Seidr was the magic of fate, the weaving of destiny, the bending of what will be.
Practiced most powerfully by the goddess Freyja, and later Odin himself, it was rooted in deep ritual, trance, and herbcraft.
Commonly referenced plants include mugwort, vervain, yarrow, and juniper, though the exact herbs vary in the sagas and folk traditions. These plants were believed to carry magical properties, helping the practitioner see the future, communicate with spirits, or manipulate unseen forces.
