Grid 19 was a section of the Southern Underground in Imperial City. It contained the Soft Heart Cantina.
Fire
The block containing the cantina burned down in 1 BBY, officially attributed to arson by the known criminal Varlo Brim. There was some suspicion of a conspiracy regarding the fire as Brim was found dead of "natural causes" in his cube almost immediately afterward in an unlikely coincidence. Furthermore, the fire-suppression sprayers, which had been inspected two months before the fire, failed to work; and finally, the droid fire crews were misdirected to the wrong location so that by the time they arrived it was too late.
