Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

The 220th Pennsylvania is one of the most experienced and intact units in the Army of the Potomac. Led by their beloved leader, Colonel Lawrence Newman, the 220th shed both tears and blood, as they fight for the unification of their nation. With a cause different for each man, the regiment stood together in the fields, withering bullets as they aim and shoot at men who they knew were fighting for their own beliefs and cause.

Joining one of the greatest armies formed by their nation, they marched on to follow their orders of preserving the Union. They fought battle after battle with the army, having experienced defeat and victories that felt more like a lost than a win, the 220th and its men have seen it all.

But during an engagement with an overwhelming force, they are surprised to see that the outcome was something none of them expected. As the smoke cleared, they find themselves in a quiet and peaceful field, in a strange and foreign land.

In this land of magical land, the men of the regiment find themselves in a new war. A war which seemed so similar to the won fought by their grandparents before them.

(This is the old version of the story.)

With the Union desperate for a victory, the commanding general of the Federal forces conjures up a plan that would hopefully put an end to a civil war that tore a nation apart.

Tasked to set sail as a part of a vast fleet, the 15th Minnesota ends up with the misfortune of being delayed. Setting sail a day late, the ship they have boarded encounters a terrible storm that dwarfs anything these Minnesota men had encountered before.

Soon, the men and officers on board find themselves in a strange land, where everything they know about the world is different and new.
