The Moondeep Sea was a subterranean lake approximately 240 miles (386 km) wide found in the Underdark beneath the Galena Mountains.[1]


The cavern which contained it was known as the Vault of Gnashing Teeth, so named for the countless animated skulls stuck to the cavern's ceiling.[1]

The Moondeep Sea was known for its giant aquatic spiders and the city of V'elddrinnsshar‎, which lay on a mile-wide island dominated by a plateau in the middle of the lake.[1]
