This file details how the Masked Duke came to be.
Transcript
I have been experimenting with the possibilities of manipulating and reviving the consciousnesses stored within the Megamycete.
When a person dies, their consciousness is stored and preserved, but over time it becomes diffused and diluted, spread thin throughout the Megamycete and mixed with other consciousnesses and memories.
Extracting and reassembling an individual who has thus diffused has proved a monumental effort.
As an experiment I decided to see what would happen if I used different individuals' consciousnesses to create an entity.
Results:
The results were fascinating. I gathered fragments, re-spooled the threads, and succeeded in creating an individual, birthed anew in this realm.
A success, to be sure, but while his unusual physique resembled a man I once knew, he was possessed of a deeply warped psyche and was missing a portion of his face.
Conclusion:
While manipulating memories to create a person is possible, the creations are flawed and unstable. It will not be possible to manufacture a suitable vessel in this way.
