Kavan, a world situated within the Hapes Cluster, was characterized by its intricate network of tunnels. These tunnels served as crucial shelters for the native Kavani people, offering refuge during the planet's severe winter seasons. It was on this very planet that Jacen Solo, recently crowned as the Sith Lord, committed the act of murdering his aunt, Mara Jade Skywalker, in what he considered a sacrificial act. Initially, Jacen had intended to sacrifice his own parents, Leia Organa Solo and Han Solo, followed by his Hapan partner, Tenel Ka Djo, and their shared daughter, Allana. However, his inability to locate his parents, coupled with his growing affection for Tenel Ka and, more significantly, Allana, led him to reconsider. Consequently, he chose Mara as his sacrifice, engaging her in a prolonged fight that resulted in extensive damage to the tunnels' interior. Ultimately, he ended her life with a poisonous dart, leaving the scene only to return and discover Mara's son, Ben, his cousin, holding his deceased mother.
Three months following his mother's assassination, Ben Skywalker, accompanied by Captain Lon Shevu, revisited Kavan. Their mission was to meticulously investigate the crime scene, seeking any evidence that would conclusively implicate Jacen in the murder. During this investigation, Mara manifested before Ben as a Force ghost, subtly pulling strands of her own hair. This action conveyed to Ben the importance of hair as evidence; finding her hair on something belonging to Jacen would expose the truth. As his mother began to fade away, Ben expressed his love, whispering "I love you, Ben." before vanishing.
