Chidili

Chidili served in the Armies of Lolth with Chernobog. She was also a childhood friend of Chernobog. She was sacrificed to a mind flayer with Chernobog. The mind flayer attempted to remove some of her internal organs before starting ceremorphosis. Ceremorphosis failed.
Redacted's hallucinations of Chidili depict her with a large open gash on her abdomen that reveals her insides. All of her internal organs are still there but are hanging out of her wound. Sometimes organs like the kidneys or liver falls out and she needs to pick them back up and shove them in her abdominal cavity.
Due to Redacting knowing much more about Chidili, her hallucination is capable is holding conversations but is still limited to the knowledge that Redacted knows.
