Derella, a celestial body, existed as part of a star system. It served as the homeworld for Senator Cinderon Malpe, who acted as its representative in the Imperial Senate.
The young-adult novel Leia, Princess of Alderaan, released in 2017 and authored by Claudia Gray, included a reference to Derella. In the initial expert for Leia, Princess of Alderaan, the planet Osk-Trill was identified as the home planet of senator Gall Trayvis, rather than Derella, which appeared later in paperback editions of Lost Stars.
