Fuck if I know
Right now, I'm guessing whatever the streets were like in the Victorian era, with some steam machinery and Arunian-type clothing.
Otherwise, this is just a guess.
On another note, after thinking about the fact that Victorian-style clothing is considered formal in Arun, I thought about it and how the Guardians will probably end up in a situation like that, including Himinn, and then-
And then I searched up Victorian dresses, closed up on one I liked, took out a pencil and drew Himinn in it.
And now there's a drawing of Himinn in Victorian dress on my sketchbook, looking skeptic.
Honestly, I think she looks nice in it, but Himinn's the type to settle for what she considers plain, so unless the person putting her in the dress is really insistent, she probably wouldn't be caught dead in it- okay, wrong wording, she's already dead (I hope you guys remember about the spirit-tier-outdweller thing). She'd more likely take up the traditional Arunian dress.
Also, she's probably not cutting her hair anytime soon, if all my recent drawings of her are any indication. She seems to have grown, too- 15 now, I guess? I dunno.
Should I post it?
