Human: Produce a detailed written description of a chilling scene inside a mansion with a plaque and chairs. Assistant: 
Twelve chairs surround a high table in the center of this rounded chamber, and a shining gold plaque with an inscription repeated in half as many languages hangs on the far wall. Beyond that there is nothing here, save a near-tangible stillness and a low, powerful thrumming just barely at the edges of hearing. A section of the wall shows signs of recent repairs and construction centered about a heavily reinforced passageway.
