Dresden Files

Banefire is the fail-safe that destroys what's hidden under Demonreach island. It is first mentioned in Cold Days.


Banefire appears as a scarlet and blue light becoming a white destructive fire[1] which would kill the creatures imprisoned under Demonreach rather than allowing them to escape.[2]

In the series[]

Cold Days[]

In Cold Days, Demonreach shows the characteristics of Banefire to Harry Dresden, through Bob's projection. According to Bob, a directed burst of energy unraveling the containment spell Merlin would trigger the fire called the "failsafe".[1]
