The Azure Nebula is a type 11 nebula, the home of the Iccobar and location of the Holocovia system, found on the border between the Federation and the Klingon Empire. The USS Excelsior entered the nebula in 2293 during Captain Hikaru Sulu's ill-fated rescue of James T. Kirk. There he encountered a Klingon battle cruiser commanded by Captain Kang, who attempted to escort Sulu out of the nebula, but was disabled when the Excelsior ignited the nebula's sirillium gas.
