If Skullport is 120 ft + 3 levels of Undermountain below the Yawning Portal, is it below sea level? Does the Sargauth empty into the sea or into a below-ground reservoir?Skullport is below sea level. The same magical "elevators" that bring ships to/from it & the Seacaves also transfer the river waters to the sea (except what's piped throughout the upper levels of Undermountain, to feed wells in Waterdeep and pumps in Skullport).#Realmslore
