As you approach the statues one begins to shudder and emits a dire groan which pierces your very heart with dread!! This is the 'Groan Of Stone', a dreadful song which haunts the breasts of all who have heard it... This groan is produced by the tremendous internal pressures of an air-filled respiratory system which has been Gorgonized, and may precede the violent explosion of the statue in question. Regardless, all who have heard it are assumed to be Cursed [roll d20 to determine potency of curse]
