21C MYSTERIOUS ISLAND HALL OF PILLARS. Hole 3 drops people about twelve feet into this room, doing 1d6 damage.
Three ghouls, mad with hunger for living flesh, prowl this pillared room.
3 Ghouls (AC 6; MV 9"; HD 2; hp 13, 9, 7; #AT 2 claws, 1 bite; D 1-3/1-3/1-6; SA Paralysis; SD Limited spell immunity; XP 91, 83, 79)
The biggest ghoul wears a gold bracelet worth 210 gold crescents.
A silver holy symbol is nailed above the doorway leading to the Bubble Machine Room and surrounded by potent runes painted with a paste of honey and holy water. The ghouls cannot pass below it. If the holy symbol is taken down, it will prove twice as effective for turning/destroying ghouls and ghasts (double the number affected).
The secret door to the Snake Room is activated by pushing on a stone in the wall.
