@Jangel13 (I don't know what happened but I would apologize for the lateness.)
The chieftain dismissed you but not before giving you a shroud. "This is from the drow. It will hide your true form and let you stay unnoticed in the city. The you will be in the ethereal plane but the negative is while in this ethereal state, you will be unable to interact with physical objects. You may pass through walls and non living matter. Thrizel will be your guide to the tunnel then seal it behind you."
Thrizel was one hunched over goblin. Probably from digging his whole life he carried a pickaxe on his back. His rags covered the essentials and his eyes were pitch black. "Me show you the way then me get freedom. You follow me now." As Thrizel turned you saw the bag strapeped to his back. it looked full and heavy. He lead you through a network of tunnels and shafts some needing a rope to navigate. He stopped in the near pitch darkness only lite was the very small torch he held. The goblin pointed at a small hole that you would have to crawl threw on your stomach. "You in then me be free. The end is only a finger left to dig through." As you entered the hole and tried you best not to think about being buried alive you heard some singing from the goblin. "Free me, free me, soon me be free whee." You heard a strange hissing sound. The thought brought your mind to Grizzel. The thought also gripped you with dread as you doubled your speed. Making a fist you punched through the thin pack of dirt just in time to be shot out of the hole like a cannon. In the air you saw the massive city of night. You headed toward a spire of stalagmite intricately carved you impossibly made it threw the window like arch to slide across the floor into a chair. The room was empty.
In the room most of the furniture was carved stone. From the chairs to the bed posts it was chiseled the same way most races carve wood. You would think the amount of detail would render the furniture unable to support and type of stress. This was some ones study. Across the room opposite of the window was the door leading out to your right against the outer wall was a small book case. Although small was filled from top to bottom with volumes containing unreadable markings. In the center of the room was a reading table with a large candle half melted from hours of reading. The table only had one chair. The left wall held a tapestry of fine cloth depicting a symbol you fail to recognize as having any significance. The door was made of low quality iron. Before proceeding you look back out the window to se the smoke from the small hole you were shot out of. It was in the side of the cavern wall almost a hundred feet off the cities floor.
