"Hidden Cult" refers to a mysterious, often underground group with exclusive beliefs, rituals, or agendas that aren't widely understood or accepted by mainstream society. These groups typically operate in secrecy, sharing coded knowledge or symbols among dedicated members. Hidden cults are often driven by unconventional ideologies, practices, or pursuits, which create a sense of allure and exclusivity. The mystique around them can lead to fascination, speculation, and sometimes fear from the outside world.
