Ransolm Casterfo was a human male politician who served as a member of the Galactic Senate of the New Republic several decades after the Galactic Civil War. Growing up during the last years of the Galactic Empire on the Inner Rim planet of Riosa, Casterfo experienced much hardship and tragedy during his childhood. His parents were conscripted to work on the construction of the first Death Star and later perished due to their harsh working conditions. After a rough childhood, Casterfo was adopted by a wealthy offworld family. Despite his hatred for Darth Vader and Emperor Sheev Palpatine, he admired the Empire's centralization and, in his adult years, collected Imperial artifacts including banners, armor fragments, and helmets.
