If an unfortunate traveller were to stray onto the twisted roads that lead from the northern forests into the Chaos Wastes, he might be paid a visit by a most unsavoury individual during the dark of the night. A shuffling, muttering figure stalks these lands, his moth-eaten robes gently clinking with vials containing unimaginable concoctions, which he is seeking to test out upon those he can catch or deceive. A devotee of the plague god Nurgle, this mysterious apothecary is quite, quite mad, though he once bore the respect of physicians, alchemists and scientists across the length and breadth of the Old World.[1a]
