And Romeo probably visited Arandor.
did he visit? Maybe, although I wouldn't rule out other actions that one might not run from, but rather flee from. But since two people were drinking, and only one block is duplicated, they are obviously eliminated by deduction. Otherwise, I might have thought differently (if I were considering the names of the factions).
I agree about the role of the "Heroist," but I doubt he would go to defend me; rather, he probably wanted to hide, deciding that they wouldn't attack me... (if it was him who visited)
and yes, the clue probably leads to some wise men.
