Lakarian City was a major city on Cardassia Prime. Its leisure facilities included an amusement center – one to which Gul Dukat had been planning to take his son, Mekor, for his eleventh birthday in 2371. (DS9: "Defiant")
In 2375, following the Cardassian Liberation Front's sabotage of the planet's power systems, which caused a planet-wide blackout, the city was leveled by Jem'Hadar troops, on the order of the Founder in command on the planet. All two million inhabitants were killed "in a matter of seconds". This action provoked the defection of the Cardassian military, and a planetary revolt, ultimately turning the tide of the Battle of Cardassia.
