Nyths are creatures very similar to will-o'-wisps and the two species can communicate and have been known to ally with each other. Nyths are often mistaken for wisps but some northern barbarians can supposedly tell the two apart, naming nyths "wildfire" and thinking them to be evil spirits. Nyths have a slightly wider range of colouration than wisps. Nyths are sometimes recruited as guardians and take great pride in defending their homes against specified intruders.
