"The Great and Powe-*hack* Powerful Trixie's revenge will not be stopped by a mere layer of dust, even if it is half a ponyheight *sneeze* thick!" Trixie half-whined, the cool blue glow of her horn lighting the ancient, unmarked walls of the maze that drilled it's way miles deep into the mountains under Canterlot. When she found hints of great magical power buried in the depths, Trixie hadn't expected a maze.

Even then, one needed to be a cunning pony to find whatever was hiding at its very center.
