Sing a Song of Blackbirds
Ash wraiths are the undead manifestations of angry flame spirits born from the souls of spellcasters that died in a mundane or magical fire. They appear as vaguely humanoid plumes of ash and soot with eyes like hot embers. They speak common, but are not very reasonable or intelligent. Mostly they are filled with simple, inexplicable rage. Their touch burns as though it were a raging fire, and sparks constantly swirl about them.
