6The present work contains esoteric manuscripts circulated among members of the ONA. HOSTIA contains further details of the sinister tradition of that Order and compliment the information about it already available in the books 'Naos', 'The Black Book of Satan' and 'The Deofel Quartet' as well as that published in the journal 'Fenrir'. The aim of publishing these MSS is to make the rituals and methods of this sinister tradition available to all those who might be interested. Such publication, as will be evident, enables individual potential to be fulfilled, aiding the emergence of a new Aeon. This edition contains the contents of HOSTIA vols. I-III.
