Absolutely adore this and would love to run a devil infested cityscape using this as basis
I think another cool stand alone-ish one that could then be combined with this would be something like "Landmarks of Yerrick".
Something like couple of notable locations in the city and how they differ during the long night to how they usually are, that would probably cover most everything one would need to have their own version of Yerrick in a game.
Ahh thank ya for feedback~
I was originally planning on sequel to have a city map with some neighborhoods and landmarks specified. But was also thinking of shoving in some NPCs and more adversaries. Altho having all that would make it much bigger than Helstalt (about double in pages).
So I'll cut back and take your feedback. Just stick to fleshing out the various locations. Perhaps try throw in a few NPCs as well if I got room.
