Keep in mind that the novella has been reprinted and edited over the years, so you may encounter slight variations in the text.

If you can provide — such as the author’s name, a brief quote, the subject matter (e.g., history, fantasy, cybersecurity), or where you encountered the title — I will gladly write a specific, well-structured report for you.

In the official Out of the Abyss book, Cyrog's death is mentioned briefly. This supplement expands that lore: Cyrog is not truly dead, but has been turned into an serving Orcus. If the adventurers fail to stop him, Orcus will use Cyrog and his mind flayers to unleash an undead army upon the world.
