The Norse, like many of the ancient and medieval religions on polytheism, or worship of numerous gods. Norse mythology originated from the Germanic peoples, but was soon changed post-christianity.
The creation myth for the Norse people revolved around a belief that there was a period of primeval chaos, in which the creation of giants occurred, followed by the creation of gods/goddesses and lastly the spawning of mankind.
Within this belief there are four realms, the yawning void, the home of the giants, the region of the cold and the realm of heat, while the great tree stretched its roots reached through time and space. Underneath the great Tree there is believed to be the fountain of Mimir, a source of hidden knowledge.
Religious rituals and worship were usually conducted in the outdoors. However, they were not just practiced at any place outdoors, but rather under the protection of the guardian trees, near sacred wells, or within the sacred arrangements of stones.
In the Norse mythology are numerous references to such beings as elves, dwarves, and the Norns, which were believed to be akin to that of the fates of Greek mythology (they distributed the fates of mortals). Not only did the Scandinavians believe in overall gods, but rather also such things as personal spirits. Such spirits were the Fylgja and the Hamingja, which were believed to represent the christian equivalent of a soul.
