Born from Katarina Novak's experiments combining Peruvian shapeshifting magic with Jewish mystical texts, the Codex Chullachaqui emerged as a unique entity capable of assuming the form of trusted keepers of sacred knowledge. This fusion of South American cryptid essence with arcane European magic created a perfect infiltrator for accessing heavily guarded repositories of Golem lore.

Possesses the ability to perfectly mimic the appearance and mannerisms of any scholar or mystic it has observed, maintaining the disguise until it can access their protected texts. Can absorb the contents of sacred manuscripts through touch, storing the knowledge within its shapeshifting form. Limited by its inability to maintain a single form for more than a day and its compulsion to leave subtle clues to its true nature.

Serves as the Arcane Seekers' primary infiltrator of protected libraries and archives, using its shapeshifting abilities to bypass magical and physical security measures protecting Golem-related knowledge. Creates a network of compromised access points through its impersonations, allowing the faction to systematically extract sacred texts from multiple sources.
