Rainbow Dash was the Iron Wing. She was a war hero, the Slayer of Shadows, the Liberator of the Crystal Empire, the Wrath of Celestia. And depending on who you ask, she still is.

But the war is over. There's little need for a pony like her in peacetime. So she keeps telling herself that she needs to adjust, that she needs to find a new role to fill in the world that she saved. But Equestria seems content to let her remain what she has become, even though they have no need of a warrior.

"This isn't how it's supposed to be", is something she keeps telling herself. But every time she says it, the only thing she can reply is, "so what should it be?"

One whole year after the close of the war, and Rainbow Dash still doesn't have the answer.

This story is a sequel to The Lunar Apprentice

Celestia won. Her Royal Guards defeated Nightmare Moon and her army of rogue Lunar Guards. The Shadowbolts were driven underground, and the Lunar Apprentice is dead. And what has victory brought?

Hell.

The Elements of Harmony are separated and useless. The renegade forces of the New Lunar Republic are hidden in the shadows, free to move and strike at will. Confidence in Celestia's rule has been shaken throughout Equestria. Half the Royal Guard is out of commission, and the changeling army is on its way.

Every loose thread is being pulled on; it's only so long before the tapestry unravels.

Celestia may have won the battle, but she also unleashed the Night Terrors. And Equestria may not survive them.

Update 10/14/2015: Featured! Glad Night Terrors is proving to be as strong as its predecessor. A major thank you to all fans and followers!

Stranded on a hostile, alien world, Twilight Sparkle and Rainbow Dash must depend on one another and a fellow alien castaway if they want to return home to Equestria.(originally published on FFN)

With the whole of Equestria plunged into darkness, the once peacfull world is now tearing itself appart with fear. Twilight, Fluttershy, Rarity and Spike are now the only hope the world has.
They choose to leave their home to save Rainbow Dash. Despite loosing their friends because of her they are determined to prove she can be saved from her madness, which is slowly consuming her. But will there be anything to save?

In the midst of autumn's splendor Twilight Sparkle, Spike, Applejack and Rainbow Dash head north to participate in the Hoftston Mare-athon segment of the annual Running of the Leaves.

Yet, as they meet the sea something seems to call Rainbow Dash down, down into the fog and uncertainty that rolls in from beyond the Everfree Forest.

What secrets of old Equestria hide in the deep woods and upon the silent shore?

*Resubmitted following revisions.*

It was supposed to be easy. A simple ambush. Jump a flanking force of Sombra's before they reach the battlefield. Rainbow Dash and the rest of the Wonderbolts had done it a thousand times before. She could do it in her sleep.

But then things go south for Dash, and she's taken behind enemy lines. Everypony knows her fate: to be brainwashed into serving Sombra. But what seems to be hopeless may just reveal more about Dash than she knows about herself.

Discord, for a master of chaos, was actually a very good planner. Despite the confidence that he would bring Equestria to its knees in mayhem, several millennia of experience had taught him to have a back-up, no matter what. And after watching from the sidelines as Princess Luna became Nightmare Moon, he knew he had found an ace in the hole. Despite his defeat, Discord's greatest trick was still to come.

You know what this means: Equestria's greatest Nightmare is back. And this time, she's not alone.

Hey guys, this is my first pony fic. However, I do take constructive criticism well. I can only get better if I know what I'm doing wrong.
