This might've been done before, but I can't remember if it has.
So, I kinda started the fallout series not long ago, and I also read an Arcane fic. I was thinking about Zaun's living condition. Yknow, toxic runoffs, pollution, all that stuff. Well, who else can survive in such an invironment? Of course, the protagonist of any fallout game.
It would be really interesting to see the protagonist adapt to that environment. I mean, this guy can pretty much survive anything.
There are probably even more things you can connect them with, but I don't have many ideas. I'll leave that up to the author.

The new Webnovel Library UI sucks. Also imo the old logo was way better.
