Morgurth

Morgurth is a black liquid refined from the venom  and or blood  of greater  drakes  by  an alchemical ritual which usually includes distillation with strong alcohol in  the presence  of powdered  gold or  platinum; it must then be  protected from sunlight in a glass or ceramic container.Morgurth dissolves  the victim's  brain; at  minimum, it causes a long coma for one to one hundred years.Morgurth is both a nerve poison and a reduction poison, requiring two separate antidotes:  Durad which slows the effects of morgurth and laurre which is a specific antidote.
