The Kal'ki'jaakt (Unbeatable) was an advanced battleship and the premier warship of the Rim Empire, an ancient technologically advanced empire which ruled the Galactic Rim section of the N'Akkiarl Galaxy c. 5,000,000 BBY. The Kal'ki'jaakt was to be the first of a class of super-battleships. For unknown reasons the battleship project was cancelled and the Kal'ki'jaakt saw very little service, only an early prototype was seen by the public then both the prototype and the Kal'ki'jaakt were hidden under an ice field on the planet Huukeltelax.
