Sirrus, during his imprisonment in Spire, built this small craft out of the unusual floating stone that drifts throughout the Age in order to reach the Nearest palace. Doing this was a challenge since Sirrus had to build and maintain special electromagnets out of crystals to bring the Ship to a correct docking altitude and to prevent the Rock Ship from floating higher than the Palace. Several times, the Ship flew away and Sirrus had to start from scratch, but eventually he succeeded.
The design of this craft bears resemblance to an alien starship right from a first glance. When the ship is in its correct position, its 4 small "wings" extend and a stairway extends up to it. To activate the ship, all that is needed is a single switch in the cockpit.
