The Lance family are prominent residents of Star City. Captain Quentin Lance is a long-serving member of the SCPD; his ex-wife Dinah is a professor of Greek and medieval history at Central City University. Their oldest daughter, Dinah Laurel, works with the DA's office. Both of their daughters, Laurel and Sara, had romantic relationships with Oliver Queen; Sara joined Oliver on his ill-fated sea cruise, stealing him back from her sister, and was assumed dead when the ship sank. In reality, she was rescued by Dr. Anthony Ivo, who recruited and trained her to aid in his search for Mirakuru. She met Oliver again during his time on Lian Yu, turning against Ivo, and was later taken in by Nyssa al Ghul, becoming a member of the League of Assassins and Nyssa's lover.
Believing their younger daughter to be dead, Quentin threw himself into his work as a police detective and became an alcoholic, and Dinah left him and moved out of the city. Quentin has had a long history with Team Arrow, initially trying to take down The Hood, then working with them against Malcolm Merlyn. When Sara returned, becoming the vigilante known as "The Canary", Quentin was for a long time the only one who knew she was alive, though Dinah and Laurel eventually found out. Sara rekindled her relationship with Oliver, leading to further tension with Laurel, but eventually left him and Starling City. She secretly returned without her father's knowledge to hunt down Merlyn but was killed by Thea Queen acting under Merlyn's control. Laurel, who knew of her sister's secret identity, became the Black Canary to honour her memory.
Oliver and Laurel did not tell Quentin about Sara's death, and when he found out this severely damaged his relationship with both his daughter and the Arrow. A year after Sara's death, Laurel found out about the Lazarus Pit and took Sara's body to Nanda Parbat, where Malcolm resurrected her at Laurel's request. Initially, she was barely herself, possessed by uncontrollable bloodlust, but after her soul was restored by John Constantine she left Star City once more to find a way to become whole again.
