Only visible to the few who possessed second sight, a Fylga [pronounced: filg-ya] was a guardian spirit that walked with a person. A Fylgja often took the form of an animal that was linked with the owner. For instance, a violent and aggressive person might have a wolf, whereas someone known for their greed might have a pig. The fate of the Fylga was tied to their owner. When the owner dies, so too does the Fylgja.
