Located on the Core Worlds planet Chandrila, the Silver Sea was an expanse of calm, slate-gray water. Chandrila's capital, Hanna City, was located near the sea, as was Landing Platform OB-99. The office of New Republic general Leia Organa overlooked the sea, as did her apartment's balcony and a tavern. Part of the Silver Sea's coast was formed by cliffs against which waves crashed. There were also docks located in the sea.
Hanna City was located along the coast of the Silver Sea.
Four years after the Battle of Yavin, former smuggler Han Solo traveled to Chandrila aboard his starship Millennium Falcon. Solo flew the Falcon over the Silver Sea, which sparkled beneath the craft.
A year later, in 5 ABY, Chandrila's transition from the winter to spring seasons resulted in the formation of storm clouds over the sea that released rain and lightning. By that time, New Republic pilot Wedge Antilles allowed Temmin Wexley, son of fellow New Republic pilot Norra Wexley, to perform training exercises in an X-wing starfighter above the Silver Sea. When Temmin boarded the starship Halo to meet with his mother and her crew, the sun rose over the Silver Sea. Later, Antilles had Temmin fly over the sea in a flight simulator. In the simulator, Temmin repeatedly crashed his starfighter, including an instance where he flew close to the sea's surface to avoid sensor arrays.
Stones from the Silver Sea were brought aboard the Halcyon and stored in the Climate Simulator
A tavern that was located above the Silver Sea was frequented by Imperial defector Sinjir Rath Velus near the end of the Galactic Civil War between the Galactic Empire and the New Republic. After the Battle of Jakku in 5 ABY, which ended the conflict, Velus and several of his friends visited the tavern. During their visit, Chandrila's moon brightened the sea. At the end of their night, Velus and his last remaining companion, bounty hunter Jas Emari, stood and spoke outside the tavern as wind blew off the Silver Sea and waves crashed below them.
An alcoholic drink called the Silver Sea Martini was served aboard Chandrila Star Line's MPO-1400 Purgill-class star cruiser Halcyon in 34 ABY. Like the sea, the drink was gray in color. The Halcyon also contained a courtyard known as the Climate Simulator, which contained stones collected from the Silver Sea.
The Silver Sea first appeared in the current Star Wars canon in Chuck Wendig's 2016 novel, Aftermath: Life Debt, the second book of the Aftermath Trilogy. The Silver Sea was first introduced to the Star Wars Legends continuity in the 1998 reference book The Essential Guide to Planets and Moons by Daniel Wallace, and made its first full appearance in Greg Keyes's 2001 novel The New Jedi Order: Edge of Victory II: Rebirth, the second book in the Edge of Victory Duology and ninth overall in the Star Wars: The New Jedi Order series.
