The Sinkhole Geographic Location in D&D Forgotten Realms | World Anvil

The Sinkhole

The stream that flows through The Glitterhame descends through the chasm to an even lower level of caverns—the Sinkhole. Here it joins a subterranean river that traverses dark caverns and forgotten storerooms before connecting with The Black Lake Lake.
