When there were only 3 options, I liked Espithel's set the most, but holy cow. I just WANT to see Link's setup in action. The idea that the roles are actual EtG players just makes it even more brilliant, for multiple reasons. For one, it lets the players guess a little bit what the other roles can do. For example, I'm pretty sure that there will be roles for Root, Dm, sky, Crockett, JCJ, Kuro, Link himself and myself too. Based on their (our?) past mafia experiences, you can guess what roles might belong to these roles. (if polar opposites get each other's role, that would be hilarious too. Root could become CR and sky could become Link or Dm. Just imagine all the good stuff that can happen)
It only works though if there are no duplicate roles, so I suggest putting that in the guarantee list.
Next up is feedback to Espithel's Domain 1.2. The rules were chaotic at first, because you start off by talking about chants and Threxes and only explain them much later. I think you should start off by stating the primaries: Threxes and Playthings. Then list the single secondary: Purifier. Then explain what stuff like "chants" mean in your setup and then start explaining how they interact with other stuff.
Overall, I think your idea is balanced and it would be fun for a lot of people. A vanilla-based setup is just not my cake though, so I'm an exception. I'm still trying to give unbiased feedback.
CleanOnion's setup: I really like the Lucid Dreaming theme, mostly because I had a blast with playing Scriptwelder's "Deep Sleep" trilogy. I couldn't put your list any higher than 3rd though, because I can't wrap my head around how your setup works. Is it really like, we come up with a dream that's close to the ability we want, and then you give us the power of that ability? Let's say I want an ability that you didn't think about and I describe it to you like a dream: "Tonight I dream that all other dreamers dream nothing.", because I want all other abilities to be disabled tonight. Or what if the civs agree in the thread that they all dream about being doctors and everyone protects everyone? It's not understandable yet what your goal was there, IMO.
I might be biased here, because I'm not a fan of pure vanilla mafia games, but even the most basic mafia games have at least 1 protective and 1 investigative role. A full vanilla setup just doesn't seem to have any value. In a setup like that, it's IMPOSSIBLE to scumread mafia, because all they need to do is to talk like a civilian (or not talk at all). Anyone here has enough acting skills to devolve a full vanilla setup into a guessing game, but some of us are such amazing actors that it would be disastrous for the civvies if 2 players like that became mafia.
If your setup makes it into an actual game though, the one advice I can give is to have VERY strict modkill rules. You can only pull that off if you force all your players to talk, especially the mafia.
