Equestria finds itself caught in the cold war between the United Federation of Planets and the Klingon Empire. Can friendship prevail, or will this cold war turn hot, despite their best efforts?

This is a crossover with Star Trek, taking place in late 2269 of the Prime timeline, during the fourth year of the five-year mission of the original television series. It's not a crossover with the movies made by J.J. Abrams. It is mid-season five or so for Friendship is Magic. it is my humble offering for the fiftieth anniversary of Star Trek, which debuted September 8, 1966.

Thanks to FoalsHalf for being essentially my co-writer/sounding board, and to all those who have helped with proofreading and editing.

Celestia prepares for another routine day at the castle with the recent addition of teaching her new, young student. However, an impromptu structure made from books causes a slight change of plans.

Inspired by the cover art and it's description, both used with permission from the wonderful Nova Quill.

When Twilight is stolen from her home, fate intervenes and brings her straight to her destiny. After growing up sheltered and loved by the spirits of the Tree of Harmony, Twilight will grow into her place in Equestria like never before while she searches for the family that raised her and gets to know the one she's lost.

(Unapologetically OP Twilight, if you’re going to nitpick that point then you are welcome to leave at any time.)

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.

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?

Part of the PWNY-verse.

Edit: New Cover Art by Spitfire-Sos over on Deviant Art! It was a prize from a raffle, and I love it so much!

Equestria has seen their fair share of dangers and threats made to their land by gigantic monsters and power-crazy lunatics. From all of these threats, the Elements of Harmony have been at the ready to combat them through the unbreakable bonds of the magic of friendship.

However, a new enemy bearing incredibly lethal weapons threatens to leave the Elements helpless against unprecedented violence. When one Element and two others are taken hostage, a group of elite soldiers contact Princess Celestia to offer assistance. They're professional and more than capable, but Celestia fears they may have ulterior motives. Not to mention, there's the fact that they come from another world.
