Sentinel Island stands as a testament to lost heroism and maritime mystery, rising defiantly from the tumultuous Ravaged Sea, 50 miles south of Seregon. Dominated by the monumental busts of the Sentinels of Seregon carved into its cliffs, this island once thrived as a bastion for sailors, soldiers, and adventurers. Now abandoned, its castle and village lie in ruin, sealed and warded by the ancient wizard Ambergris.
Beneath the island, hidden in an abandoned cave complex accessible only by navigating treacherous waters, lies The Chamber of the Marshal. This secret room, veiled by natural rock and forgotten time, was chosen by Captain Marrowtide—formerly Maarten van der Zee—as the final hiding place for his grand fortune. The treasure chest, containing over 5,000 gp in coin and gemstones, symbolizes Marrowtide’s ambition to retire after his “big score” on Elephant Island.
The captain left a map of the cave entrance to guide treasure seekers, showing how to navigate a small boat into the cavern. Once inside, adventurers must contend with remnants of the island’s history and the encroaching influence of the Ravaged Sea Corsairs, who now use the caves as a base.
Rumors swirl about the shifting mountains of Sentinel Island, with whispers of a fifth, faceless bust emerging from the cliffs, suggesting the island may still hold untold secrets. Marrowtide’s treasure, and the dangers that surround it, are both a lure and a warning to those bold enough to seek fortune amidst the ruins of history.
