The IDE team discovers what they believe to be the lost city of the Alicorns and Triax Defence launches an investigation to find the mythical city of Atlantis. With only enough power to make a one way trip, a new team, headed by civilian Cadance, is formed and travels through the Inter-Dimensional Transporter to this unknown dimension. There, they discover the marvels of the city of Atlantis...and encounter a sinister new enemy.
(This story is a retelling of Stargate Atlantis, using My Little Pony characters, and mixed with some Triax Defence characters. While most of it is Stargate Atlantis some of it is my own. Any true Stargate and MLP fan will love this story.)
