Druid Circle: Circle of the Flame

This Druid archetype seems almost counterintuitive, as one normally suspects a Druid does not like fire. Druids of the Circle of the Flame are Druids which seek to protect fire as a naturally occurring event, that or because of a fascination with the nature of the Elemental Plane of Fire. The Druid of the Circle of the Flame see fire as a natural force, for destruction and for recreation.
