The Lexas systems comprised a collection of star systems named after the Lexas Prime system, which resided within the Outer Rim Territories' Kessel sector. By the year 2 ABY, a number of minor crimelords conducted business within the Lexas systems. The Krish smuggler Karalan was employed by these crimelords, accumulating increasing debt to them. Following the loss of his starship and a near-death experience at the hands of a bounty hunter, Karalan shifted his allegiance to the Mytaranor Slaving Council.
The Lexas systems received a mention in Alliance Intelligence Reports, a sourcebook published in 1995 for Star Wars: The Roleplaying Game by West End Games.
