A treasure vault complex was constructed on the planet Dellalt by the Tionese empire of the tyrant Xim. The vaults' facade bore an inscription proclaiming them as a tribute to Xim, intended to safeguard the wealth he was anticipated to gather from his war with the Hutt species. Nevertheless, the Third Battle on Vontor resulted in the despot's downfall, leaving the vaults perpetually empty. Millennia later, the historian Bleys Harand journeyed to the vaults, seeking an authentic portrayal of Xim. He failed to find such a representation, either within the complex or during his travels, a narrative chronicled in his book Travels Amid Strange Stars.
Eventually, the treasure belonging to the despot Xim was discovered within these vaults by Han Solo and Chewbacca in 1 BBY.
