Bessa is the wife of Gan and as his wife she is seen as the only deity with enough power to influence a person's life. Thus, she became the patroness of gamblers. Additionally she is the patroness of riddling contests, since she is said to have invented the game to entertain her husband.
She is the goddess of "khef", life force; her symbol being the rose.
She has diverse worshippers, from people about to take court cases, to those about to undergo surgery and those who are about to take a difficult journey. They all make offerings to her before strarting their trials. If they have a successful outcome they make further offerings to her to insure her future kindness. Doctors and nurses are protected by her, with many healers wearing the rose for luck and strength.
