These are the streets of victorian London.  There are motor cars, men in top hats, women in bustled dresses, but there's a different from the victorian england we all know.  Mixed in with the common folk are some less common folk.  There are gnomes with strange gadgets, halflings hawking googas, elves offering various magical services.  Some of the men and women are waited on by strange animals, anything from draconic looking to fierce dogs that look like they came from hell itself to animal-human hybrids.  There are even mechanical men driven by steam or clockwork that carry large items.  In this london, almost anything is possible.
