Real Example:
Ruth's archaeological examination of the ancient chamber reveals a small, engraved bone fragment depicting a mythological scene. Nelson recognizes it as a symbol used by a local cult known for ritualistic killings. This discovery becomes a key piece of evidence implicating Dr. Lundquist, as it links her to the occult practices of the cult.
