I have a few questions. 

-The Pyrrhic are described as physical manifestations and its also said that the Clairvoyants are the only ones capable of destroying them. This leads me to think that all Clairvoyants carry a common magical means of disposal? Perhaps a universal spell/object to banish them once weakened? It would have to be a means that normal humans wouldnt have access to or else they would help to dispose of them.

-Taking into account that assumption and looking at your character sheet and finding the magic your character is using to be a combative, albeit defensive, type of magic, im guessing we should focus our characters in the same way? Im trying to grasp what kind of magic Clairvoyants can have that would be of use. Obviously any manipulation of elements or energy would work. However if im not mistaken some magic would be kind of useless, such as: Necromancy, Flying/Telekinesis, Illusions/Mind Manipulation, Shapeshifting/Metamorphasis, Teleportation, etc etc. Anything that isnt specifically combative. Could they potentially be useful? Sure. But they wouldnt give you any way to physically dispatch enemies that normal humans couldnt also do. Unless perhaps Clairvoyants are never supposed to fight Pyrrhic alone since only some may have an ability that can physically destroy them?

-Switching gears. Are we apart of an Order of some kind or are Clairvoyants common enough that anyone who possesses the ability is encouraged to find/form a circle and fight the Pyrrhic? We dont quite have a grasp on the world other than it is fantasy-esque and without technology.

Obviously im interested im just trying to clarify some points before I develop a character!
