According to surviving accounts dating back to -3923 AR, the kings of Ninshabur sited their treasure vault here "at the center of a plaza of cracked stone". Four six-mile-long boulevards lead to it, lined with numerous statues of sitting creatures such as the shedu, sphinx, gorgon, and lamassu.
The accounts note that Tabsagal "became the last refuge of Ninshabur's nobles" three full moons after the Tarrasque attacked. By then they had "shrouded" the whole city in magic and sealed the treasure-vaults thrice. The nobles also ordered their men to kill any refugees seen traveling toward the complex. This apparently worked against the monster, but "the ruling caste eventually succumbed to hunger, disease, and suicide". None mourned them, and until recent expeditions, the very knowledge of these nobles was forgotten.
