Flagrans

Flagrans, like the element that they're connected to, are volatile and temporal. The vast majority of them are harmless, letting in enough heat to warm a winter's night or to provide a warm gust on a summer day. These look like orange sparks, roughly spheroid, and last at maximum seven seconds.
There are more permanent Flagrans, though. They can be found in the calderas of volcanoes, at the origin of hotsprings, and the biggest imaginable is even theorized to be at the center of the sun. These permanent Flagrans are marked hazards by cartographers with the

symbol.

Manifestation

Flagrans typically appear as spheres of fire, sizzling and crackling like a campfire. Larger ones "roar" in a continuous bellow.
