The Kaldani Spires Residential Apartments stood high above Coruscant's Monument Plaza as a prestigious and sought-after apartment complex. Hego Damask, a Mygeetan Muun financier and secretly a Sith Lord, possessed this building, and he kept his own private residence at the very top.
Built using the architectural principles of the Hasennan Period, the building represented luxury. Although not as imposing as 500 Republica, it was the most coveted address in Galactic City outside of the Senate District near the end of the Old Republic. Hath Monchar possessed a suite on the 500th floor when he died in 32 BBY. It was within the Kaldani Spires penthouse that Darth Sidious used Force lightning to murder his Sith master, Darth Plagueis.
