Le'Roche was an island located on the planet of Krant. Following the Imperial Strike Force Alpha's capture of the Rebel Alliance's Ghost Base between 0.5 ABY and 2 ABY, Bothan spy Utric Sandov and members of the Krantian Resistance sought refuge on this island. The survivors proceeded to establish a new base on Le'Roche, which included a Command center, prefab shelters, a troop center, a War Center, and a water-based shipyard. R2-D5 labor droids were responsible for gathering the necessary resources for the base's operation. Once the Rebel army, under the leadership of emissary Leia Organa and the exiled Jedi Echuu Shen-Jon, successfully liberated Ghost Base, the Krantian Leader dispatched two transports to bring Organa to Le'Roche for a meeting with Sandov. Sandov then revealed to them that the Empire had acquired a Jedi artifact known as the Vor'Na'Tu, prompting Organa and Shen-Jon to leave Krant to recover it.
The first mention of Le'Roche appeared in the strategy guide associated with the video game Star Wars: Galactic Battlegrounds, which was released in 2001. The island's existence was revealed during the second mission of the Princess Leia campaign.
