new environment and killing people to make some gold.

Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

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.

This story is a sequel to Melody of the Future

Two friends separated by circumstances and eras...

Both return to the same time and place, back to their own world, their old lives.

But both have changed greatly, and they did not return alone. And both carry scars of what happened to them, inside and out.

Can these two pick up the pieces of their old lives, and go back to where they were? Or will they perhaps become something more?

Dr. Albert Wily...mad genius, evil scientist, brilliant roboticist, wanted criminal, would be world conqueror, loving father... Wait, what was that last part?

When Dr. Wily wakes up one morning with a tiny unicorn inexplicably clinging to his bald head, he is more than a little flummoxed. Unknown to him, this tiny creature is about to turn his entire life upside down, worm her way into his heart...and make his dreams a reality.

Can you feel the Wub tonight? Mega Man sure will.
