Infernalcane

An Infernalcane is a massive inferno-cyclone of shifting, multicolored flames. Anything caught within it is dragged inward and incinerated—one of the purest expressions of fire’s destructive power in the natural world. If you see one coming, you’d better be behind fire-resistant (or, ideally, fireproof) shielding. Otherwise, you’re about to learn what it feels like to be barbecue.
As this walking firestorm advances, it scorches the ground beneath it, stripping heat and fire-mana from the land. In its wake, the region can be left desolated and unnaturally cold, as if the warmth has been burned out of the world itself.

Manifestation

The Infernalcane forms when fire mana saturates the atmosphere to extreme levels, birthing a towering inferno cyclone. Once it begins, the vortex continuously pulls in more and more fire-aspected magic of nearly any variety feeding its growth and volatility.
It will also draw in traces of light mana, visible as multicolored flames swirling through the core of the storm. The phenomenon often starts low to the ground, building into a spiraling column as it “hunts” for the lowest pressure and hottest concentrations, inhaling heat, embers, loose flame, and ambient mana as it goes.
One of the strangest effects is the temperature inversion around it:
Near the vortex: the heat is overwhelming searing, oppressive, and immediate.
Just outside that zone: the air can feel sharply colder than normal, as though warmth is being leeched away.
People close to a forming Infernalcane often report a sudden, violent drop in temperature followed by a surge of intense heat as the cyclone fully ignites and stabilizes. Localization
Infernalcanes are most likely to occur in regions where fire mana naturally concentrates, including:

Localization

Infernalcanes are most likely to occur anywhere fire mana naturally concentrates, including:

• Volcanic regions
• Deserts and badlands
• Areas along medium or major fire ley-lines

(Minor ley-lines can produce a small Infernalcane, but it is rare.)
They may also form during extreme heat events, especially when many fire casters are active in the same area over a short period—effectively overcharging the atmosphere with fire mana.
Infernalcanes are a frequent and ongoing hazard across the continent of Natsu’s Islands, where ley activity and volcanic terrain make the conditions for formation far more common than in most regions.
