Dwelling Trader

While mining underground, it would be fun to break through a wall to find a geode sized room where a trader resides amongst his books and barrels of apples. Book shelf’s above on a catwalk, and barrels and bed below. Selling random items, like the wandering trader, but ones that are related to ores and treasure. He clearly has treasure, perhaps he trades for many pumpkin pies or cakes. :P
