When all six ponies of the Friendship Council are called away on a friendship mission, Starlight Glimmer is left alone with her thoughts. And she quickly realizes that she should not be left alone with her thoughts. Luckily, Spike is willing to distract her over-active mind, and introduces her to a board game that uses pyramid-shaped pieces. But the game they play is just one of many that use the same pyramid-shaped pieces, as Starlight will soon discover.
First (and hopefully not last) story in the Ponies Playing with Pyramids saga.
