Perhaps the most important place for the Assassins' use, the basement has further shelves and cabinets, as well as a large work table. The shelving was supposedly for backstock and storage, but there's little of it there. The cabinets and filing intended for monitoring paperwork, profits, and recipes are half empty. Scattered papers litter the floor.

The table holds several bowls, mortars and pestiles, and a strange set up of tubes and glass that would apparently be some kind of distillery at a guess.
