The Montalvia municipal prison existed on the Inner Rim world of Kyrouac in the time of the Galactic Civil War.
The Montalvia city jail first appeared in Alone Against the Empire. This was a solo RPG adventure penned by Lester W. Smith for use with Star Wars: The Roleplaying Game from West End Games, and it was published within Challenge 32 during the year 1988. Due to the adventure's release outside the Lucas Licensing procedure, its status of canon in the Star Wars Legends storyline was never verified.
