Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

One year after her coronation, Princess Twilight Sparkle is dead, killed by her own subjects out of fear and jealously. After the funeral, Princess Celestia isolated herself from the world, mourning the loss of her brightest student and daughter figure.

But she cannot weep forever. She must take control of her duties once more. Haunted by the memories of the assassination, and its aftermath, Celestia slowly makes her way to Twilight's resting place to find some closure.

"My name is Sunset Shimmer, and there are two Twilight Sparkles who are both madly in love with me.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.
