Deep in the Canterlot Archives sits a small, unassuming black pyramid-shaped artifact. Left alone, it has been collecting dust for centuries. But one day, the princess's own apprentice Twilight Sparkle happens across it. She is briefly interested, but is then distracted by finding her actual quarry... Until she hears a voice in her head.
"Hello...? Is anypony out there? Anyone? Please... It's been so long... I'm so alone..."
"What? Who are you?"
