Morley is one of the Islands in the world that Dishonoured is set it. It's locales are based on real world irish and Scottish cities and places,
so i'm assumming like dunwall is based on England, Morley would be very Celtic , If they ever go there
they could make such a great Locale, A morley High King etc, Celtic Steampunk awesome!, warring kingdoms, More extra dimensional beings etc. Celtic Steampunk it has to be done! .

A lot of places can be done inspired by real world quality/odd architecture. If they are gonna expand the world via gameplay they will create something amazing.

Well obviously, but my point is Celtic steampunk would be brilliant.

Well it isn't steampunk for one thing because there is no steam or brass involved. This is industrial and it will work with a lot of European architecture, because it is really stylistic and odd looking.
