Scerra Horn was the wife of Jedi Nejaa Halcyon. She was the mother of Valin Halcyon. After the death of her first husband and the rise of the Empire, Scerra married her husband's friend Rostek Horn and had her son's name changed to Valin Horn (nicknamed "Hal"), all in an effort to protect the family from the Jedi Purge. Scerra's grandson—who became a CorSec inspector like his father and a Jedi like his biological grandfather—was Corran Horn.
