Create a detailed scene depicting the Bene Gesserit sisterhood from the Dune universe. The setting is a dimly lit, ancient chamber with high vaulted ceilings and walls adorned with intricate symbols and tapestries that reflect the sisterhood's long history and secretive nature. In the center of the room, a group of Bene Gesserit sisters stands in a semi-circle, dressed in elegant yet austere robes of deep black and dark gray, their faces partially obscured by hoods. Each sister's expression is calm and composed, their eyes sharp and penetrating, reflecting their intense training in mental and physical discipline. The Reverend Mother, distinguished by a slightly more ornate robe and a commanding presence, stands at the forefront, leading a solemn ritual or discussion. The atmosphere is heavy with the weight of their secretive knowledge and the silent power they wield behind the scenes of the universe's great houses. Soft, ambient light filters through the room, casting long shadows that add to the mysterious and formidable aura of the Bene Gesserit sisterhood
