Possessor ★★★★★

I was reading about neural implants used to assist various medical conditions the other day. It was fascinating how people respond to them differently. The implants can add to or modify the recipient's existing identity and sense of self. For some, the implant was a soothing buddy, for others a hulking shadow. I then recalled Possessor and shuddered. This is when the implant becomes a fucked nightmare.
