The Arcane Lurker is a spectral entity with the ability to phase through solid objects and remain invisible to the naked eye. It possesses an insatiable hunger for arcane knowledge, which it consumes and stores within its ethereal form. The Lurker is also capable of projecting illusions to mislead and confuse those who might detect its presence.

The Arcane Lurker serves as the Arcane Seekers' primary tool for covert operations, infiltrating sacred sites and extracting crucial knowledge about the Golem's creation. It plays a pivotal role in the faction's quest to uncover and control the Golem's power.
