This fic must be Xander/Twilight.

Yes, you read that, right.

Xander, sometime after Halloween season 2... perhaps the next day, gets transported to Equestria. How he does that I'll leave up to whoever answers this challenge. He is ejected, rather powerfully and painfully too, from the in some woods near Canterlot.

This must take place -before- Twilight Sparkle is sent to Ponyville. Two years before. Since Twilight was 18 when she went to Ponyville and she must be Xander's age when they meet now. Xander was born on 02/22/81. That would make him 16 when Halloween season 2 took place in 1997.

On one of her -rare- trips from the library Twilight is searching for some herbs and stuff in the woods. She and Spike, the dragon not the vampire, find an unconscious Xander where he hit a tree when he came out of the . Up to the author on how bad he is hurt from impacting that tree now.

---

Xander is not the only thing to come of the . Some vampires and demons did too in many different places. The ejection points of the were random then.

Up to the author to decide how many vamps. What types of demons and how many. And if any main-character villains were transported.

---

Twilight has never seen anything like Xander and takes him back to Canterlot. Princess Celestia is informed, and has no idea what Xander is either. Having never seen anything like him before.

Xander wakes up to find Twilight watching over him. When she speaks he (can act normal, freak out, or make a witty remark -author decides this-). After calming down a little Xander talks with Twilight.

Up to author to decide how Xander reacts to learning he is on alien world populated by talking ponies.

Over the next couple of years Xander and Twilight grow close.

During those years the vampires and demons have been making a mess and Xander and Twilight have been dealing with them. Xander uses his Halloween soldier knowledge. He also explains how to build firearms. Which are very useful against vampires with the aid of some magic bullets. Especially ones blessed by Goddess Celestia.

When she is 18 on her eighteenth birthday, Twilight gives Xander her virginity. Xander asks Twilight to marry him. Twilight says yes, for about 5 minutes straight, and Xander is glad that she has accepted.

Later on when she is in the library at her place then and informs Princess Celestia about her concerns over Nightmare Moon, Celestia orders Xander, Twilight, and Spike to head to Ponyville to oversee the Summer Sun Celebration... and make some friends.

Cue episode 1 and 2 of Friendship is Magic, only with Xander included along as Twilight's boy(colt)friend/fiance now.

Nightmare Moon has recruited some vampires and demons too. Who love the idea of eternal night. Getting through the Everfree Forest will not be as easy as in cannon.

Of course unlike cannon there is a weapon packing Xander coming along.

Xander does a good job mowing down vampires and demons and gives Twilight and her friends time to reach the castle right now.

Xander joins in the Elements of Harmony. And adds a seventh Element. The Element of Humanity.

As a result when she is restored Princess Luna is a human.

Big sis Celestia does not know what to make of this.
