The Fall of Cyrog is a popular 14-page PDF adventure supplement for Dungeons & Dragons 5th Edition, designed by Daniel Kahn. It serves as a narrative expansion for the Out of the Abyss campaign, fleshing out a lore-heavy location in the Underdark that was only briefly mentioned in the official Wizards of the Coast module. Lore and Narrative Hook
The adventure centers on Cyrog, an ancient elder brain that ruled over a mind flayer colony in the deep Underdark. Following the "Rage of Demons" event, Cyrog died, but its story did not end there. Orcus, the Demon Prince of Undeath, reanimated the elder brain as an undead monstrosity, effectively turning the entire mind flayer hive into a legion for his undead army.
Players are typically recruited by a patron to infiltrate the lair and destroy the undead brain before Orcus can unleash this new psionic-undead horde upon the world. PDF Contents and Technical Details

Internal instability also played a crucial role in the empire's decline. The succession crises that followed the death of Nebuchadnezzar II in 562 BCE led to a period of political instability. The empire was ruled by a series of short-lived kings, none of whom could match the political and military prowess of their predecessors. This internal weakness made the empire more susceptible to external threats.
The report begins with the arrival of the protagonists at the location of Cyrog. Cyrog was historically known as a bastion of stability in the Underdark, ruled perhaps by Mind Flayers (Illithids) or an ancient Dwarven clan that fell to madness. The players discover that the city has recently gone silent, or a physical "fall" has occurred—literally collapsing into a deeper chasm.
