This story is a sequel to Old Fences
Derpy Doo has left Ponyville behind and returned to her foalhood home at Invitro Hall in Canterlot, serving as a lowly maid to her spiteful aunt, Countess Magnifying Glass. It is not certain how long she will be able to keep those she cares about safe from her family's wrath or how long she will be allowed to keep her precious daughter, Dinky.
Not one to back down so easily, the Doctor plans to let his beloved companion and the mother of his foal return home. He and Derpy's friends arrange for her to attend the Grand Galloping Gala where they may shed light on her torments before the eyes of Princess Celestia herself.
There they will meet old friends and new and try their hardest to find out just how deep their enemy's influence lies and how much danger they may be in.
