Kyana Prime

Kyana Prime was the first planet in the Kyana star system of the Alsuran sector, and the site of a major Krenim colony. 

Geography
Kyana Prime was marked by its isolated, light brown continents and vast blue oceans. At least one settlement was situated on a river. 

History
The Krenim colonized Kyana Prime at some point before 2174. By the mid-22nd century, the colony was the home of the military temporal scientist Annorax and his wife. The Krenim Imperium was at its height at the time but suffered from a war with the Rilnar. Annorax worked on the development of the Krenim temporal weapon ship during his time on Kyana Prime. 

During the genocide of the Krenim people at the hands of the Vaadwaur Supremacy in 2410, the Kyanans used Annorax's specifications to remove Kyana Prime from normal space-time. The temporal generators were operated from Prime's sole natural satellite, Kyana Moon. The planet's existence and the survival of the Krenim species were a secret well kept from the Iconians and their servitor races, the Heralds and Vaadwaur. The Kyanans made a deal with the Alpha Quadrant Alliance to develop the Krenim temporal weapon ship and use it against the Iconians. 

Alternate timelines
In an alternate timeline where Annorax built his weapon ship in the 22nd century and used it to defeat the Imperium's enemies. These temporal incursions prevented the existence of the Kyana colony, and Annorax's wife. He named his ship the KYANA PRIME undefined and attempted to restore the Krenim's former might and his colony. In 2374, history was restored when the Federation starship rammed the Kyana Prime, causing a temporal incursion that erased the ship and its actions.
