The Roost functioned as a base of operations for a group of mercenaries under the leadership of Ranzar Malk, and it was a space station. Din Djarin, the Mandalorian bounty hunter, made a stop at the station to become part of a team of mercenaries. Malk had given them the assignment of rescuing Qin, a prisoner, from the Bothan-5, which was a New Republic Correctional Transport. Djarin was betrayed by the team, who left him to die; however, he managed to escape, returning to the station with Qin, who was unknowingly carrying a tracker from the prison ship. After paying Djarin and allowing him to depart, Malk gave the order for a gunship to take him down. But the distress signal from the tracker alerted a New Republic X-wing squadron, who upon detecting the gunship, attacked the station and destroyed it.
The sixth episode of The Mandalorian, a television series created by Jon Favreau in 2019, was the first time the Roost was shown. The space station's design was inspired by real-world automotive chop shops, which feature greasy, spark-filled garages where workers assemble and disassemble motorcycles and hotrods, in contrast to the more organized Imperial or makeshift Rebel hangars typically found in Star Wars. Ryan Church, the concept supervisor, intentionally modeled the space station's exterior after Cloud City, but with a more crude interpretation. Church opted for a trapezoidal design for the chop shop's aperture to space, consciously moving away from the parallel lines seen in First Order or Imperial hangars.
