In 0 ABY, the Rebellion and Galactic Empire skirmished in the Krant system. It was one of the first events of the Krantian Civil War.
Early in the Galactic Civil War, Krant became a major rendezvous point for Bothan spies and Rebels. In 1 BBY, Bothan spy Utric Sandov arranged a meeting with Princess Leia to discuss information that could be vital to the Rebel Alliance.
While Leia Organa was moving to Krant, her ship, the Cretacian, came in contact with and fought TIE/LN starfighters. One of the starfighters damaged the Cretacian and caused it to crash on the planet. Only Organa, the protocol droid C-3PO, and some Rebel troopers survived the crash.
On Krant, Leia Organa was ambushed by stormtroopers, but she was rescued by the Jedi Echuu Shen-Jon. She later met Utric Sandov, who revealed to her that the Empire had found the Vor'Na'Tu.
