Final answer:
In Norse mythology, the most feared entities, which were believed to wield control over individuals' destinies, were The Norns. Unlike Freyja, Odin, or Thor, who were connected to diverse elements and spheres of life, The Norns were uniquely tied to the determination of fate.
Step-by-step explanation:
The Norse god feared the most and believed to control people's fates were The Norns. These were a group of deities known to dictate the destinies of both gods and men. Much like the Mesopotamian and Ancient Egyptian societies, the Ancient Norse religion was also polytheistic with various gods and goddesses attributed to different elements of nature and life. For instance, Freyja was linked to love, beauty, and fertility, Odin was the chief god associated with wisdom, war, and magic, and Thor was the god of thunder. However, none of these gods and goddesses held sway over fate and destiny, a role reserved for The Norns.
