Humbarine was a Core World founded at the beginning of the Republic. It was one of the core writers of the Constitution of the Galaxy. Later on, it was molten to slag during the Clone Wars by General Grievous and the Invisible Hand.
Humbarine was also home to one of the galaxy’s oldest working atom clocks, which was located in the Humbarine Grand Capital Building. The clock, which had only one other surviving twin on Coruscant (two others existed on the planets Duro and Corellia, but broke down and were never restored), was worth its weight in gold to anyone who could reclaim it.
About 12 ABY it was recovered by a little-known smuggler named Regs Tii from the molten slag of the Grand Capital Building, where it had survived, somehow, intact. Tii later gave it to the New Republic Senate, where it was hung in the Coruscanti Senatorial Hall.
