During his convalescence, Hollseher wrote of what he saw in his visions, creating the Liber Malefic — a guidebook, of sorts, of the terrible legendary locations that are rumoured to lie both inside the Chaos Wastes and the Realm of Chaos. Detractors say Hollseher’s accounts are fanciful, rich in allegory and hyperbole; although, his introduction goes far to explain that what is penned in the Liber Malefic is exactly what he witnessed. As the Liber Malefic is too terrible for most to absorb, abridged versions of this book were copied by the Priests of Sigmar, to be used as a primer for the horrors of Chaos that a Witch Hunter might face.
