Four thousand years ago, the privileged sons and daughters of the Tetan royalty began experimenting with the Dark Side of the Force, introduced to them by the royal heirs Satal Keto and Aleema. They formed a group known as the Krath, which used Sith magic and military force to quickly conquer the system. Public executions of rebellious carbonite miners were held in the central plaza of the ruling Tetan city of Cinnagar. The Krath took up residence in Cinnagar's iron citadel, which contains an inner city and an opulent palace behind its walls. Beneath the citadel are underground dungeons and a vast cavern, where the Krath hung political prisoners. The Jedi knight Ulic Qel-Droma, following a Tetan attack on a Deneban Jedi assembly, traveled to Cinnagar in order to learn the Krath's Dark Side secrets. In the ensuing months Satal Keto was killed and a Jedi attack force attempted to rescue Qel-Droma from the iron citadel, but he had succumbed to the Dark Side and insisted on remaining in Cinnagar. Qel-Droma joined forces with the Sith Lord Exar Kun, and the two implemented their plans to bring about a new Golden Age of the Sith. Six months later, with the Krath armies conquering nearby systems, the warlord Mandalore chose to strike at the heart of the overextended Tetan empire. Ulic Qel-Droma defeated Mandalore in single combat, and won the warlord's loyalty and the use of his deadly armies. Later, Aleema attempted to reassert her power over the Krath forces by abandoning Qel-Droma during an attack on Coruscant, but he was rescued and eventually had Aleema killed.
