Ziilakgurat

From publisher blurb:

In the eastern part of old Ardust, a square, 40 foot tall, gleaming white ziggurat rises above the shattered ruins. At the top of the ziggurat a dragon’s head faces the rising run, toothy stone jaws open wide. Within the jaws of the white dragon, a vertical shaft descends into blackness.

This is Ziilakgurat (“Falcon’s Wisdom” in Draconic), the sacred abode of Hafti criotaurinx and Keeper of Secrets. Prophet Shrick, a rat folk oracle, seeks to bind the ancient spirit and steal her power. His minions imprisoned Ziilakgurat’s porcelain defenders within a funerary chamber, taking severe losses doing so.
