at least it is clear that Arik is not a guardsman, not a watchman, not an informant, not a Barbarian, not a pirate (if he killed Hermit), not a king... and it is quite possible that he is not a sorceress.
well, you definitely don't have the + status.
It doesn't matter to me, check, make sure. I am always on the city's side, and unlike some hypocritical scoundrels, I wouldn't raise my hand against honest imperial citizens.
killing Medzh would be very appropriate, because no one would suspect him (because of the previous mafia).
Anyway, it's up to you. For now, we need to analyze the clues and compare the data to get a clear list of suspects.
