You two make your way through the palace, then out to a flattish area behind it. Turns out the guard had been much larger before Luna’s return. Made sense, when you thought about this reclusive tribe she’d brought back into the ponykind fold with her return, all of whom seemed to be devoted to her. The royal guard had shrunk by a third. Luna’s devotees, however, had claimed a cave system inside the mountain the palace is built near. These had apparently been their domain before her banishment, and they were more than happy to take the place up again. This had left several of the guard’s buildings dormant, and while many were torn down for materials to use for later maintenance on the rest, a couple had remained, now overgrown and forgotten.
