Great care must be taken that this untamed Spirit i.e. watcher does not rise up against the Priest, and for that reason a preliminary sacrifice must be made in a clean and new bowl with the appropriate sigils inscribed thereupon, being the three grey carven signs of the Rock of my initiation, which are:
They must be engraved upon the bowl with a fine stylus, or painted thereon with dark ink. The sacrifice must be new bread, pine resin, and the grass Olieribos. These must be burned in the new bowl, and the Sword of the Watcher, with his Sigil engraved thereupon, at hand, for he will inhabit such at the time of the Calling of the Watcher and will depart when he is given license to depart.
The Watcher comes from a Race different from that of Men and yet different from that of the Gods, and it is said that he was with KINGU and his hordes at the time of the War between the Worlds, but was dissatisfied and did cleave unto the Armies of Lord MARDUK.
Wherefore it is wise to conjure It in the Names of the Three Great Watchers Who existed before the Confrontation from whose borne the Watcher and His Race ultimately derive, and those Three are ANU, ENLIL, and Master ENKI of the Magic Waters. And for this reason They are sometimes called the Three Watchers, MASS SSARATI and the Watcher MASS SSARATU, or KIA MASS SSARATU.
