Love is one feeling that can never be taken from someone's heart. No matter how many years of separation, no matter what wrongs were done in the past, no matter how much enmity exists between two ponies, love will always stand; at least that's what Nightmare Moon is hoping for. 700 years ago was the last time she had seen her sister Celestia, and her departing words had simply been 'I love you'. Now, after so long, Nightmare Moon's heart longs for its other half; and thus, she has brought Celestia back from the far away, magically void lands she cast her to so long ago. Now, she wonders if her sister will ever find it in her heart to forgive her for what she's done, and if their lives together can ever resume as they once had.

Takes place 300 years before when Luna would have returned from her banishment to the moon, and takes place in a universe where Nightmare Moon was never banished in the first place.

Pinkie Pie wants some apple strudel, and by Celestia, she's gonna get it!

Bad things happen. Good things too, but mostly bad things. Sometimes, your wagon gets destroyed by a giant bear. Sometimes, you make a bad reputation in some town you promise to never visit. Sometimes, you compulsively splurge most of your savings on some fancy-looking trinket that you won't even wear. But getting sucked by a fiddlestinking portal to another world?

Well, not unless your name is Trixie.

[A Familiar of Zero Crossover]

The Empire of Harmony is a unified coalition of various races who joined under the banner of Princess Spike, who lead the combined forces in a battle to defeat a powerful tyrant, and has since been the world's biggest and longest running society.

Big Macintosh is an Earth Pony visiting the city of Canterlot, the capital city of the Empire, on urgent business (and a little sightseeing), however little does she realise she's going to end up at the centre of a race to save the world as an ancient and powerful enemy returns from the past, filled with anger and hate....and power.

When Twilight was born, her parents weren't who she thought they were. Regardless, the two god-like entities loved her dearly, not wishing to depart with their beautiful daughter... However, after an incident involving an malevolent entity, that wanted her for some dark plot against all mortal beings, they agreed to disguise and send her away. The decision becoming more painful to both sides, as the link keeping the two god-like beings together, had been cut.

Twenty years later, during an attempted spell, Twilight had been attacked by the entity once more, taking its new chance at her. With its link to her world cut, only able to manipulate the spell, the Entity decides to send her to a different realm, where he has his pawns lying in wait to capture the valued prize. Now, the princess finds herself fighting along side the web-slinging hero, Spider-Man. Though, they have another ally that had been sent to protect Twilight at all cost, even if death comes for him. This protector being something neither teens had ever seen before in their life time...

An Astartes of the XV Legion, one of the Thousand Sons.

When a pony named Magnus accidentally comes to Equestria with his rather violent brother the two rush to find a way back to their own home. However, they first must get help with the local royalty which proves to be harder by the minute with how much Magnus's brother keeps trying to kill local ponies out of annoyance.

Teen for violence and language

At one time, Mount Olympus was the home of the Greek gods. Then they let the first pony in.

A scientist wants to take Spike and study him in hopes of understanding dragons; however, her questionable methods make Spike refuse. The scientist counter-argues that Spike is not a pony and the same rights given to a pony, do not apply to him. A trial is commenced with Twilight as Spike’s defense attorney and Cadence as the unwilling prosecutor; Twilight must prove that Spike does indeed deserve the same rights as any pony. Or else, Spike is a lab rat that she will never see again.

This is a fanfic inspired by a Star Trek: The Next Generation episode The Measure of a Man, directed by Robert Scheerer. If you haven't seen it, I highly recommend it.
I want to thank the person who brought me into the fandom for helping me truly refine this idea and truly give it life. You know who you are!
I will say right now, updates for this fanfic may be highly irregular until I take care of certain obligations, but I promise not to abandon it until it's done.

Spike's got three whole days to himself while Twilight is away at the Crystal Empire. Three whole days to be independent and free to do whatever he wants.

Or he would have, if a female dragon hadn't mistaken him for an abandoned hatchling. Now he's been snatched up and taken to her home to be "properly cared for."

Stuck in a cave with an overly-protective dragon intent on mothering him...maybe he should have just gone with Twilight.

Thanks to QueenCold for letting me use this picture of theirs as cover art!

Twilight's gone. In her battle through time, she died, a victim of an alternate timeline. Starlight is defeated, but at what cost?

Spike's lost the pony that's always loved him, the one who acted as a mother, sister, teacher, and best friend. Now he's in pain... but he's not alone. Because Twilight's friends have vowed not to let him become an orphan. In place of one mother, five will now raise him.
