A star system mentioned in The Next Generation as a Pakled trading post and the scene in 2380 of the Pakled ambush that destroyed the USS Solvang.
The Kalla system is first named in the Next Generation episode Firstborn, in which the Enterprise-D learns that the Duras sisters sold stolen magnesite ore to a Pakled trader at Kalla III.
Lower Decks returns to it in the first-season finale No Small Parts. The California-class USS Solvang answers a call there and is seized by a patchwork Pakled vessel many times stronger than Starfleet expects. Its captain orders a jump to warp while still held by a grappler, and the ship is torn apart.
The Cerritos comes to investigate and falls into the same trap. Pakled boarders begin cutting up the ship for parts, Shaxs is lost carrying a computer virus to the enemy vessel, and only the arrival of Captain Riker's USS Titan drives off three more Pakled ships.
