Check The Marble Circle (What Else Is There To Do?)

You walk to the center of the room and kneel down on one knee to take a better look at the light yellow marble circle. It is quite large, acting as some kind of dance floor for balls and partys, but not anymore. You place your right hand onto it to feel the smooth marble. It seems to give off a faint heat that warms the skin of your hand as you touch it. The heat then get a hotter and a dim light flashes from somewhere inside the marble, shining through to illuminate the room for but a moment.

You take your hand away from it, but it triggers the marble to react. As you quickly get back to your feet, the marble starts to glow and flash as it turns to a swirling white and yellow, as if it were glass with colored sands shifting and mixing under with pulsating lights. The flashing keeps getting faster until it reaches a continuous bright light. The fog in the room turns light yellow and all around you white figures come to sight. Ghostly souls of men and women, completely naked, except for black metal collars with green hearts on the center around each of their necks, partaking in every conceivable sex act and act of possision with each other possible, almost oblivious to you. They do so on the furniture, floor, and walls, everywhere you look there is at least one spirit savoring themselves. They seem to not be lacking in diversity as there is every kind of race: elves, dwarfs, humans, jiptorus (spider people), orcs, no type is left unaccounted for.

You can hear every one of them moan and smack into each other as they enjoy their spectral orgy of souls. None seem to have noticed you yet, but you do see a few of these spirits on their own, with no partner. You could try and talk to one of these ghosts to understand what is happening or even for the whereabouts of the treasure, but which one should converse with?
