Born from Katarina Novak's forbidden experiment to merge an ancient Norse grimoire with Kabbalistic water rituals, the Cipher Kraken emerged when she attempted to bypass the protective seals surrounding a submerged archive of Golem creation texts. The entity retained both the insatiable hunger of its mythological namesake and an unnatural affinity for decoding the most complex magical encryptions, becoming the Arcane Seekers' most prized tool for extracting knowledge from sources meant to remain sealed.

The Cipher Kraken exists simultaneously in physical and ethereal forms, manifesting as a mass of translucent tentacles that can extract information from texts without direct contact. It secretes an ink-like substance that reveals hidden text and breaks magical seals when applied to protected documents. Most disturbingly, it can absorb the complete contents of ancient manuscripts, leaving them blank while storing their knowledge within its amorphous form for later extraction by the Arcane Seekers.

The Cipher Kraken serves as the Arcane Seekers' primary means of accessing forbidden knowledge about the Golem's creation that has been deliberately obscured or magically sealed away by generations of Jewish mystics. It systematically undermines the protective measures put in place by the Golem's creators, threatening to expose the most dangerous aspects of the creature's power to those who would exploit it without concern for consequences.
