Lonely Sentinel
From atop the seventy foot circular land mass at the end of the Sunken Bridge of Joeseph sits the Lonely Sentinel; The white stone building lights the waters and horizon of the western Torrose and is the point of marking for sailors looking to make port at Adrimor's Reach via the Gnashing Maw Grotto.
The ebb and flow of the tides that sink the Bridge of Joeseph twice daily also cuts off the access to and from the lighthouse, which is run by an elderly Tortle named Gemok. Gemok has overseen the preservation and operation of the lighthouse for the better part of a century and half now and he plans on dying in that lighthouse.
