As you descend down one of the spiral staircases of Brǎgon Castle, the air cools, and becomes stale. You mine further and further into the depths of the earth, eventually emerging through a stone archway into a massive underground hall, as big as a city. It is lit by huge fires in each corner, and is epically tall, the roof far out of sight. Within the huge expanse are a number of shops, houses, taverns and other city buildings.
