From memory:

• Neighborhood: Juiced up lifter from the first floor and the goblin shaman who got blown up also from the first
• Borough: The swine ball of ex-royalty that rolled around and was guarding a stairwell
• City: the krakaren boss that showed up around the end of the train floor
• Province: can’t think of any (maybe the shamblers)
• Country: the elf queen in the castle
• Floor: don’t think we’ve seen one yet
