After an unknown accident Twilight Sparkle and Rainbow Dash awake to find themselves sharing the same body! Now they must struggle to hold themselves together as their world is turned upside down. How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.

This story is a sequel to Veil of Thoughts

After surviving a spell that merged Twilight and Dash into a single being during the story Veil of Thoughts, the two mares are still struggling to get back to as normal a life as they can have. Except, didn’t they used to have more friends? Why is it so hard to remember…

The boundaries of reality are starting to crumble apart. Half dreams haunt their waking world. Memories of another life seep through their mind. What they were is quickly becoming little more than Fragments of Memories.

Friends, family and even enemies will come together to save Twilight Dash before it’s too late and there is nothing left to save.

The long awaited, highly anticipated, sequel to Veil of Thoughts. Don't forget to remember.

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.
