Brain Ghosts

Everyone should watch Buñuel's The Exterminating Angel.

A Brain Ghost is a strange thing, and not well understood. The appear to be the remnants of psychic trauma, which cohere into patterns and loops. How and why they form are unknown, but hey are not actually spirits and have no true relationship to the traumas that they replay. There is a whole horror genre of (usually awful, but occasionally excellent) novels and plays based around Brain Ghosts, and Baronial children love to scare one another with games that simulate their violent, looping demands.

A Brain Ghost is usually invisible and intangible, but if you can see it it looks like a softly undulating knot of disturbance in the air, about the size of... a human brain...

Brain Ghost

HD0 (1hp), no attacks, mental replay, patterning, unarmoured, incorporeal, speed: immobile and hovering, disposition: mindless. Mental Replay: write a simple script for two to four actors, one scene, mostly action, minimal dialogue. Everyone in the same room as a Brain Ghost must save CHAR each minute or act out the script with anyone else present. Their part is chosen at random. Different people can play the same part. Brain Ghost scripts are often, but not always, violent. If the script is ever played out perfectly, uninterrupted, with any violence in the script actually being inflicted, then the Brain Ghost is dispelled. Patterning: Every time you take part in the script, you take d3 psychic damage. If you play the same roll more than once, you must test CHAR for each time past the first. Each failure gives you, in order:

• The name of the original participant in the drama.
• The personality of the original participant in the drama.
• The memories of the original participant in the drama.

Incorporeal: A Brain Ghost is invisible, and immune to all physical attacks.
