I was hoping to have this more done before posting it, but here we are at the end of November.
My wife and I have talked about running a Neverwhere game as co-GMs for a while now, and it came up again at about the same time as I found out about NAGADEMON, so I decided to make some custom rules for it.
They’re pretty simple.
The rules are here.
The character sheet is here.
That’s it for now, folks! I hope someone finds it useful/fun/inspiring/cool/not awful!
