Crullov was a place of interest found on the planet of Corulag, situated within the Core Worlds. It was in the city of Curamelle on Corulag that Chass na Chadic, a former New Republic pilot, lived eleven months following the Battle of Jakku, a decisive final victory for the New Republic over the Galactic Empire occurring in 5 ABY. She later relocated to Crullov due to lower rent costs, as her New Republic pension was approaching its end. Soon after, Chadic realized her new, closet-sized apartment in a building teeming with death stick users would not provide her with a full night's sleep.
Within current Star Wars canon, the 2021 novel Victory's Price, which concludes Alexander Freed's Star Wars: Alphabet Squadron trilogy, contains a reference to Crullov. In the Star Wars Legends timeline, Crullov City initially appeared in Coruscant and the Core Worlds, a resource book for the Star Wars Roleplaying Game that Wizards of the Coast released in 2003.
