" A light elf guardian was in Ancient Scandinavia called a fylgja (follower, guardian spirit.). This was a spirit following you wherever you went, removing obstacles in your way, helping you find your way and avoid getting lost, protecting you from injury and death, from eating poisonous food and drinking bad water, from dangerous predators and so forth. It was your guardian angel. Some claimed that the fylgja even walked before you, in front of you, to spot any traps and harm before it could affect you. They were then, when seen by others walking before you, called vardeger (watchmen, guardians.). "
