The stairs are a tight fit for Beruga, or would be if she truly was as massive as her fur made her look. Still she blots out most of the light until clear of the stairwell. The light light there is down there reveals a single large room. Sections of the floor are brighter than others and you realize there is a large section of the room filled with a black and white jumble of square block floor paving stones about 2 feet square. Other than that all you find area a few scraps of old boxes and rusty bits of metal along with the occasional weed, dead vine, or rodent skull. Sniffing around you catch the scent of several small animals that come and go from the room but nothing else.
As you move around in your search through the near pitch blackness, trusting your nose to alert you to anything of interest you feel a slight tingle in the air that you know indicates magic is near. Carefully sensing about you realize the magical emanations are coming from the black and white section of the floor. Suddenly a dim light pierces the blackness, momentarily blinding you. Crouching in a defensive position you shield your eyes and sniff. Dirt, stone, bits of nature, old wood, rusty metal, small critters, and that is it. A creaking noise sounds and the focus of the light shifts as it dims allowing you to vaguely make you a small supine figure in one corner.

The figure is a mix of metal and fur with the light emanating from one of its eyes leading you to suppose it is some kind of golem? A soft feeble voice comes haltingly from the figure
