The next book sounds fun psychotic episodes, booze, and plenty of smoke to be had. The real danger is seems to be from manna it seems it should come with a warning label. Warning: excessive use can cause paranoia, delusions of grandeur, and Schizophrenia. Not that these are bad things mind you.
If Lenamare is scheduled for a nervous breakdown could Tom give him a not so gentle push over the edge using the link? I mean this is the guy that destroyed his life and enslaved him? It might be a fun way to pass the time since Tom does not need to sleep, learning about magic might be easier especially if you have a burning question in the middle of the night.
By the way your paranoia and anxiety is completely justified I heard mention of a fiendish plot most foul. It involved relieving you of your reputable smoke..:-“
