Human: Generate for me a description of a mystical hallway with a black marble floor, a dark red carpet, a door, and a plant. Assistant: 
This large hallway is slightly curved and has a rather high ceiling, well lit with pale blue oil lanterns mounted on the wall. A dark red carpet runs down the center of the hallway, covering a rich black marble floor shot through with gold veins. A small plant in a vase the same color as the carpet has been tucked into the corner, opposite the door leading back to the streets of Shard.
