Twilight Sparkle and Rainbow Dash Find themselves in trouble, with their lives on the line. Will they get out alive?

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.

Equestria is growing, and magical savant Twilight Sparkle is disgusted by the crime and corruption this change has brought. Her life is changed forever when she discovers the Death Note, a notebook with inexplicable and deadly powers. She uses this book to pass judgement on those she deems unworthy of life, aiming to create a perfect world free of crime. But when the two Princesses put their best pony on the case, a mysterious detective known only as L, a psychological game of cat and mouse erupts between the two.

A horrible Cataclysm has turned all of Equestria into a Wasteland of barren ash and twilight desolation. The Sun and the Moon have been destroyed. Everypony has died--including Princesses Luna and Celestia. But one pony miraculously survives; she is a lone wanderer, the last of her kind, surrounded by menacing creatures that hate her. She navigates the Wastes in an airship and scavenges off the blighted landscape to keep herself alive.

Then one day she meets an old companion who grants her a gift, the chance to go back in time to the warm and sunny days of Ponyville, where her dead friends live in happiness. How far will the last pony venture into this joyous age of Equestria, even if she fully knows that there is no way to change the horrible fate of everypony she loves?

2013 Edition: Smaller Chapters, Better Grammar, and a Few New Scenes

(A shout-out to Vimbert, pre-reader and gentlecolt)

A heated confrontation with Celestia over her portrayal as Nightmare Moon and her sister's authoritarianism leads Luna to search for answers about the past, unwittingly tangling Twilight and her friends into a cosmic struggle between order and liberty. The tragedy of the past bleeds into the present as the Royal Guard, led by the (in)famous Captain Braveheart, pursues the moon goddess as if the fate of the world depended on it. A tale dedicated to the history and government of Equestria, the psychology and political/moral philosophy of the characters, and especially that amorphous and mysterious force that so many seek yet so few gain: power. What is its nature, what drives us to pursue it and keep it? What does it mean to be a leader, a princess, or a goddess at that matter? These are but a few of the questions the characters must struggle with in order to restore harmony to Equestria. This story tries to bring an edge of realism to the political organization and history of Equestria. If you're seeking utopia or dystopia or extremes of any sort, it's not here. .

What's it like to live in Canterlot, home of the princesses, assorted renowned celebrities and sophisticated ponies?

Well, it all comes down to who you are, really - and if you happen to be a fairly ordinary earth pony, you can get on with life quite easily with few distractions.

But what happens when life plays you an interesting hand, and suddenly you're thrown into the spotlight?

This is a tale of the everyday, and how it can turn from ordinary to extraordinary with a twist of chance.

This is a tale of friends, of laughter, of love and of life.

This is a tale of who we are, and how we got here.

This... is Sketchy Salad Symphony.

Twilight lives a comfortable, expected life with the security of being surrounded by her mentors and friends. As she grows into a model unicorn, a dangerous being takes hold of the volatile Brood and drives them to war, breaking a long period of peace. After years of preparation for a higher order, Twilight is chosen to ascend beyond that of a typical sorcerer in a mysterious plan to counter the impending conflict.

During her dark, trying mission Twilight will discover a caged soul and unknowingly set them free, gradually acquiring an affinity for the darkness as a result. As she struggles within deepening conflict, she must push on and fight for what she believes in. With manipulation, deceit, and betrayal storming around, will she be able to contain herself and protect those she loves, or will she succumb to the creeping darkness and abandon everything she stands for?

The Elements of Harmony, rather than destroying Nightmare Moon, separated Princess Luna from her evil side. Free from her 'weaker' half, Nightmare Moon sets her sights on a world ravaged by bigotry and war to establish a kingdom of her own-Earth, but not the Earth that we know.

A crossover between My Little Pony: Friendship is Magic and Code Geass.

A visitor arrives in Equestria, bearing a wealth of knowledge and a troubled past. The Mane 6 are quick to befriend the stranger, who helps them to discover what they truly value in life, and how to achieve it.

But learning to overcome their fears and achieve their desires comes at a steep price, paid by their innocence.

Mr. Horse's pet courier has been murdered and his property stolen. And while the price on the killers' heads is good enough to get any bounty hunter's attention, it's the bonus for returning a silly little poker chip that draws Dead-Shot in.

A pony could retire on that kind of jackpot...

A communication scholar from Canterlot, a mailmare from Fillydelphia, and a zebra diplomat in training, brought together by a hunger for knowledge, embark on a journey of discovery to the mysterious homeland of the dragons.
