Qasmudha (building)
The Gilded Palace was once the estate of the Ritualist warlord Uzaq Dham. Uzaq, his followers, and the city around Qasmudha were all devoured by the great Worldeater in the 3rd century, but the Qasmudha miraculously survived. The great palace has since been rebuilt and expanded thousands of times since, and is considered one of the great wonders of Sarradon.
Many great empires have been ruled from Qasmudha, coincidentally the Udayyirs, the family that slew the Worldeater.
