Ravnica 5e
Well...it's a bit of a stretch but I'm working on a "City Watch" game that uses the Ravnica guilds as a base.
We'll be running through Waterdeep: Dragon Heist in the Ankh-Mopork style city of Teufelsdrockh.
So...it's not Ravnica basic, and it's going to be more than a little strange. But it does give you a chance to play a cop in a big, oppressive, and hopefully comedic city.
rMail if you want more details--I probably won't be starting proper until mid-December though.
