This story is a sequel to Rescue on Diamond Mountain

Story seven of the Savage Skies series. The first months of Dawn's stay in Ponyville have been tumultuous, to say the least. Fortunately, winter is coming, not only offering the colt respite from his enemies, but also giving Dawn the opportunity to enjoy the season with his new friends and family. Little does he know that this is to be a season of many firsts for him.

Meanwhile, a new pony has come to Ponyville in response to Twilight Sparkle's call for research subjects. Unfortunately, this stallion's past experiences have left him bitter and paranoid. It will be up to Rarity, of all ponies, to make this unexpected guest feel welcome in Ponyville and heal the wounds in his heart.

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."

Dawn Lightwing has overcome many trials since moving to Ponyville. However, his past and the ponies that haunted it are not as far behind him as he would like to think.

Twilight Sparkle must deal with a different shadow as she travels to Canterlot in order to learn more about the mysterious Eyes of Nightmare, as she must contend with the Noble Court, who live in the shadow of the Royal Palace itself, its members planning to use Twilight and her friends to advance their own ambitions, stopping at nothing to have her under their influence.
