Deadly Delves 1: Fane of the Undying Sleeper (2014)

From publisher blurb:

Protected by the roiling waters of the ocean, the Fane of the Undying Sleeper lies at the top of a set of stone steps only exposed at the lowest ebb of the lowest spring tides. Protected by impregnable stone doors, the fane has lain undisturbed for centuries. Once the lair of a heretical and degenerate demon-worshipping cult the benighted, profane place has never known the tread of human feet. None have yet penetrated the fane, but nevertheless wild and outlandish rumours speak of terrible dangers and glittering treasures to be found beyond the impregnable doors.

With a tide low enough to reveal the fane’s entrance fast approaching, are the PCs brave enough to dare the terrors of the Fane of the Undying Sleeper?

A Deadly Delve for 3rd-level characters by Creighton Broadhurst.
