A heat swarm is a mass of flying, aggressive, foul-tempered elementals from the Para-Plane of Heat.

A single heat elemental that makes up a heat swarm resembles a thumb-sized ball of fire with vaguely discernible facial features.

When encountered on the Material Plane (which is a very rare occurrence indeed), a heat swarm is most often found in a highly unbearable (by human standards) climate such as an active volcano.
