Just remembered something that disturbed me as a kid from the 1990s EU.
Back in the 90s, Tales from Jabba’s Palace featured the story of the B’omarr monks, guiys so dedicated to a life of ascetic contemplation that they harvest their own brains and put the tissue into mobile spider-droids … as well as the brains of anyone foolish enough (or unlucky enough) to stumble upon them.
As I recall, Bib Fortuna had this happen to him, though he managed to steal another Twi’lek host body later on.
When I first read about it, the idea of being physically removed from your body and all physical sensation, but still remaining conscious, struck me as horrifically awful.
Now that I’m older, I think those spider monks are creepy as hell.
