Mafia 109. Dreams of the Void Warriors

So, if the "Heroes" player is Mafia, then he's on the same team as the "Master."

Brilliant. At the same time, the "Master" himself quietly registered "Gumer" as completely innocent in the chat. Apparently, he thinks he's in control, playing like he did last time. Or is he actually Mafia with him? That sounds like a plan. One Mafia player controls the town however he wants, while the other just avoids being exposed.
There's another plan: the "Master" is actually Town. Since I'm sure that "Nefele" and "Tox" are Mafia, they're teaming up with "Gumer" and "Heroes."
In short, we need to execute one of the "Gumer-Master" pair. We can significantly reduce the chance of making a mistake by re-voting on the clue from the first day.
