This story is a sequel to Lost into Shadow

The impossible has happened, through all the pain and darkness, Twilight Sparkle succeeded in her impossible mission...mostly. King Sombra is still plenty rough around the edges, but despite being an old dog he's making an effort to learn new tricks. Where will this new way of life take him? He has absolutely no idea, but with his queen to guide him, what could possibly go wrong?

You know the story of Nightmare Moon. Or so you think. What many do not know is that before she was banished, she had a foal of her own. Many people do not know, not even the Princess. Which is good otherwise she would have seen right through my disguise. My name is Shadow Moon but everypony over the past thousand years have called me Twilight Sparkle and this is my story.

Some ponies just don't have any luck.

Twilight Sparkle is one of them.

Sure, other ponies might say she's the luckiest pony ever, being the personal protégé of Celestia, a well known pony in all of Equestria.

What they don't know, Twilight Sparkle isn't Twilight Sparkle.

Everything was perfect, her cover has never been blown. Until that one fateful day, the day Shining Armor, Twilight's brother, should have been married, the day of the changeling invasion.

The cleansing wave of love that send every changeling away...

There are only three ponies who know the truth, Twilight Velvet, Night Light and Twilight herself.

Twilight had reached her peak, she was at the happiest point in her young life. The day of her coronation as Equestria's newest princess had finally arrived. Then the unthinkable happened, Sombra appears in the throne room alive and well demanding his chance to be reformed by pony society. The unthinkable happens again, when his wish is granted, spearheaded by none other than Princess Twilight herself. Will Sombra's nefarious plans bring her to ruin, or will she succeed against all odds? Only time can tell as it reminds them both that plans have a way of changing all on their own.

After being introduced to Dark Magic, Twilight has used it to her advantage multiple times(using it for Zecora's potion, finding the Crystal heart). Twilight starts to experiment with it, causing her to grow obsessed. She's noticed that its beginning to change her. She must stop herself from succumbing to the darkness before her friends loose her forever.

Sombra may have been defeated after his attempt to retake the Crystal Empire, but he was not destroyed. He still lives, and now he seeks to work his way into the mind of Princess Twilight Sparkle. As she struggles with the implications of her new immortality, she finds less comfort in the wise words of Princess Celestia, and is drawn to the dark magic of a fallen king.
