Breath Weapon (Su)

A pyrogeist can spit a cone of spectral fire that damages living creatures. When a creature fails a saving throw against the pyrogeistâs breath weapon, the creatureâs flesh ignites in ghostly flames for 2d6 rounds or until the pyrogeist is destroyed. While the creature is affected by the flames, it is illuminated as though under the effects of faerie fire and takes 1d6 points of negative energy damage at the start of each turn. Subsequent breath weapon attacks donât increase this damage but can extend the duration. An affected creature can attempt a DC 22 Fortitude save as a full-round action to quench the flames. The save DC is Charisma-based.

Pyrokinetic Whirlwind (Su)

A pyrogeist can transform into a spectral whirlwind (as per the universal monster rule) to entrap its victims. Creatures caught in the whirlwind take 10d6 points of negative energy damage each round. A pyrokinetic whirlwind does not create a swirling cloud of debris when it touches the ground.

Rejuvenation (Su)

A pyrogeist that is destroyed restores itself after 2d4 days, forming near its mortal remains. To permanently destroy a pyrogeist, its corpse must receive proper burial rites, including a sprinkling of holy water.

Soul Consumption (Su)

The spirit of a creature that dies while subject to a pyrogeistâs pyrokinetic whirlwind is trapped within the pyrogeist (as per soul bind) until the pyrogeist is destroyed or chooses to set it free. The spirit remains trapped whether or not the pyrogeist is in whirlwind form.

Pyrogeists are the burning ghosts of arsonists and pyromaniacs who were killed in the fires they started.

Whether the pyrogeistsâ deaths were accidents or suicides, the horribly painful and often humiliating deaths create pyrogeists from the arsonistâs or pyromaniacâs soul. A pyrogeist is a mass of spectral fire that emits no heat and damages only living creatures. A large face floats upon its surface, resembling a twisted mockery of the person the pyrogeist was when alive. A pyrogeist haunts the area surrounding its remains and is consumed with a desire to immolate others. A pyrogeist most often haunts its victims with terrifying illusions before engulfing them and adding their souls to the creaturesâ perpetual torment.

The form of a pyrogeist flows and roils, its large face appearing and disappearing along with the faces of the other souls the pyrogeist has consumed. The ghostly inferno changes colors based on the pyrogeistâs mood.

Most often an angry red and orange, as of flickering flame, the pyrogeistâs hues might shift to an envious green, a calm blue, or a haughty violet at a momentâs notice.

Although a pyrogeist rarely chooses to communicate with the living except when mocking or haunting them, when it chooses to speak, its voice sounds like roaring and crackling flames.

Pyrogeists are obsessed with sharing their torment with the living, but they are too clever and sadistic to simply immolate their foes. Pyrogeists prefer to first drive their victims into paranoia and insanity. When feasible, they first start with minor events that could be explained as accidents or unfortunate events, such as by using mage hand to push flammable items near open flames or ghost sound to emulate the crackling of a fire in another room. When the pyrogeistâs victim starts to doubt its senses, the pyrogeist inflicts increasingly horrid nightmares that always involve fire. These nightmares usually culminate in people or places the victim loves being set ablaze, often by the victimâs own hand. The pyrogeist then uses its major image spell-like ability to bring these nightmares into the waking world, causing its victim to see charred corpses or dancing flames wherever it looks. Eventually, the pyrogeist moves in for the kill, destroying its victim with whirling spectral fire that annihilates flesh and bone but leaves clothing and other items intact.

A pyrogeist can make its victimâs torment endless by consuming the victimâs soul, creating another face that flows across the pyrogeistâs churning form. Pyrogeists are reluctant to release souls it has entrapped, usually doing so only as part of a bargain that ensures its ongoing existence or promises additional souls in exchange.

Pyrogeists draw pleasure from burning victims with their ghostly fire, but they are aware that this manner of death leaves distinctive clues for ghost hunters. As the pyrogeistâs attacks deal negative energy damage, they cannot harm objects, clothing, or equipment. To cover its tracks, the most devious pyrogeistsâespecially those that have been destroyed and rejuvenated in the pastâignite normal fires to hide their tracks. Although a pyrogeist might knock over an oil lamp or shove a flaming fireplace log with its mage hand spell-like ability, it prefers to have its victims set the blaze on its behalf, perhaps promising an end to their psychic torment in exchange for an act of arson.

Identifying a pyrogeistâs supernatural burn marks is much more difficult after a mundane fire has swept through a location.

Pyrogeists choose their victims based on their proclivities in life and the circumstances of their death.

Some pyrogeists prefer to target victims of certain classes or occupations, or by targeting buildings of specific architectural styles or colors. Pyrogeists that formed from murderous psychopaths often continue gruesome trends in undeath, such as collecting trophies from their victims or leaving certain calling cards at crime scenes.

Other pyrogeists spend their time forcing victims to recreate the circumstances of their own deaths.

Putting a pyrogeist to rest permanently requires burial rites be performed with at least some piece of the pyrogeistâs mortal remains. As those remains have usually been reduced to little more than ash and bone fragments, they often go unnoticed among the smoldering wreckage of a destroyed building. A pyrogeist senses when its mortal remains are disturbed and usually moves quickly to prevent anyone from disturbing them.

Habitat & Society

Pyrogeists most often form in heavily populated cities, where structure fires are more common and the anonymity of crowded streets allow arsonists and pyromaniacs to blend in as they do their wicked work. These pyrogeists have no contact with their former families or friends, but they sometimes seek out their old acquaintances to become their first victims. Pyrogeists can also originate in remote villages or in the wilderness, usually during forest fires or other calamities triggered with malicious intent.

Pyrogeists are almost always solitary creatures, so consumed by their hunt for souls that they rarely interact with anything else, living or dead. On rare occasions, multiple arsonists die together and merge into a single pyrogeist, sharing a morbid coexistence. These pyrogeists are usually the most erratic, as different personalities vie for control.

Powerful necromancers sometimes attempt to create or control a pyrogeist, in search of an incorporeal assassin that prevents its targets from being brought back to life. Pyrogeists resent these attempts, making them highly dangerous minions; if the necromancerâs control slips enough to allow the pyrogeist any amount of freedom, the incorporeal horror would surely focus its murderous attention on the one that enslaved them.
