You decide to not move on quite yet, avoiding the siren song of the doors, and you set to investigating your surroundings more closely.
You find that you are in a stone chamber, though there's something odd about the stone that you can't identify. Something about how it feels to the touch. As your eyes adapt better, you see that there's is a round structure in the middle of the room like a dried fountain, and within it sits a stone cube.
Around the room you find niches in the stone. Within them all lie little trinkets - paintbrushes, pencils, chisels, things of the like. Looking even more you see a table set by the entrance to the hallway leading to the doors. On it lies a notebook, and a pencil.
What do you wish to do?
