Gothtropolis.

At least that's what I named it! One of the many different worlds you can visit within the Oasis - and featured briefly in the introductory fly-thru when we fisrt enter the Oasis. It is meant to be evocative of many movies and settings with a certain gothic, art deco look: including Brazil, Dark City the Batman movies and Metropolis. Also - check out Gaelle Seguillon's take on the same concept (here on ArtStation).
