The Temple of Takshaka is located in the southern third of the abandoned naga city of Vaalki Tanni. It is a huge stone temple built in the shape of a ziggurat. Instead of stairs, it has a series of switchback ramps that lead to the top of the imposing temple.

The interior of the temple is accessed through a sliding stone door at the top tier of the structure. This door was locked until a key, recovered by Blenda Solögon, was inserted into a recessed hemisphere in the center of the door.

The temple was entered for the first time in over 6,000 years by a group of adventuring elves and humans from the surface.

The temple features intricate mosaic tile work, hundreds and hundreds of well-preserved stone tablets and a number of inactive automatons that resemble minotaurs.
