A work of art for Burning
The Mind Shaft Society originated during an anthropological field trip in search of anomalous phenomena. We discovered these artifacts of an antedeluvian gold rush, and deeper inspection revealed that the depths of the shaft emanate a magical property. Intensive research revealed that it is possible to remove the lingering mental punishment that accompanies exceptionally bad ideas.
If you perform the expiation ritual correctly, you can actually get off your guilt, chagrin, regret, and feelings of "duh!" by cathartically exporting some bad idea, wrong decision, sin, indiscretion, or expression of poor taste you have made in the past year. Or expiate for an entire organization, nation, or culture.
Members of the Mind Shaft Society will be on hand to guide you toward your attempt to undo bad ideas.
