The colors of flame

Red- bloodfire

A rare and cursed flame which burns only living creatures, curdling their flesh before it eats away the skin. It leaves nothing but bone and fur or hair, and none have yet tested if it can spread along freshly spilled blood. The skincity Viren is perhaps the only place where such fire can be found.

Orange- of hearth and torch

Natural flames said to originate from the plane of fire, wherever that may be. It has long been tamed by mortals as a fine tool for light, cooking, and fending against beasts, though careless use may reveal its own feral nature and show it for the danger it is.

Yellow- flames for gold

Sometimes used by money-changers or alchemists to sift gold from other metals or stone, as this jagged flame burns only precious metals and gems. Most metals it corrodes and ruins, while gems burst or explode. Its use comes in the way it melts gold, as that immortal treasure cannot be rusted or degrade into patina.

Green- demon's breath

Cursed flames known to come about after unnatural magics and dark pacts, remembered by most from a conflagration that burned away the undead armies of the Dead Lords, when they were finally slain. They manifest as they will, consume what they have come for, and disappear without trace or ash. Truly none can say if this fire is a demon itself, merely a tool of dark forces, or perhaps a consequence of twisted wizardry.

Blue- spirits of the dead

Smoke like mist and a pale glow marks these flames as the product of necromancy. Most often seen in the empty sockets of skeletons still fighting, it is also found at the heart of bone lanterns, whispering the memories of a soul long since dead.

Violet- the memory of dreams

When the pulp of a dream birch is lit, the flames burn with a beautiful light. The long tongues of its pyre will plunge any who touch it into a deep sleep. Curiously, when an unwanted memory is written or drawn clearly enough and put in the flame, it will burn away from the creator's mind. It is thought that these are impossible to recover, but an alchemist in Renzez claims to have crafted a restoring poultice using the ashes of burned memories.

White- gentle cleansing flame

A wizard's trick, fire that burns away dirt, dust, and stains and leaving only the shining surface of what lies beneath. The potion that ignites it is quite laborious and time-consuming to brew, so it is perhaps best relegated as a parlour trick for the nobility.
