From within the room, you feel mountain grumble around you. It shifts like an old man trying to dislodge wind from his breeches.
While the room stays solid there is the faint sounds of shifting rocks and falling dust, and with a belch a cloud of noxious smoke puffs into the room, coming up from the well at the centre.
You cough slightly at the acrid taste, covering your mouths and crouching low. With the door open the smoke swirls around the roof and begins to drift outwards. As the shuddering rock settles, a morearticleartificial beat is heard. A repitive thumping, faint and far off, but humming through the air of the mountain. There is a faint drone that may even be chanting, but you cannot tell for sure.
