The Prancing Pony is an inn in a hobbit town - I can't imagine it being too filthy or smelly.
Azog is an Orc. Enough said.
Aragorn needs more baths, but I don't know that I would say 'rank', necessarily.
Orthanc was, at one point, pretty hideous, what with all the Orcs and trees and pollution. I'd call that bit of its history rank.
The Dead Marshes fit the card, for sure.
Turgon. Really? I'm not seeing this one.
Harry Goatleaf was unsavory, perhaps, but not necessarily rank.
Chief Wolf. Wolves aren't that bad, really...I wouldn't choose this one.
Tom Huggins could work. I don't think it's the best choice, though.
Aule was a Valar. I can't imagine him being horribly rank.
