Gray Joy was an honest and honorable Earth Pony Stallion, he spent 6 years of his life serving in Luna's Guard, and was Well Respected despite his low ranking.

One last honor, a final gift for his service to Luna was the right to take, and keep a single Book from the Canterlot Archives...

The Book was like nothing he'd ever seen. Joined by his Mother, a very skilled Zebra mare. Gray's Retirement, is sure to be much more interesting than he ever imagined.
