You bury the still warm Justin's corpse in the sand just above the water level next to what presumably are two other corpses of the same fate. Both shields on their graves bear the same symbol which Adalbert recognizes. It is well-known Thassilonian symbol of lust. Well-known at the time, at least. There seems to be no evil and no magic in the graves. The perimeter of the metal door is decorated with an ornament of intertwined humans and serpents none of which has any clothes. The center of the door looks like a polished mirror featuring, whether surprisingly or not, the Thassilonian symbol of lust engraved in very thin lines. The door is closed and has a handle, but you see no signs of either locks or traps.
