In 28 ABY, Senators Leia Organa and Ransolm Casterfo met at the hanging gardens to discuss matters relating to Rinnrivin Di and his connections to the Amaxine warriors. During their conversation, Casterfo revealed he was a child on Riosa when the Galactic Empire arrived, and under the authority of Darth Vader, commandeered the planet's factories and enslaved its workers, including his parents. In turn, Organa revealed to Casterfo the time she was tortured by Vader for the location of the Rebel Alliance's secret base, and when the Dark Lord forced her to watch her home planet's destruction by the Death Star.
