Sarnath is a huge Aboleth city, located in the Underdark.

The city of Sarnath is vast, and is home to thousands of these strange aquatic creatures. The City is known for the hundreds of tall black obelisks that dot its landscape, each imbued with powerful Aboleth glyphs and runes.

Sarnath is unlike other Aboleth cities in that it was not built on the world of Oris; instead, the city was magically transported from the world of Charos; the orginal home of the Aboleth.
