This here is the concept art I designed to show you all Topaz's home-world. "Nameless" Junction(We don't have a real name for yet), is a Steampunk styled world that is filled with pollution. That vegetation you see there? Its fake. Her world is too polluted to host plant life. The rivers are polluted as well, fish are mutated or dead and there are water treatment plants everywhere.
For now this is the only concept art I have, I will be uploading more as time goes on. So please bear with the sketch rushed feel of this. I'll get better I promise! I'd love to hear your opinions on what I can improve!
