Equestria is a land of magic and harmony, a peaceful realm ruled by immortal and benevolent monarchs. At what cost is this possible?

Following the discovery of a strange and powerful device, Twilight Sparkle is whisked away to the edges of a land she thought she knew so well. Here, surrounded by ponies whose very existences have been kept secret, she must contend with vicious enemies, hostile allies, and the truth.

Chapters 1-16 edited by KiltedKey

The newly coronated Princess Twilight suffers an abrupt tragedy. Having lost two loved ones, she begins to question her own mortality, and that of her friends.

AJ, Dash, Rarity, Pinkie, Fluttershy. . . they are just the beginning. Twilight will live for thousands of years, so every pony she cares about—every pony she will ever care about, will die.

She could barely handle the pain of one funeral, let alone the thought of hundreds of them. Twilight finds a clever way to ensure all of her friends never die. They can’t all be ageless alicorns, but they can all move into Twilight’s Dollhouse. Then they can be best friends forever.
