Grid 19 was a portion of the Southern Underground located within the bounds of the Imperial City. The Soft Heart Cantina was located within it.
The block where the cantina was situated was destroyed by fire in the year 1 BBY. The official explanation was that the well-known criminal Varlo Brim committed arson. However, a conspiracy was suspected to be behind the fire because, in a highly improbable coincidence, Brim was discovered deceased from "natural causes" in his living quarters almost immediately after the incident. Additionally, the fire-suppression systems, inspected just two months prior, malfunctioned. Finally, the droid firefighting teams were misdirected, resulting in a delayed arrival that prevented them from extinguishing the flames in time.
