A second, unseen mark on the door briefly flares as Morg pushes on the door, which open inward easily. A split second later a deafening roar erupts from the doorway, and rocks the dwarf backwards. A small wave of water laps at the stone below the bridge in the wake of the deafening sound.
Beyond the door, guttering flames hang unsupported in midair, illuminating a large area in flicking light. A twenty-foot wide moat divides what looks like a shrine into northern and southern halves.
In the northern half, two large stone pillars flank an alter in the form of a plain stone block. A few coins glitter on the alter, visible from the southern doorway. Above and behind the altar looms a huge symbol that matches the one on the stone doors, made from beams of driftwood, fixed in an X-like shape on the wall. A single stone door leads westward from this part of the room.
In the southern half of the room, two ten-foot-wide channels run along the east and west walls of the shrine, spilling out through low culverts tot he south. Two more pillars stand here, and a low stone bridge leads across the dividing channel to the altar and the northern part of the room.
Five lizardfolk brandish javelins and heavy clubs at the cacophonous intrusion, snarling and flicking their tongues towards Morg and the others. At the northern end of the chamber, and shadowed figure looks up from the altar.
As he straightens, he grabs a trident propped up next to him and plants its butt on the stone floor at his feet. In place of hair, the man's head is capped with an uneven covering of white barnacles, clinging to his skin like the side of a ship. Squinting at the far doorway through the relative gloom, he barks out a question.
"Fire cultists! Why should I not kill you?"

The glyph of warding on the door inflicts 23 thunder damage to Morg, unless he can make a Dex save of DC 14 (in which case he takes 11 instead).
