...when walking towards the fire to warm yourself, you tripped only momentarily over a small raised section of the floor just in front of the hearth...

...you now find yourself in a dark chamber lit only by the shadows of the hearthfire. Looking around you see only vaguely lit stone wall adorned by only heavy metal rings set securely into the stone. Upon looking more closely at the walls and running your hands over them, you might find a secret passageway. This is where the realm of the hall dead ends into nothingness. Suddenly you feel one of the stones beneath your hand give way as a section of the stonework moves slightly forward revealing a dark doorway.

...perhaps you pause, the chill of the dank dungeon-like chamber becoming too much for you. Turning back to the fire's light, you discover the turntable switch to the hearth area. Activating it, you find yourself transported back to the Hall.
