Thuk slays the pirate outright, ripping his back open with the falchion. The heroes take a moment to look around the roughly 30 foot by 30 foot room.
The regular, masonry walls of the tower gave way to natural stone walls. In this roughly rectangular room you face a series of natural stairs to the north, and a closed door to the right. The air is different here, fresh with the tang of salt. From somewhere in the distance comes the thrumming roar of the surf.
The walls are decorated with carvings depicting some sort of evolving dragon. On the floor, before the portal you entered, a sigil is carved into the stone.
