Twillingbottom's Field Guide
Scholars are in disagreement as to the origins or causes of spellscars. Some believe it is a result of a mother being affected by magic while carrying her child. Others believe it is a remnant of The Reaving. Regardless of how it happens, spellscarred individuals are looked upon with fear or derision. The power of the spellscar is said to eventually corrupt the individual. Many suffering a spellscar will be ostracised from their community before this happens.
In some cases, there is no visible marking on the skin, the spellscar will only manifest itself as a pattern or marking when arcane power is used on or by the individual. In other cases, the spellscars appear as jagged cracks in the skin radiating a faint blue light. In rare occasions, the spellscar will manifest as blue fire in different forms; ringing the head of the individual; emanating from the eyes, or appearing as flaming wings.
