Ss'thar'tiss'ssun

The sarrukh, the yuan-ti progenitor race, built this temple-city thirty thousand years ago, making it one of the oldest ruins in all Faerûn. Ss’thar’tiss’ssun was abandoned after the death of the deity it was built to exalt. It stood sealed for thousands of years until it was restored by the ancient naga Terpenzi and its followers, marking Najara’s first flowering. However, in the Year of the Moor Birds (90 DR), the Shadowking and other Netherese wizards slew Terpenzi and partially razed the city.

Humans briefly inhabited the land above the ruins, but their habitation, called Serpent’s Cowl, now stands empty. The surface dwellers were annihilated when the Netherese wards designed to keep out serpent kin failed roughly a hundred years ago. The Shrine of the Cowled Serpents lies in the heart of ruined Ss’thar’tiss’ssun. Over the last century, yuan-ti have uncovered the shrine and often visit the location. It is inhabited by all manner of monsters and treasures dating back to the original Kingdom of Snakes.
