Human: Produce a detailed written description of a magical scene inside a shop with shelves, corked potions, wands, and a door. Assistant: 
A thin haze of yellow smoke drifts lazily through the shop, originating from a crack in the back wall next to a closed door with a sign that reads, \"Backroom.\" Shelves line the other walls, each one occupied with a number of corked potions, categorized piles of wands and other trinkets.
