One of my players is considering making a Reborn character from Van Richten's Guide to Ravenloft. His notion is that the character would be an alchemically-created humanoid cooked up in a lab somewhere by some unknown alchemist for mysterious reasons. With such disparate story elements as witchoil, needlewire, duplicants and those NPC who use them involved, it seems that there should be a good way to tie the character's background to the story. Who might have had the means, knowhow and volition to alchemically create a body and imbue it with life and sentience? What, if anything, went wrong in the process and why is the creation now free-willed and the creator nowhere to be found? Any ideas?
