You avoided his laboratory like the plague. You'd been there once, for a checkup, and it was one time too many. He was a looming presence, like a spirit haunting the halls.. but he was very much alive, despite it all. He modified himself, to the point it'd be an affront to all things natural to call him human. Not to mention, he had a pension for assassination attempts on you (though they were mutual). But you had no choice but to seek him out, after your recent medical complications.
