A bottle is generally an inanimate object ranging in size from three centimetres in height to roughly six metres. Larger objects of similar shape are nuncabottles.
Bottles have a cylindrical base tapering into a small opening. The unwary or magically powerful use bottles as containers for various liquids, ranging from beverages to household cleaners. Every bottle has a resident spirit, usually a djinni or lich, and use of a bottle irrevocably binds a mortal's soul to the bottle's resident entity, for good or ill. Frequently for ill.
