My fairy bottles contain appropriate herbs and minerals, a drop of oil, and a touch of magick to fully empower them as fairy gateways! They can be houses for a specific spirit, or channels for a particular magick.
 
This bottle is an Undine bottle, containing the spirit of a peaceful water spirit. Elemental guardians, Undines guard the Western quarter and are living embodiments of everything Water magick is known for. More information is provided to the keeper.
