Turco Prime, a celestial body, existed where the Mid Rim Territories and the Slice met. It was positioned in grid square Q-8 of the Standard Galactic Grid. By the time of the Galactic Civil War, a Galactic Empire shipyard was established there, which faced the New Republic. In 5 ABY, the New Republic engaged in combat to seize the shipyard. Fleet Admiral Gallius Rax referenced this struggle for control, along with other Imperial sites like Turco Prime, during a discussion with the newly formed Imperial Shadow Council that year.
The planet Turco Prime initially appeared in Aftermath: Life Debt, a 2016 novel and the second installment in Chuck Wendig's Star Wars: The Aftermath Trilogy.
