The basement of Saltgrjot Moss & Mortar is a compact underground alchemical workspace packed with jars, plants, storage and a central worktable. Stone walls enclose the room tightly, while shelving and supplies leave little unused floor space. A square structural opening or shaft breaks the center of the layout and helps distinguish the cellar from an ordinary storage room.

For a GM, the basement is ideal for secretive work, ingredient storage or discoveries beneath an otherwise respectable shop. Bottles and shelves provide environmental clutter, the narrow room keeps confrontation close and the central opening can serve as a practical architectural feature, hazard or access point depending on the scenario. Paired with the ground floor, it gives Moss & Mortar a believable hidden working level where the more volatile side of the business can stay out of customer view.
