Veilflame

Veilflame is under utilized, and barely understood. However what is known is it is a pure force of total death, that is harnessed mainly by the C'tan; 'Ruin Mother' and their direct underlings, or creatures of the Nightmare. Not many material uses can use, and nearly none can master it's usage. It is the complete and total corruption of a soul, until it has a 'polarity switch' and reverses its flow into pure negativity. From there, thatt negativity instead of powerful a sentient being when it is 'positive', burns itself out to create large scale and violent empowerments to ones physical abilities.   It can be considered more of a 'martial magic', as it does not create grand scales of spells like fireball, but rather is harnessed through a persons body. Individuals who use Veilflame always have made a deal with some outerplanar being, whether it be creature from the dreamlands, or negative higher entity like a C'tan.   This particular forbidden magic has been spotted on less then ten people, and for good reason. Those who use it have risk of burning their own soul on complete accident, as a soul tainted by wielding veilflame often corrupts into a vile, evil, and sinister human being over time, of which there is no escape and no cure.   Just like Veilflame, it burns forever and is unable to be put out. Should one's skin catch on fire, there is only a matter of time before it burns away completely- as nothing can stop it, until it runs out of things to burn, to which it returns to its domain of the 'Veil', one of the many 'highways' or 'metaphysical lines' that merge through our reality, like Leylines. The Veillines generally only carry energy, of which Veilflame is. Also referred to as Energyfire, or Voidfire.   Veilflame outbreaks are handled speedily to prevent it from spreading over entire nations. Digging deep canals, and removing all materials that could serve purpose to continue to add fuel to the raging inferno.
