Dark Sun: The Scorched World of Athas
Ziggurat of Kalak
“The great Ziggurat towered above the squalor of the sun-baked city. Each level of the terraced pyramid was finished in glazed brick of a different color: gleaming violet that the base, then indigo, azure, green, yellow, fiery orange, and finally scarlet.” -A chronicler of Athas
The Ziggurat was sealed following the death of Kalak so that no one could enter and retrieve the dangerous and powerful artifacts that may remain. Rumor persisted of a few souls that were able to break in but were never heard from again.
During the True attack on Tyr, several groups were able to enter the Ziggurat and a series of tunnels connecting it to the Golden Tower was discovered. The Veiled Alliance has attempted to seal the structure once again.
