The Krenim are humanoids from the Delta Quadrant. They are identified by unique features on their temples. They are very distrustful of any outsiders. They do not allow any ships to enter their space.
Their history is a complex timeline. They once dominated a large area of the Delta Quadrant. This happened because they employed ships using chronotron-based weapons. These weapons gave the Krenim a distinct advantage over their enemies. Their ships were always in a state of flux and could therefore pass straight through other ships’ shields.
One Krenim, Annorax, invented a temporal weapon ship. This vessel’s weaponry was capable of removing entire planets and species.
Annorax used the device for over 200 years. He first used it against the Krenim’s greatest enemy, the Rilnar. This resulted in their complete eradication. This caused other problems in the timeline. Within a century, 50 million Krenim had died.
Annorax’s ship was immune to attacks. The crew did not age at all either. Annorax spent his time attempting to restore the Krenim Imperium to its original glory. This didn’t take place, instead thousands of worlds were destroyed. The history was reversed when U.S.S. Voyager captain Kathryn Janway rammed her ship into Annorax’s, destroying his ship and reversing the damage that had been done for over 200 years.The Krenim temporal was designed by Annorax. The weapon had the capability to wipe out entire plants and civilizations.
The first time he used the temporal weapon, millions of Krenim lost their lives. Annorax spent the next 200 years trying to restore the Krenim Imperium.
The sensors on the ship were so powerful, the sensors could track a temporal wave as it traveled throughout the galaxy.
The computers on the ship were quite sophisticated. It allowed Annorax to run simulations to see what effects the temporal incursions would have.
The vessel was almost powerless without its temporal core. Without it, the ship could not remain outside the space-time continuum. The ship was equipped with conventional weapons, transporters, and warp engines. The ship could not travel above Warp 6 due to its size.
