Sian Sibley is a writer, witchcraft practitioner, and ecologist from Wales, with over thirty years of experience in plant spirit magic. She holds master's degrees in Biological Science and Ecology and Spirituality, blending scientific insight with esoteric wisdom. As the leader of the DragonOak Coven for twenty seven years, she has guided practitioners in structured, nature-based spiritual practices that honour both tradition and personal growth.

Her books, Unveiling the Green and Black Paths and Green Cathedrals, explore the intersection of plant and tree spirit work, ecological philosophy, and magical practice. Through alchemy, Kabbalah, the Charubel method, and the Greek Magical Papyri, she uncovers the deep connections between nature's intelligence and human spirituality. Sian's work weaves together folklore, philosophy, and practical magic, offering a bridge between ancient traditions and modern ecological understanding. Passionate about fostering a deeper relationship with the natural world, she continues to teach, write, and inspire through her practice.
