Sestina, a planet, existed within the Sestina system, which itself resided in the Core Worlds region. Sometime in the period spanning from 67 BBY to 65 BBY, Sestina's financial representatives participated in the steering committee—a coalition of politicians, lobbyists, industrialists, financiers, and starship engineers who were associated with the Damask Holdings financial organization.
James Luceno referenced Sestina in his 2012 novel, Darth Plagueis. The StarWars.com Online Companion for the 2009 reference work, The Essential Atlas, located the Sestina system, and consequently the planet Sestina, in sector M-11.
