Created during one of Katarina Novak's reckless experiments, the Grimoire Grootslang emerged when she attempted to bind an ancient Jewish mystical text with artifacts from African shamanic traditions to unlock new insights about clay animation. The ritual went awry, fusing the grimoire with the essence of the legendary elephant-snake hybrid, resulting in a sentient repository of forbidden knowledge that hungers for more arcane secrets.

The Grimoire Grootslang exists in a constant state of flux between book and beast, able to transform from a leather-bound tome inscribed with shifting Hebrew and African sigils to a massive serpentine creature with elephant-like features. It possesses the ability to absorb written knowledge through physical contact with texts, instantly deciphering any language or code related to animation magic and golem creation. When threatened, it can exhale clouds of animated clay dust that temporarily blinds opponents while revealing hidden magical inscriptions.

Within the Arcane Seekers' hierarchy, the Grimoire Grootslang serves as both an intelligence gatherer and knowledge interpreter, infiltrating sacred libraries and ruins to consume ancient texts while providing Katarina with insights that would take scholars decades to uncover. It represents the faction's willingness to combine disparate magical traditions without regard for cultural boundaries or taboos.
