A Rock For Hard Times

Cloudsdale sent sheets of rain to Ponyville today, a downpour to make up for the dry spell we'd had for the harvest. Now that the clouds have cleared, everything looks so clean and fresh. I hadn't noticed the dust before the rain washed it away, but the dry soil had started to blow around and the short grass in the pastures wasn't holding it back. I gathered my books near the door to the balcony where I could hear the waves of rain wash across the stones and smell the mist and spray. Starlight Glimmer retired to the silence and isolation of the library.

Starlight Glimmer told me something odd today. She told me that Maud had mentioned that with the right rock you could rule all of Equestria. Maud may have been jesting, it's hard to say with her, but then she may have been serious. I've seen a few magic-channeling rocks here in Equestria, such as the one that used to be in the heart of the Changeling Hive, so "the right rock", for the right kind of magic, is not far fetched. What dangers would such a rock entail? If I got that desperate, would I dare look for this rock? Could it be tuned to the Magic of Friendship? If Maud knows this, there could already be ponies out looking for such a stone.
