Once a year on October 31, witches gather in the mirror world to hold a Sabbath. This is an event where witches exchange experiences and have fun with each other or with other mystical creatures. Witches come in different skin colors, can live for hundreds of years, and know many spells, many of which they come up with themselves. They can be both evil and kind, they can be both grumpy and vulgar. 
The diet of witches is varied and can include both magical fruits and the souls of living beings.
