The Province of Amalur
Where these mysterious bonfires come from nobody knows. But there impact on the Shadowfell is immense. They have also been nicknames ‘Soulfires’
These Bonfires provide hallowed ground and protection for the mortals living within the Shadowfell. For this reason many cities, villages, and towns spring up around the bonfires.
The more evil souls that are sacrificed to the Bonfires the brighter they grow and the more purified the surrounding area becomes. Some of the largest bonfires have even returned color to the surrounding areas.
The creatures within the Shadowfell revile these flames as they protect their prey from the hungering jaws of evil. Their only recourse is to corrupt or tempt the souls of mortals into desecrating the flames, dimming their light and their protection over the surrounding area.
