Arcbane

Arcbane is a congenital illness that occurs only in children born with sorcerous blood, or sometimes in those whose blood awakens in adult life. Arcbane is a wasting illness that saps its victims of strength and energy but is only rarely deadly.

Rarity
Children born with arcbane account for about a quarter of all children with sorcerous blood. This number decreases for adult onset sorcery, accounting for about an eighth of such sorcerers. Deaths occuring directly because of arcbane are rare but not unheard of, but it often exacerbates existing illnesses which can lead to death.

Effects
Arcbane drains energy and strength from its victims and often leaves them physically disabled, often confining them to wheelchairs or in extreme cases leaving them bedridden. Sufferers however still can access their innate magic like all other sorcerous blooded people, and reportedly often have a greater connection to their inherent spark than those without. It seems that it is this deeper connection that creates the consumptive nature of the illness.

Cure
There is no known cure for arcbane in either field of medicine. In fact, in the past when victims of the illness were attempted to be treated with arcane and divine magics the illness worsened, and in some cases fully consumed the victim.
