For generations, the Royal Sisters have ruled side by side.

They watched as empires rose and fell. Those they have called friends have grown and passed right before their very eyes.

But one thing has remained constant in their lives....eachother.

Their love for one another never wavered in the time they lived, growing stronger by the day. The love they share now would shock their ponies. They would call it "immoral", "illegal", "disgusting".

That's why the Royal Sister's would take this secret to their graves.

Nopony must ever know that Princess Celestia and Princess Luna have more than a familial love for eachother.
